Why do we (mostly in the western hemisphere) not eat insects? | 1. People think insects are gross, and we don't want to eat things that we think are gross. 2. A lot of people don't like seeing the fact that their food is an animal. Eating things with the head still on it, or eating things that are recognizably body parts, tends to turn people off. Because bugs are so small, it's hard to make food out of them without just eating the whole thing and recognizing that you're sticking a bug in your mouth.Taco Bell Grasshoppers Taco Bell Grasshoppers Taco Bell Grasshoppers Taco Bell. |
Why some people hear instruments while other people hear lyrics primarily when they listen to music. | I play mainly percussive fingerstyle acoustic guitar and I'm self taught. When I started figuring out how to play, I'd separate the baseline, the melody, and the percussion. Because I'm so focused on the melody and the notes that make it, I never pay attention to the words that are actually sung to the tune of the melody if that makes sense. I couldn't tell you why everyone is different, but judging by everyone else's post, it sounds like musicians focus on the instruments they play and singers and vocalists focus on the lyrics. I'd say to the not-musically-inclined, they'd probably listen to lyrics as it's proven that a catchy hook coupled with a tune is what grabs people's attention. |
I sent a physical letter to Barack Obama and received an email in response. I never disclosed my email address. How did this happen? | When I interned for the state assembly we keep a record of everyone's email/number/address on a program called LCMS. Every time a letter would come in we would look up the person or address to see if they were already in the system and then mark that they mailed us something, what they said, and then reply through email. It's quite normal.Only government officials and workers can access LCMS and most of the data is pooled from voting registrations and constantly updated. Everytime we campaign cold-call, people would angrily demand how we have their phone number. Voting registrations people! You're in there forever! |
Why do people faint at high G forces? | The G-force forces the blood in the body to drain away from the brain, which causes you to pass out. It doesn't cause permanent damage. Part of it is just the terror of what's happening to them. |
Why can individuals create mods for games that improve the graphics drastically, but developers can't include them in the original game? | Those mods add a lot of data to the game that only those with high-end computers can typically handle utilizing. Leaving out the very high-end options could allow a game to be 8 gigabytes rather than 12, for example, and would be preferable for 90% of consumers anyways. A lower file size is beneficial for a huge number of other different reasons as well, such as load times. It also frees up time for the developers to work on/optimize the other graphical settings and other portions of the game.1. deadlines2. devs try to make the game run on most systems this requires sacrifice3. The game could have come out years ago or use assets made many years ago that where re-used from the last game.4. modders can focus all their attention on just one to a few things |
why casinos always win? | They carefully set the odds so that the players win just enough to stay interested and think that just maybe they can win a mint, while leaving the advantage on the house's side. For example, if they were offering a bet on a coin flip, with heads and tails each being an exact 50% probability, they'd pay 48%. It doesn't matter which way you bet - while there are bets with better odds than others, every bet in the place has a house edge. |
Why does bottled water cost more than soda or beer? | The cost of anything is not related to it's intrinsic value - ie the value of the raw goods it is made out of + the manufacturing costs. IT is simply a function of what consumers will pay for it. A company will work out a function of how many sales they can get for a product at a given price, and then choose the price that returns the maximum profit. |
Why the shower curtain gets sucked in to the shower when the hot water is turned on? | From _URL_7_, [this is the explanation] that comes closest to being simple and straightforward that I've found. |
How does stock market work to improve the economy? | Lets say that you own a lemonade stand. It does pretty well, people like your lemonade. But you know you could make a lot more money if you had a lemonade store downtown. That takes a lot of money to open. You ask your mom, and she only has $50 to lend you. You ask around town, and again all your friends can only spare about $100 each, which is not nearly enough to open a store. One option is to go to a bank. They want a really high interest rate though, and have other terms that you don't want to agree to. One bad month of missed payments, and they will take your store! Another option is to form a company, and sell off ownership in it. To do this you issue stock shares. So your mom can buy $50 worth of shares, your friends $100, or $20, or whatever they can afford. You can raise the money to open your store. You hire workers at the store, and make some money- and now you have made a contribution to the economy. Your friends may say they no longer want to own a piece of your store anymore, so they can now sell their shares to someone else. The stock exchanges you read and hear about work this way. Many small investors can invest in businesses and own a piece of them, hoping their value will increase and they will be paid out dividends. This is pretty much the only way to raise an extremely large amount of capital. Even if a company like GM could find someone to loan them $300 million dollars to build a new factory, that person would rather not have so much money tied up in a single company. |
. Why is Shaun of the Dead so highly regarded among horror film fans? | It was a very genre savvy yet subtle parody that also played well as a movie on its own merits. *Scary Movie*, in contrast, was a more heavy handed, over the top parody that didn't really let it be a real movie. |
Mechanical Keyboards and how they differ. | Mechanical keyboards often use [Cherry MX switches], as opposed to the more common rubber dome/membrane mechanisms. There are other types of mechanical switch , but IMO Cherry is the most common. For me, the biggest difference between the two types lies in the 'activation point', or how far down you have to press a key to get it to register. With rubber dome/membrane switches, you have to push the key all the way down to get it to register. This isn't a problem for the vast majority of computer users, but heavy users like typists and gamers make use of lots of quick, repetitive motions to get anything done, and stiff domes are more likely to cause RSI over a long period of time. With mechanical switches, on the other hand, the activation point is around halfway down the key, meaning you only have to push a key around half of a full keypress in order to get it to register, solving the first problem. Second, with Cherry MX switches, the 'stiffness' of the keys can be controlled simply by picking a keyboard that uses a specific type of Cherry switch, like Cherry MX Red if you want something 'light' and easy to type on, or Brown if you want something as light as red, but with tactile feedback so you know you activated your key. |
Why does saliva feel like it has no taste? Is it actually tasteless? | In order to taste something you need a receptor for it. Different receptors taste different molecules and the combination gives things complex identifiable flavor. We purposefully don't detect our own mouth secretions, we lack the receptors, as they would create too much noise with other tastes. |
How did the color green become associated with being correct, while the color red became associated with being wrong? | [Citation needed] for all the answers so far. It's a really interesting question, and even though this is ELI5 it deserves a well-researched answer supported by evidence.This is mostly western culture. In Japan for instance green is associated with the jungle and thus bad due to the many dangers of the jungleYou should ask /r/askhistorians. So far, people here are just saying what they *feel* like the answer is1. As a practical issue, artificial light available until very recently was mostly red and green. Incandescent light sources like glowing metal or open flame don't make much blue, so you're looking at red, green, and the combination therof - yellow.2. Our "go-caution-stop" system derives from British railroads. Initially, red was the color for stop - red being an ancient symbol of caution and danger, green was used for caution, and *white* was used for go. However, after a lamp broke and caused a dreadful accident, they rearranged it to the current systemVery successful influence campaign by the wealthy family who owns the color green. Not so much by their rival family. |
Why would you download "Find my iPhone" on your own phone if you can't use it without having your phone? | You can actually find it from the website, find my iPhone, and it works. I don't know if you need the app, but it definitely finds your iphone.If you lose one device you can use any other device to find it. Lose your phone, find it with your iPad, Mac, or iPod touch. Lose your iPad, find it with your iPhone, Mac, iPod touch, etcUsually the point is that it sends the data to somewhere else so you can check where it is without having it. |
Why don't states in the U.S have high speed rails connecting their major cities? | I think part of the problem is a lot of the commuter train lines are subsidized as it is. I know Amtrak is subsidized cause it can't make it on its own just off of ticket sales. So states are hesitant to build a train line if the ones that already exist are subsidized.This US is very large and spread out. It would be prohibitively expensive to build cross country high speed rail. There are some smaller denser pockets which will probably get light rail soon, like Los Angeles to San Francisco and San Antonio to Austin.Car and gas companies. In the 50's the car companies created a firm that would go to cities with public transportation and convince the cities to dismantle them since cars are a more economic and viable option. |
why do many stereo receivers display their volume "backwards" (where zero is the loudest)? | Also, loudest is not always 0. Since have a 'reference' level that is 0 and you can actually go above that. _URL_0_ |
How does jumping off bridge into water work for suicide? | Surface tension of the water causes it to basically be as solid as concrete for the first instant you'd hit it. Contrary to popular media, you can't survive a fall from a massive height by splashing into water. If the impact with the waters surface doesn't kill you, shock, drowning, or injuries will. |
If Bill Cosby has been drugging/harassing women for years, why would they only now accuse him? | They wouldn't. He's been accused in the past, but his lawyers successfully silenced the accusations through huge legal threats. It's only when several people realised they weren't the only victims and that he wouldn't be able to silence them all that they've come forward. [Heck, one such instance was even public but we just didn't pay attention because he managed to make it seem like nothing].There is usually a backlash against anyone claiming sexual assault, especially against a popular and influential person. With time, it can actually be easier, especially as more people speak out. |
Why can we recreate sounds and images on our minds very well but not smells or tastes? | Burning brakes .. singed hair .. burnt popcorn baked bread .. fresh cut grass Still don't smell anything? |
How can athletes cost so much, earn so much and still make a profit for their teams? | Because you have millions of fans spending billions of dollars and the money goes to a few dozen players. A baseball team has 25 players on the roster. Teams' overall payrolls are something around $100 million. The team sells 2 million tickets at $40 -- that's $80 million. Those 2 million fans spend $20 each on food, beer, etc. That's another $40 million. Then there are the local TV rights, radio rights, and local sponsorship/stadium advertising deals. And the team's cut of national TV/streaming deals, merchandise licensing, sponsorship deals, etc. Those can total a few hundred million dollars. Sure, the team has some stadium cost, non-player employees to pay, equipment, etc. but the players is the biggest line item. |
Why do many people consider it racist to compare the gay rights movement with the civil rights movement? | The sentiment I've heard is that the government responded to 1960's civil rights events much more violently than they do gay rights events. Black protesters were commonly sprayed with fire hoses, attacked by police dogs, and beaten by riot police. Gay rights events have faced much less official opposition. Personally, I haven't heard of such a thing happening at a gay rights protest. I'm guessing the feeling is, for a gay rights protester to compare himself to a civil rights protester is diminishing what civil rights protesters were subjected to. |
Why we experience the sensation of falling in our dreams/when we wake up | Saw a video recently that suggests this falling feeling is an ancient reflex we developed as tree dwelling primates who'd need to be able to grab a hold of something before falling out of a tree. Not so sure about it as I'm not sure what would trigger this response while lying in bed. |
ELI: Evolution, and how we are so certain of it? | Evolution itself is a very simple process, based on 3 facts: 1. Animals are like their parents: Your body is built from instructions in your DNA, and you get your DNA from your parents. This is why people look like their parents.2. Animals are not *exact* copies of their parents: There are some random changes made in the DNA copying process, called *mutations*. You are like a copy of your parents with a few very tiny random changes made.3. How many descendants an animal has is affected by your DNA: If an animal is in some way a little better suited to their environment, if they're a little stronger, a little faster, a little smarter etc., they are a little more likely to have surviving offspring. The rest flows naturally from that. Traits are passed down through the generations. Slight changes happen randomly. The changes which happen to end up making a creature more suited to its environment get passed on to more of the next generation, and become more common. Over a long time, those slight changes add up to big changes. That's the simplest explanation of evolution I have. Other posters have covered how we know pretty well. |
How does Giant Eagle not lose money by offering Fuel Perks? | What they're losing on gas they're more than making up on food. Also, chances are that 1,000,000 people are spending $100/week on groceries. That would mean the grocery store is making $100,000,000/week anyways which is great. |
What happens when you crack your knuckles? Is it bad for you? | I think it's bubbles of synovial fluid popping in the joints. I haven't read any evidence that its harmful. |
Why are most canned foods high in sodium? Doesn't the canning process eliminate the need for preservatives? | Humans also have what is known as a 'bliss point' in which foods are perfectly balanced and we love them. It's true for sugar and salt. So food companies want to give you that 'bliss point' and they have been engineering food for years to have fat, sugar and salt levels that make you achieve said 'bliss point' and crave these foods time and time again. Finland realized that they were eating too much salt in the 70s and started an informational campaign on lowering salt contents in their foods and making better labels to indicate if the food had high levels of sodium or was healthier. The government informational campaign, along with their food industries, were able to lower their population 'bliss point' for salt and their sodium intake diseases has gone down. _URL_3_ also, people traveling to the US often say that their find american food extremely salty |
Why do car companies release their next year cars mid way through the current year? | *Not for 5 year old:* Cars are released when they're released. Depending on the scope of the vehicle they have anywhere from a 24 month to 60 month development and launch time. They're all on strict schedules, and generally meet the schedule. Let's say a manufacturer has 20 cars in its lineup. Sure, since there's a strict schedule, you could start development of the entire mix so that all 20 are released exactly on January 1st every year , but how do you allocate your resources to do that? Instead of having seven plants, you need 20. Instead of 5 engineering teams, you need 20. And the same goes for suppliers ; they're unable to support 20 new cars at the same time, either, because they have to manage their own resources. When you hear about how the auto industry is important for an economy, it's not because a plant employs 2000 people; that's only 2000 people. Cars are complex pieces of machinery, and they take many more thousands of people to design, plan for production, supply parts for, and coordinate. Then there's marketing, sales, finance, customer service, government affairs, and so on and so on. And this is at every level. The manufacturer has to do operate this way. The tire supplier has to operate this way. They robot supplier has to operate this way. The electrical components supplier to the robot supplier has to work this way. The copper supplier to the electrical components supplier to the robot supplier has to work this way. Building a mass production car is an incredible feat. It's quite literally a modern marvel . |
Why does MLP attract so many weird adult fans while other children's cartoons do not? | Its story had continuity and the fantastic world is fairly well developed the humour is for all ages the lessons are good basically its just a really good show. Avatar, Dragon Ball, Pokemon off the top of my head are childrens shows that appeal to an adult audience what makes MLP different is that its so absurd and criticized that the fans become much more isolated and it isnt as easy to casually be a fan. Basically the fans become more devoted in response to the increased criticism of a reasonable interest in a nice show. But what about the porn stuff!? i dunno people make porn stuff i guess and thats not really op's question |
Why is it that certain commodities are untenable to produce in relatively small amounts but sustainable to the business when mass-produced? | Generally it's about economy of scale. The amount of work that goes in to producing something is spread among all the items that sell. So if it costs $100 to do all the work to design and produce a lightbulb and you make one, you have to sell it for more than $100 to make any profit. And that may be a price nobody wants to pay. If it costs $5 more to make 100 of them, because the base coat is mostly design and getting all the tools you need so you only need a few more dollars to make a bunch, you can suddenly sell them for $2.50 a piece and make more money.Cost of production decreases with the amount produced to a point. Usually when the cost of labour and tools/machines outweighs the cost of materials. For example, if I have a machine that costs $100/h to run and an employee I pay $10/h to operate it and materials that cost $1/unit, the more I can produce in an hour, the less my production costs turn out to be per unit. If I produce 1 unit an hour it would cost me $111/unit , if I produced 100 units it costs me $1.11/unit. I think something along these lines anywaysImagine selling one grain of rice. The cost of packaging it, putting it on the shelves, and having a cashier ring it up is going to exceed any profit you would make. They would have to charge maybe 10 cents a grain to make it worthwhile, and no one is going to pay that. A ten pound bag of rice, on the other hand, is only going to cost a little more to handle, but they can charge a price people will pay and still make a profit. |
Why when you are lacking sleep do you get black marks under your eyes, then when you catch up they disappear? | Sleep deprivation causes a cascade of hormonal ill effects, including reduced leptin, human growth hormone, and thyroid simulating hormone; insulin resistance; and increased cortisol. Cortisol increases blood pressure and dilates blood vessels, including the capillaries under your eyes, causing he dark blood circles under your eyes. Hence, it's important to get your beauty sleep. |
How does killing the heads of terrorists groups actually help end terrorism? | in organizations where the #1 actually are the head of the chain of command, the bottom tiers won't be able to coordinate as effectively. however in organizations where left hand does't know and doesn't care what the right hand is doing, killing #1 on the left hand don't have any effect on what the right hand is doing. |
how come when other animals mate with their siblings, no birth defects are typically present, but when humans do, there is a high chance of birth defects? | Yeah if you've got defects in the animal kingdom then you're on your own and not for very long |
What would the Earth look like if you're in a helicopter and an earthquake happened? | I am speculating here from having personally seen rock quarry blastings, but as the explosion spreads outwards you see a shimmer that is a pressure wave. It's literally a pressure gradient of air. It wouldn't seem too far of a jump that the earth moving such a large mass upward/downward/sideways even a short distance would cause a very similar effect in the air. I would think that the shimmer may not be as defined as an explosion, but definitely there should appear to be a distortion on the light and air in the area where there is movement. |
Why do the Fruit of the Loom socks that I always buy come in a resealable bag? | If i were to guess, it has to do with the sealing process. to seal a plastic bag, you need heat. It could be that there's a risk of fire or damaging the products to heat seal cotton socks in a plastic bag, so they use reseallable bags to circumvent this process.Maybe to encourage you to reduce, recycle, RE-USE? One less baggie in the landfill if you use it to store/organize things like a regular ziploc. |
what the hell this John Cena thing is? Why is he everywhere? | John Cena is a WWE wrestler. In WWE, it's common for wrestlers to have flamboyant, LOUD introductions for their arena entrance. This one just happened to become a meme, similar to 'IT'S ME AUSTIN, IT WAS ME ALL ALONG, AUSTIN' and the like. |
Why is high fructose corn syrup considered so unhealthy for you? | A simple explanation would be that normal sugar increasing in intake would result in an increase of insulin - leading to no longer feeling hungry. Fructose doesn't cause the same reaction in insulin in the body, and is converted more readily in to fat . So not only do you not get the reduced hunger as you consume more, it is more easily store as fat in the body. Bad times. Edit: spelling |
Why do we follow the Gregorian calendar globally and what would be feasible alternatives? | Answer: Because of capitalism and the incredible power that western economies have, globally. Alternatives: Not as long as western money is running things, they won't be viable. But basically any calendar system can work as long as it respects the math of the earth's orbit. We only use this one because of the global economic power of the west. |
How did the UK NHS system work, what did the recent reform bill do to the system and what are the reasons for it? | > why is competition good in healthcare sector? Essentialy it's not, but we have lots of people who give lots of money to the people who run our country and then by chance the people who run our country decided that they have the same beliefs as the people who gave them the money. > And if it is really as bad as everyone says it is, why did the government implement it? Because when they stop running the country they can now go and get very nice comfortable jobs which pay them millions of pounds per year in the companies which all their friends who run the healthcare companies own. Also, it's worth noting that the changes aren't UK wide. I live in Scotland, and the people running things here decided that reform sounded like a bad idea, and so haven't undergone the reforms that have taken place in England. This means that the nature of the NHS in England and Scotland has diverged to a very large degree. |
If a dead body is buried with baby fruit tree planted over it, when the tree bears fruit, would that fruit contain any identifiable human genetics/traces? | I read an article some time back about a specific combination of isotopes found in plant life along rivers that had annual salmon breeding. I'll try to look it up so you can verify yourself. This is no where near what would be considered genetic traces, however at the atomic level it appears your atoms will become the trees atoms. Edit: Relaxant article: _URL_2_ For eli5 just read the introduction. |
What's so wrong with steaks cooked well done? | Steak connoisseurs tends to react badly to taking a good steak and preparing it well-done because the process of overcooking it removes most of the effort that went into making it a good steak. It would taste about the same as a $5 steak from Safeway. But if you like the taste, by all means buy those $5 steaks and make them black. Just don't waste your money on expensive meat.One big difference: [All chicken you buy in the US is likely infected with salmonella while we do not allow beef to be sold that is tainted with e. coli]. So eating rare chicken will likely make you sick while eating rare beef should, if properly checked, be benign. Well done beef is usually very tough and a lot of the flavor that comes from the "juices" is gone, because the juices have evaporated. A properly cooked rare/medium rare steak is very tender and juicy. That means it feels like it is melting in your mouth and is a lot more flavorful. However, you shouldn't feel pressured to eat steak any other way than the way you want!One reason restaurants don't like it is because generally people who order well done steaks will say something to the effect of "but I still want it to be juicy." You can't have it both ways. You can either have a juicy steak or a well done steak. When you inevitably complain that the steak you had us burn to a crisp isn't juicy, it's irritating.If you go to a seak house order it 'bleu rare' once. The outside is cooked but anything deeper than 2-3mm is raw with the center cold. Absolutely amazing. Outside has marinade flavor, inside beef flavor. Perfection on a plate |
Why can't the wire between a bomb and the timer just be cut? | Its best to remove or disable the fuse if you can, If you were to remove the fuse basically its just as effective as a kitchen timer. This wont work for dirty bombs, you'll just die. |
Why do our bodies waste so much good water when we pee? | Somewhat correct. When we drink too much water, the urine is clear - this is called dilute urine. This is the scenario where we've taken in more than we need and the kidneys filter out the extra, to preserve the balance in the blood. When we don't take in enough, our urine is very dark colored, and this is called concentrate urine. The body actually retains as much water as possible, because it is in rather short supply. Sure your body doesn't know that you'll be in desert tomorrow and retains water today, no animal has a system with such predictive powers. But if you're in a desert today, and your water intake is not optimum, your body will store all the water that it can today to compensate for the short supply. |
How come if fat is stored up excess energy, why can't heavier people do more athletic activities than skinnier people? | Think of a car. Muscles are the engine and fat is the fuel. Give a car a whole trailer full of gas and it won't perform any better even though it has more fuel. Give it a better engine and it will perform better. It's not the amount of fuel that matter but rather the size and power of the engine. Now g |
CNN reporter Chris Cuomo said on air that its illegal for a citizen to study wikileak emails, is this true? | It's not true. Some speculated that he said that because he was a Hillary Clinton supporter and was trying to help kill the story and prevent it from propagating. Others believe he was just misinformed. |
Why can Western Union keep your money without your permission? | Because they're trying to prevent their services from being used for illegal shit. It's the same reason a cop can search you if you're carrying $10,000 in cash. It's suspicious. |
If i am lying in bed with my eyes shut without moving but i'm still awake, can i still get the benefits of being in an actual sleep state? | These are all very interesting comments, I have a question though. Sometimes I force myself into lucid dreams after I've had plenty of sleep, does that kind of sleep count? |
Why do countries like the US and Canada have civilian flights available to Ebola infected countries like Liberia? | Actually Canada has no direct flights to any of the Ebola affected areas. There just isn't enough volume, all would be a two or more stopover flights.A better question would be why do they not quarrantine passengers who board from infected areas for a period of time equal to the typical incubation period of Ebola before allowing them to fly? You see, the sad fact is anyone could be infected with Ebola, pass the immediate temperature check, then later on develop contagious Ebola when they are beyond the natural check points of airports. Why is this sensible policy not being pursued? |
Why is Teddy Roosevelt so revered? | About Roosevelt being the first President to invite a black man, Booker T. Washington, to eat at the White House. Yes, Roosevelt was the first President to invite a black man to dinner, and it was one of the very first things he did, and it was a big deal. Then it became a very big deal. Then it became an enormous deal, and Roosevelt said publicly that he'd dine with Mr. Washington every night he damn well pleased. Then it became a campaign issue. And Roosevelt backed off, and literally never invited another black man to dinner the rest of his Presidency, and became extremely cautious about appearing to favor black people, and so completely distanced himself from all black people that he managed to lose a lot of the goodwill he had earned with them. And then a bizarre racial conflagration called the Brownsville Raid occurred, and Roosevelt so completely mishandled it that he, for one of the first times in the history of the Republican party, shook the faith of the black Republican electorate. The Brownsville Raid is very hard to understand, but long story short, a black soldier in Brownsville, Texas, appears to have accidentally touched a white woman's hat. Two weeks later he _and his entire regiment_ were summarily discharged _without honor_ from the Army, by the personal orders of Roosevelt, who ignored overwhelming evidence that the soldiers never did a thing wrong. It became a defining scandal of his second term and sparked a court battle that lasted for literally seventy years. Black people in America were extremely displeased by the outcome of the case, and Roosevelt lost a lot more friends. |
How does dominos pizza have a single number to call the most local place, while their landline number is much different? | It's not a call center, it's a simple piece of hardware/software that contains a data base and routes based off of the call information coming from the originating local C.O. You point 1 number at the equipment and it does the work. |
Cats are predators. Why are they so skittish? | Cats are *small* predators. Meaning they're not at the top of the food chain, and there are plenty of other animals out there that could in turn predate upon them.Frogs are predators, should one bravely warn off a guy with a gigging stick? |
Why is Google Maps slower now than five years ago? | [Google redesigned the architecture to make it vector based ] Supposedly it'll feel slow for a few years till hardware catches up, or it could just grow bigger with time and stay as slow as it is. As with everything else alphabet the user experience was far better 5 years ago. I don't know what the hell happened in google in the last 5 years but somewhere along the line people who just signed off on shitty user experiences got into senior positions. |
When and why did the image of what is attractive move from a little bit of fat to very low body fat percentage? | It's not just body fat. In the old days, it used to be attractive to be as pale as possible, because being tanned meant you had to labor out in the fields, which meant you had to work. If you were pale, you were inside all day, and were wealthy enough to not work. Nowadays, it's the opposite. Paleness is unattractive to most and it also signifies you're inside working all day. Being tanned is attractive because it means you can lie out on the beach all day. |
What social factors caused Austin, a liberal hipster enclave, to develop in the middle of a highly conservative state? | Believe it or not, there are a lot of liberals in Texas in the current gubernatorial race, Wendy Davis is polling 35-40% not great, but in a state of 26 million, that's a lot of liberal leaning people. So you have Austin, a university town with a progressive music scene, already skewing aware from conservative. If you are a liberal but like Texas, where else are you going to go? And the more liberals who move there, the more appealing it is going to be to other liberals. |
the difference between 32 and 64 bit software | Think of a computer program as having three parts. 1. Workers 2. A Desk to work on, 3. Warehouse space A 32 bit program is like having a 32 by 32 inch work Desk, you can only work on something that will fit on your work desk. A 64 bit program gives you a much larger 64 by 64 inch work desk, so you can work on larger things. The warehouse represents the slow hard-drive, where things you want to work on are stored when the can't fit on the work desk. The workers need to understand that they can use the entire 64 inch desk, otherwise they will only use part of it. |
How exactly do exo suits work? | Basicly, an exo-suit or exo-skeleton is a machine that enhances your strength and other abilities. It doesn't move on its own, but it waits till the user moves. Then it moves with you . This isn't more exhausting than normal, since the suit provides its own power. This way you have more power when moving, since not only do you move, but the suit does as well. Sorry for spelling, mobile phone and not native English speaker. |
Why do beer or soda cans I leave empty on my desk stick to the desk and leave a ring even though nothing was spilled? | I think you're pretty close to the real answer. Somewhere along the line it gets dirty but it dries up. Then, when you take it from the fridge it starts to build condensation, it gets wet, and the dirty stuff on the bottom of the can rubs off. |
Why colonize Mars and not Antarctica? | Because there are no penguins on Mars, so you don't have to worry about PETA showing up and protesting.Did you just watch Waterworld for the first time? |
When a game on Steam is on sale - who gets the smaller cut? Is Steam making less money when something has a discount or is it all on the studio? | I don't know the specifics and can only assume but here goes. Valve takes a regular cut from sales of other parties video games, IIRC it's 35% Now Valve doesn't own the games being sold like say a retailer owns the hard copy, it creates licenses and can distribute these to allow people to play the game on their own service . So Valve shouldn't have to deal with over quantity of stock due to it not selling and thus requiring it to be sold at a lower price to sell more therefore I assume the sales we see on Steam are agreed on between Valve and the publishers of the games such that if a game were to be sold at 50% off, valve would get 35% of that 50% or 17.5% of the non sale price and the publishers would get the rest. As I say I don't know this for certain so maybe someone else has a better answer. |
Why do we salivate and gulp when we are nervous or put on the spot? | My take on it is that your body is preparing to vomit, and that is why the extra saliva is produced. |
Why is the sound of heart beats so unsettling? | In horror movies, when you hear the heart beat there's an implication that the beat is going to stop soon. That creates suspense. |
When knocked unconscious, what bodily function wakes a person back up? What determines when and how quickly it happens? | If anyone wants answers from an experiential point of view, I'm in the unique position to be able to discuss the following phenomena: - syncope due to cerebral hypoxia - traumatic brain injury - concussion - bonus: status cataplecticus! - also conscious sedation and general anesthesia |
The difference between a masters degree, and a bachelors degree | It's two more years of higher level, specialized study. A bachelors degree is four years of general study, with maybe a third of that dedicated to knowledge that is relevant to one particular branch of study, with most of *that* being foundational stuff . |
The mythology of The Legend of Zelda | The most commonly accepted theory, both by fans and developers, is the [Split Timeline theory], in which the time-travel plot of Ocarina of Time creates two Hyrules, one with Link still around as a child and another where Link isn't around, Ganon returns, and Hyrule becomes flooded . That wiki pages gives a great explaination. |
Why didn't the US experience hyperinflation that many economists and politicians said was going to happen when the FED did its quantitative easing during the Great Recession? | The issue with quantitative easing is that it devalues investment in the nation, so it usually becomes more difficult for the government to sell debt. This can have catastrophic results as debt transitions from a reasonable security to worthless paper . However, this did not occur with the U.S. because U.S. remained one of the most stable investments around - in part because the alternatives were so bad. There is also a reasonable suspicion that the U.S. is 'too big to fail' - the sort of economic catastrophe that would result from U.S. debt becoming devalued would consume the world's economic system.Short answer: Because basic economic theory said that it wouldn't happen and the people who said so were cranks. Longer answer: Monetary policy is a good check on inflation and the Fed would have stopped QE and began to curb inflation if it ever got out of hand. However, the conditions were such that the significant increase in the monetary base wouldn't cause inflation. ELI5 the basic economics I mentioned: The Fed did all this while interest rates were at 0, which meant that adding money to the economy wouldn't cause inflation it normally would because the "demand" for money was so high that interest rates, which for ELI5 is a prerequisite for large inflation, wouldn't rise above 0. |
If photons are particles, how can they pass through solid objects i.e. the outer glass of a lightbulb, or even skin? | Thanks all for the helpful comments! I had been racking my brain for a while and just couldn't make sense of it. |
If we came into contact with aliens, how would we actually speak to one another with our different languages? | Something like Pythagorean's Theorem would be a universal concept assuming communication was at least visual, you could draw a triangle with sides 3, 4, 5 that would be fairly simple for anyone to understand graphically. Perhaps a diagram of our solar system, indicating Earth in orbit, demonstrates that we understand our place in the cosmos. etc.In the movie contact, they used math as a universal language to associate true / false to symbols and went from there. |
How does it hurt someone to be over-qualified for a job? | It's hard taking direction from someone who has less qualifications than yourself. Seen this many times. Doesn't matter what your intent is, if you know how to do something, and someone with no clue is trying to tell you different, well it's hard to be the good employee. But if it's a different field it's often not a problem. I know PhDs who are getting their teaching certificate for example. This sort of thing is often encouraged.if over qualified people took jobs they were overqualified for, qualified people would not be able to get jobs at their level. and what everyone else has been saying. this being said, you dont have a legal obligation to tell employers you have a PhD.Over qualification is one thing, the excuse I've been given is that the higher your qualifications, higher are your salary expectations. Not all companies can afford to have PhDs for lower level jobs because they'd want double the money . |
How were candy flavors like apple and cherry created when they taste nothing like an actual apple or cherry? | Inside the fruits there are molecules that our tongues can interpret as tastes. Once you figure out which it is it's just a matter of making it in a lab and testing it. |
How do we know what the Milky Way Galaxy looks like from above and where we are in relation to it? | For a long time, we actually didn't. It was only in the 1990's that astronomers actually began to suspect that the Milky Way was a barred spiral galaxy, rather than a classic spiral galaxy, and this was only confirmed in 2005, by the infrared Spitzer Space Telescope. The reason we couldn't see it beforehand is that there's a lot of dust in the galactic plane obscuring the view - without this the Milky Way would be a lot brighter than it is. |
ELI22: How do I move out of my parent's house? | First of all, where are you living? Can you get good jobs where you are now? Can you work in your field there? How expensive is the cost of living in your area? Most people I know who moved did WAY better in their new location because they were able to pick a place to live that fit with their situation and skills. Moving out of your parents' house may not be enough. You may need to move to a cheaper area or to a place where you can get a better job. 1) Save up a lot of money. Save up way more than you think you will need to move. This may take a while. 2) Find roommates. This may be frustrating and may lead to less-than-perfect living situations, but if you are a mature person and know how to make friends and compromise productively, this should not be a serious problem. Living with roommates will make housing way cheaper and may make you new friends in the process! 3) Teach yourself to live lightly. Learn to cook, shop in cheap places, figure out ways to shave dollars off your current living expenses. Make a budget and stick to it. Be a huge miser. 4) Try to figure out if you can live without a car. If you can, you will save crazy amounts of money. Really the most important thing is figuring out if you need to change cities. |
How do animals know to make eye contact with humans and other animals? | Eye contact is a behaviour that's not unique to humans and in most mammals is a signal for dominance / aggression. |
why does it seem like i lose the ability to hold it in when i reach the restroom? | It's probably a Pavlovian response. You've trained yourself to subconsciously know that the bathroom is where you do your business, so when you walk in, you may suddenly start needing to go, or if you already need to go, the urge will increase. Your body knows it's about to go, so it subconsciously starts letting your bowels go. |
Why do small bugs (gnats etc.) seem to hover around and fly into my eyes far more often than everywhere else on my person? | Selection bias. You see out of your eyes, so of course you're going to notice bugs near your eyes moreso than bugs, say, near your ankles. |
For an older guy who wants to play games, how does steam work? | Steam is a service from which you can buy and trade games via your computer. DLC is downloadable content that requires the game first to use it. First download the Steam client Make an account. Then find whatever game you want through that program. For knowing which games are good: There's reviews sections on each game. Not to mention plenty of websites out there such as metacritic where you can find reviews. If you have any more questions just comment or PM me and I'll answer them to the best of my abilities. |
would I get in trouble for not pulling over if I believed that the person pulling me over was just someone impersonating an officer? What's the protocol if I think such a thing? | Immediately call 911 and ask to verify. You won't get in trouble unless you speed off and try to evade. Drive at normal speed until you get to a public area that's lighted and other people are at. If they ask, you simply explain your precaution. |
why don't police officers drive normal everyday cars as undercover vehicles? Instead of using police cruisers without lights? | I suspect it's because even an undercover cop car should still have the same tweaks that a regular police cruiser does . However, I have seen at least one normal car used as an undercover car. It was some Dodge minivan, maroon, no markings, but it had police lights on the inside. Saw it parked in the streets, lights flashing while the cop arrested some guy in Detroit ). So they do exist, they're just not that common from what I've seen. Most of the time I see black SUVs that look like police cars without any markings, fairly obvious-looking though.There job is also to prevent crime, not just punish. Visible presence helps a lotMe and my brother accidently uncovered an undercover police operation on our road. My brother noticed a vehicle. It was Chevy equinox around a 2011 model. It was DEA creeping with its lights off and my brother thought it was theives trying to case houses. We live out in the county away from crime so things like that stick outSome police need to be available for the public to reach and have an image of law enforcement. If all cops went undercover in normal vehicles, we would not know where to find an officer in an emergency. It is also a deterrent to crime to see their presenceHave you ever noticed how cars will slow down when they see a police officer in a marked car? Fear of being caught and punished is a deterrent. |
if lightning is 5x hotter than the surface of the sun how can people survive being struck? | specific heat. specific heat is the amount of energy it takes to heat something. it takes very little energy to heat air, whereas is takes huge amounts of energy to heat water. a similar thing happens with sparks. an individual spark is hotter than the sun, but it has so little mass that there is very little energy in it. that's why they tend to cause, at worst, minor burns when they strike your skin. there simply isn't enough energy in such a tiny thing to seriously hurt you. |
What exactly urges us to press the traffic light crossing button even though we know that it was pressed before? | with older people pushing buttons either repeatedly or harder comes from prior experience with mechanical buttons that had contacts that became worn with age. as they became worn you needed to press then harder or more times to make contact. you see it with touch-screens even though pushing harder doesn't do anything. the traffic light behaviour could be some social artefact from this example, i.e. people did it, others mimicked the behaviour and over time it lost meaning", 'Not absolute sure about that, but: Aren't we just used to press it and do it because we do it always. When it wasn't pressed before we have to do it if it was pressed before it does no harm to do it again. So pressing it might help and will never harm. Although thinking about whether we need to do it or not might sometimes more costly than to just do it anytime, especially when our mind is occupied by really tough stuff like: "What am i cooking to night?"', "It's really hard for people to be in a bad situation and know that there's nothing they can do to improve things. So we invent things for ourselves to do so that we can feel a little bit more in control. Diehard sports fans wear their special t shirts, soldiers rub some lucky object before going into battle, and you press the crosswalk button, even if someone else already has.The lack of feedback. I would suggest that in economies where either there is a countdown timer, or positive feedback a button on either side has been registered, the button-mashing is lower. |
If someone's date of birth is unknown, how do they get a passport or any other kind of identification? | There was a Radio Lab, a podcast, recently talking about a women from a family that had all their kids at home no doctors. She finally left the family when she was 18. But doesn't have a social security number or a birth certificate. She then has a huge legal battle trying to get those |
Why do some man grow red beards? | No one mentioned how many species have different fur colors on the front and back of their bodies. The nose is where the line is drawn between front and back .I am blond, well mostly bald now. So blond and bald. My beard was ferociously red until it started turning gray. Why did I grow a red beard? Because it was the only beard I could grow.I have the same thing, inherited it from the Norwegian side of the family. Doesn't matter if the hair on our heads is brown, black, or blonde. We all grow red beards in my family", 'Can somebody find the thread from like 2 years ago about androgenic hair expression and how it differs with hair on your head. It would be a more complete answer I thinkI am dirty/brownish blonde headed male and my beard gets red in the summer and darker in the winter, and for science, my pubes are brown.my roommate is half thai and half irish. black hair, asian facial structure red beard. he says he's asian from the nose up.I asked this exact question nearly a year ago and it was removed by a mod with the reason of "personal question" -_- |

What would happen if I tried to deposit $1 trillion in the bank? | If it is legitimate, they would likely accept any amount. Routine is probably in the thousands or lower, unless it is a business banking account, then it will just depend upon the size of the business and what is considered normal based on historic deposits. The difference in all of the methods is really the settlement time. Some of these methods will settle faster than others, making your funds ready to use/withdraw. As an interesting follow up question, ask your bank at what point do they start to make you wait before you get your money back. I have seen numerous situations where trying to withdraw more than $1000 can set off all kinds of red flags. In one case, the person was waiting in the bank for 3 hours! r/BTCr/Bitcoin |
"Data" is not a finite resource. How can telecom companies charge for "data use" when it literally is infinite? | Maintaining the entire network that allows you to transmit data is not free. Cables must be laid and maintained, cell towers must be erected and maintained. People must be paid to do that. I think a good analogy is why energy from a solar power plant isn't free. You're really paying for the hardware and service that allows you to do it.Their network hardware can only support a maximum bandwidth at any given time, so if enough people are using it at full speed at the same time, other customers wont be able to use their service. However, they could use the billions they make off their [97% profit] to expand their infrastructure to make this much less of a problem.Because you're willing to pay for it. Its not any more complicated than that. Manufacturing and distribution is only a small part of a price. The biggest component by far of a price is what the buyer is willing to pay.You have a bucket of infinite water. Near the bucket is a spoon. You pay $5 to drink a spoon of water - you are not paying for the water, you are paying for using the spoon to do soThey need to pay the electricity, and salaries of the employees, in order to maintain everything |
Why are there different kinds of income (Interest, capital gains, salaries, etc.)? Why isn't it all just taxed at the same rate? | Because then you would actually be able to do your own taxes and tens of thousands if not more people wouldn't have a job. |
How the hell is the U.S. still allied with Saudi Arabia? And selling them F-35 Joint Strike Fighters regularly? | First of all, the US is not selling the F-35 JSF regularly to them. Not even a little bit. The list of nations that are approved for the F-35/nations that are partnered on the F-35 are: * United Kingdom* Italy* Norway* Denmark* Netherlands* Australia* South Korea* Japan* Turkey* Israel Second of all, despite what people will say about oil, the US isn't Saudi Arabia's #1 oil importer - increasingly, Asian nations are dominating Saudi Arabia's oil purchases. There ARE benefits from this - cheap oil increases economic productivity which benefits the US, which is such a major part of the world economy. The other points are geostrategic in nature: * Saudi Arabia is at the center of the Arabian Peninsula and borders both the Red Sea and the Persian Gulf . Being friends with the country that can easily help you reach/control such areas is important* Saudi Arabia also contains Mecca and Medina, the two holiest cities in Islam, with the two holiest sites in Islam. As a result, Saudi Arabia has a lot of power and sway in the Muslim world and its billion followers. Being friends with the monarchs that have a lot of power over so many people, even if their beliefs are often at odds with ours, is quite beneficial* Saudi Arabia also leads the Gulf nations - UAE, Qatar, Bahrain, Kuwait, etc. - and is increasingly at the center of Arab world affairs. So long as Saudi Arabia and its friends listen to the US, the Arab world as a whole loses a large chunk of the economic power if they go against Saudi and thus American wishes. This was particularly true when the Arab-Israeli Wars were going on, and especially so after Egypt flipped to being aligned with the US . |
How did Elon Musk succeed in not getting stopped by the petrol lobby? | You are setting up an imaginary situation and then asking why it didn't take place. It could be because it never happened?

How do sports commentators have access to such seemingly obscure facts and stats at all times? > | One of the pubs I visit has the pre-match notes made by a commentator for an international rugby match. It's a HUGE hand-written table on a, roughly, A0, piece of paper on which he's recorded everything about the teams, their record over the last few years, notes on anything interesting related to their other matches, then for each player in the squad it has a potted biography with both major and minor facts about each of them and their playing history. Here's an article a slightly different, but similar, approach _URL_0_ |
How does youtube prevent videos of pornography or real death from being uploaded? Are there any notable instances of this happening? | Keep in mind, it's not really about preventing them from being uploaded, but taking them down swiftly. You can't really prevent anything from being uploaded ", 'There was that one time where people kept uploading porn with The Jonas Brothers in the titleThere was this one instance a few years back where a bunch of users from 4chan uploaded porn videos disguised as Jonas Brothers videos. They then proceeded to troll the entire world by typing "im 12 years old and what is this" into the comment section. It even made it all the way to the news. I think the clip is on youtube somewhere', "There is no way to prevent these videos from going up, except for fear of punishment. It is clearly stated in their terms of use that certain materials cannot be uploading and that accounts may be banned for doing such. If a person isn't afraid of that, then there is nothing Youtube can do to prevent it. |
Why is it possible for a number on a pair of dice to be more statistically common to roll then other numbers? | Don't think of the total number. Instead, think of the pairs of numbers. Each pair of numbers is equally likely. So: 1,1 1,2 1,3 1,4 1,5 1,6 2,1 2,2 and so on. Already it should be clear that there is only one of these pairs that adds up to 2. Two pairs add up to 3 . So 3 is more likely than 2. If you do the whole exercise, you'll find that there are more pairs which add up to 7 than any other number. So 7 is the most likely number you will roll with two dice. |
If muscle burns fat, why is it impossible to spot reduce? | Yarr! Yer not alone in askin', and kind strangers have explained: 1. [ELI5: How does your body decide where it takes fat from when you're burning fat? ]1. [ELI5: When you lose weight/fat, how does your body decide where to lose it from? ]1. [ELI5:How does spot reducing not work, if you can just build muscle in the places you want to enhance? ]1. [ELI5: why doesn't spot reduction work when people are trying to lose fat in a problem areas? How does the body decide which fat to use? ]1. [ELI5 How does the body decide which areas of the body to burn fat for fuel? ]1. [Does the part of your body that you exercise affect where you lose fat? ]1. [ELI5: When your body decides to use fat for energy.How does it decide which part of the body the fat should be taken from? ]", 'Muscle doesn't burn fat, your body burns fat - though the more muscle you have, the more energy your body burns. Any time you need energy and you don't have any readily available, your body says "Grab some fat and let's melt it down," but it doesn't pick it from the area that's being worked out the hardest. So if you're running, it's not going to necessarily grab fat from your legs and butt. Where your body burns fat from is dependant on genetics, lifestyle, and a whole lot of other factors, but in general, fat can be pulled from anywhere it's stored in your body to be used as fuel. So spot reduction isn't really possible.Muscles consume calories but they don't just grab them from the closest source. Sugars are removed from the blood and this is not specific to location. |

please: confirmation bias, strawmen, and other things I should know to help me evaluate arguments | One more thing to look out for is motivated reasoning. Humans generally don't look rationally at all the evidence, weigh it objectively and come to a logically conclusion. More often we start with a gut idea of the answer and then seek out confirming evidence and discount anything against it that comes our way. So, when evaluating arguments, evaluate yourself. Do you find yourself nodding along? Stop and ask yourself why. Or are you going down the logical fallacy list looking for one that fits because it something doesn't feel right? Again, stop and ask why. We can't free ourselves of biases, but we can be aware of them and try to compensate, but only if reflect on ourselves and watch ourselves watch the world. |
How does the army/military wash clothes while deployed? | Depends. If they are at let's say camp leather neck they just drop it of and pick it up the next day. When I was deployed I was at a fob without running water so we used 5 gallon buckets and scrub brushes. and hung them out to dry. Which was the worst since sandstorms would come out of nowhere and make your wet clothes muddy |
If sweating is such a vital function; why is antiperspirant not considered harmful? | There are at least 2 classes of antipersparents. 1. Pore blockers. These are your right guards, and underarm sprays. They absorb moisture and form a film on the skin that plugs pores to limit sweat activity. They are also perfumed so that if you do sweat it will mask the odor. 2. Aluminum salts and other astringent solutions. These work by causing the skin pores and sweat glands to constrict and limit the ability of the sweat ducts to produce sweat. They basically prevent the skin they are applied to from sweating, even if washed, for a periods of one or two days. They have no fragrance, and must be applied after cleaning and allowed to dry. Usually before bed. The biggest problem with type 1 is the clogged pores lead to acne and oily skin. They also stain clothing, and the smell can be very strong when applied. The biggest problem with type 2 is that it can irritate the skin and you can't have any broken skin or rashes or it will hurt like hell. Because it is so effective at stopping sweat, a person must be careful not to over apply it or cover too much of their body or they risk getting heat stroke. This is especially dangerous because once applied, you cannot simply wash it off. The effect lasts several days.You spray it on your armpits, not over your entire body. 90% of your skin can still sweat just fine. |
Why do people cover webcams with tapes on laptop?

How are humans aware of someone looking at them? How does it work? | I have a hypotheses. It's a defense system, to allow us to be aware of ourselves being stalked. |
Why does the U.S use the Electoral College instead of a popular vote? | Originally, the Electoral College was created as an independent body that elected the president. There are no federal laws that specify how a member of the College must vote - essentially, it was an elitist system that allowed a small number of people to choose the best president in their opinion. At the time, the popular vote was nothing more than advisory to the College. Of course, as time went on and political participation increased, people didn't like the idea that they had no real say in electing their president. So over time, states created their own rules about who their electors will vote for. As it stands now, most states allocate all of their votes to whoever wins the majority in their state, although a couple allocate their votes proportionately. TL;DR: there's no actual reason anymore; it's an artifact of our Founding Fathers' elitism.For clarification purposes, the VAST majority of elections do use a simple popular vote. Everything but the President, so your House Member and Senators, your Governor, your State Reps and Senators, your local judge, Sheriff, Mayor, and town council. |
How does white milk make yellow/orange cheese? | Most cheese is naturally white. 9 times out of 10 if you see a yellow or orange cheese it's been dyed that way. |
How can a fighter jet, which has a massive combustion engine, refuel mid-air when I'm told not to refuel my sedan with the engine on? | A lot of people don't understand evap emissions controls. So basically, your entire car has sensors everywhere, all designed to do one thing: Make sure you're not releasing excess pollutants. One of these systems controls gasoline fumes, the evaporative emissions controls. Refuelling your car with the engine running will show the system that there is a pressure loss from the fuel tank - triggering a check engine light that you'll have to get cleared. It's the same error that would occur if your gas cap is starting to wear out and can't maintain a seal when closed anymore. Since these sensors only take readings when the car is running, turning the car off means you can refuel without triggering an alarm. Now, in a lot of newer cars, there are different systems for checking the gas cap that don't necessarily use the Check Engine Light. Nowadays, there are even some vehicles that don't even use a gas cap! But in general, it's still a good idea to not leave the car running. In addition, there's still a risk posed by a pump that doesn't shut off correctly. If your car is running, you could theoretically have gas pool beneath a hot pipe and cause the fumes to ignite, or even have fuel overflow the fill port, dribble down the vehicle, and touch a hot pipe, leading to a fire. All of this is highly, highly improbable - almost impossible. But do you really want to be that one in a million person who just happens to be the one who catches on fire? |
If my body produces completely new skin every month or so, why does it still look old and wrinkled? | Because cellular turnover slows as we age. It goes from every 28 or so days in youth, to every 100 days or more by the time we're in our 30's. So it's not a new skin every month anymore - there's dull, sometimes dry skin that's got fine lines and pigmentation from sun damage and pollution clinging on and making things look less than fresh. And that's just the epidermis . Free radicals from UV exposure, poor diet, stress, medications, etc. cause changes to the dermis which mean less collagen and elastin support - causing deeper wrinkles. Kinda like having the boxspring in your bed cave in the mattress would eventually cave in too.It's a copy of a copy. Your "new" cells are copied from the previous set, which were copied from the previous set, ad nauseum. Imagine running anything through a photocopier 100 times, stuff gets lost with each new run. If you could somehow "store" a set of every single cell in your body at 25, you could *reseed* your cells so that they started creating new versions of your 25yr old stuff, and boom you're 25 forever. Edit: this link[this link] explains the DNA loss when cells replicate, causing aging. It has naked mole rats!', "Oversimplified answer: Have you ever made a photocopy of a photocopy of a photocopy? Every level of recursion is imperfect. From one copy to the next, you might not notice, but trace imperfections are transferred over with every new copy. Those imperfections accumulate until you are several copies in, and the black/grey graininess and fuzzy imagery are impossible to overlook. This is more or less how the aging process, how entropy itself, manifests with the human body. I'm sure others might respond with more specific answers, but this is the jist of it.Collagen depletion and free radicals.Increase your anti oxidants internally and externally, also reduce sun rays.
