How can trees live to be thousands of years old? | Plants don't age the way animals do. They may be killed by pests, disease, floods and such, but they don't get weaker over time, so a tree lives until something kills it.

Why does it take more time to release a game on multiple platforms? Why can't people make a game and then immediately release it to multiple different platforms? | Because the platforms literally speak different languages. A made up example might help. To add 2+2 and store that answer as X can happen many different ways. X=2+2 2+2=X Sum=x Set X sum x=Add And that's just a simple 2+2 operation. Actual games are WAY more complicated and contain millions and millions of lines of cod... |

How does Hulu know I use adblock but other sites don't? | What makes you think Google doesn't know? Of course they do, many Youtubers often complain that people use Adblock while watching their videos. And therefore, they don't get any add revenue from these views.

Now if you move your mouse , the ch... |
Why my brain tries to force me to sleep when I get bored. | Maybe because it thinks that you'd make better use of your time sleeping rather than doing nothing or something you consider incredibly unimportant.No tiger around trying to eat you for lunch?

Why can I take 3x100mL bottles of liquid on a plane, but not 1x300mL? | After 9/11 there was the big fear of people bringing on explosives/acceleratns in large quantities.

How would a new traffic law be implemented so that all drivers were aware of it? | If it's a law with major impact, most of the time the news outlets will carry the details.

What are the arguments for lobbying? | Lobbying is the way for any group of constituents to get their opinions and ideas in front of legislators.

Why do mirrors only reverse images horizontally? | They actually don't flip horizontally. They flip front-to-back. It just *seems* to flip left and right because in order for you to face in the opposite direction, you imagine rotating around 180 degrees. But since the image's left side reacts to your left side's motion, it appears to be the left side of a rotated perso... |
Why are spicy foods spicy going in and coming out but not sweet and sour foods? | Rub a hot pepper on your eyeball and you'll find it's hot on every kind of mucous membrane tissue.

Why do professional painters typically wear white, rather than a color that stains less easily? | From what I've been told the most common color of paint in the old days was white.

What is contributing to America's obesity epidemic and how can it be stopped? | The main crops that we subsidize are corn, wheat, rice, and soybeans. It's therefore harder for a farmer to grow other, more nutritionally rounded fruits and vegetables, causing those vegetables to cost more. Low-income people can stretch their paychecks better over worse food because the crops that make those foods ar... |
In the USA, what benefits do small businesses get from the federal government? | I am confused why people need to be a protected class. If I am a business owner, in theory, I own the business and should have the freedom to choose who I sell my product to. Morally, that may not pan out. I may be a closet racist, homophobe. The thing is, why should the government force me to sell to someone I don't w... |
Why do women feel colder than men temperature-wise? | IIRC, it's because of our genitals. Literally. Women need to keep their ovaries warm, so heat is more concentrated to that region, while their extremities get less heat.

It's decent for ... |
Why are there more veteran suicides in this war compared to previous wars? | The fact that there are way less soldiers dying in this war compared to earlier American wars means that there are simply more soldiers walking away that could have suicidal tendencies.

Why don't prisons actually try to make people better? | I'd like to point out that some prisons DO try and rehabilitate people. Norway has [this]. And the cool thing? It works. Of course, it's also expensive, but on the long run, it could balance out . Of course, with countries like the US, bear in mind how many people are in jail for drug possession alone. There's a lot of... |
why is it when you jump straight up you move with the earth, instead of it moving under you. | Put a sticker on a tennis ball. Now spin it around. You'll see that the sticker is moving left to right as fast as the ball. Now imagine looking at the earth from space, and realise that the people are moving around as fast as the earth. Now imagine one person jumps up. Instead of just moving left to right, they're als... |
Why is there such a gap between when a movie is released in theaters and when it becomes available on DVD or BluRay? | Movie releases come in three phases. Phase 1 is your theater release. It comes out and they need to keep it in theater as long as possible. They will delay the release of the DVD if it is popular enough. In the case of Guardians of the Galaxy it will probably be one of Disney's most successful movies ever. It almost be... |
How do bees/wasps instinctively know how to create a perfect hexagon? | Evolution. Bees and wasps don't *instinctively know* how to create hexagons. There's a big difference between *instinct* and *knowledge*, and insects build strictly on the *instinct* aspect of their existence. Flying insect hives are a consequence of hexagonal shapes being ideal in resource cost, structural integrity a... |
If minimum raise is increased how will it benefit those who already have jobs? | If you have a minimum wage job, or anything below the new limit, you'd get a raise. Over a period of time the market should also slowly increase jobs slightly above the minimum wage too to maintain their position as job for slightly better candidates, and that would trickle upwards. The higher minimum wage employees sh... |
What happens to the brain when a bullet goes straight through it. | It depends on the amount of damage the bullet causes. A small caliber round like a .22 will keep most of the brain intact and the brain will go into shock for moment and most likely die shortly after though it's not unheard of for people to survive being shot in the head. However if the round causes a large amount of d... |
Why we haven't taken any images of black holes? | Well we aren't close enough to any black holes to see a good 'disc of blackness' and it's worth noting space is pretty dark anyway, so it'd be hard to make out at the best of times. Would you notice if Jupiter was actually a black spot in the sky? Not easily, and it's a bigger disk than a distant event horizon would pr... |
Why is critical thinking not taught as a standalone, staple subject in the same way maths, English or other subjects are? | In Wales we had a subject called Learning to Learn, which was essentially that. It didn't catch on because you need subject matter to put it in context really |
Why 4-chan and its troll lean so much to the right of the political spectrum | 4chan users may or may not hold those views. A lot of the time, they just want to cause offence. Internet users are typically fairly left leaning for various reasons so they're less likely to be hugely offended by extreme left wing views.

How does Colin Kaepernick kneeling during the national anthem help to draw attention to issues in America? | That act of kneeling is apparently concerning enough that people who approve or disapprove not only do so, but do so openly. And when people are talking about it, they're gonna be talking about why he's doing it. That's why it raises awareness. Even among the people who disapprove of that action, if they recognize that... |
What is the purpose of the puffy ball on top of a winter snow hat? | Weaving in ends is also a not very fun part of knitting and you have an end there. You can use it to tie on the pompom. Granted, making a half decent pompom isn't very fun IMO. The end result is nice but mine always look scrawny and I hate using all that yarn I could be knitting with |
Why are so many US food products not sold overseas, despite the market for them? | It depends on where you live, I guess. If you're used to European sweets and baked goods , American supermarket products may very well turn out to be a disappointment. They were for me, at least. The market for twinkies in a country like Germany, where most people live within walking distance of a bakery or patisserie,... |
- If deadly viruses, like ebola, ultimately kill the host, how do they evolve, or persist to an epidemic level? | Viruses are not intelligent. In fact, they aren't even alive according to most experts. They mindlessly create copies of themselves when they can. To do this, they need materials found inside cells from animals or plants. Not every cell is the same however. Even within a single organism, cells come in a variety of type... |
How does the Billboard Top 100 chart work? How do they decide where songs should debut? | It's an ever-evolving combination of sales, air play, and streaming play. The combination can have some hits jump straight to the top. They have the advantage of coordinated airplay and streaming advertising, which helps drive sales instantly. Sometimes a song will skew heavily towards only one or two out of the three ... |
How dangerous would it be to transfuse blood from a diabetic who has a bad glucose regulation? | A pint of blood isn't going to raise or lower your blood sugar much. You have 8 to 11 pints, so even if you've lost some, it will be diluted, and it was good enough for the diabetic. A little extra sugar will hurt you far less than it hurt the diabetic, and a little too much insulin will just cause your pancreas to red... |
Do supercomputers have similar parameters like ram or hdd size or something entirely different? | Super computers today consist of compute nodes, which are mostly like individual computers. Each node has a number of processors, with a number of cores, and their own RAM, and a couple network cards. There are nodes dedicated to the networking, essentially a switch or router, to ferry work and data to each compute nod... |
Why does one ear randomly go red and hot? | That can actually be a symptom of food allergies. My gf's right ear goes red when she has something with celery in it. They *both* go red when she has pizza . If this happens shortly after eating, and if you have any gastric or ENT symptoms after eating, you may consider allergy testing before it leads to complications... |
Why is it made such a big deal for people to try and eat vegetables with their dinner, but not fruit? | Tomatoes, cucumbers, squash, nearly anything with seeds in it is botanically a fruit, we call them vegetables specificly because they aren't sweet. So the distinction between fruits and vegetables is an arbitrary one based on our preference for where to include sweets in a meal. Veggies with your dinner and fruit for d... |
Why does America arm its police forces when other similar countries such as England, New Zealand and Norway have all proven that its not necessary to do so? | Just a heads up : Our police has been armed since November 2014 because of vague terrorist threats. It might be permanent, but as of right now, it's a still technically/legally a 'temporary' thing.The other countries you mentioned have an extremely different cultural approach to firearms. The Second Amendment grants Am... |
Why many employers hold your first paycheck | Side note: Most of my younger hires or those used to working at places that pay weekly confuse holding a paycheck with getting a later paycheck because of when they started in the pay period. If you come in on week one of a two week pay period and the payday isn't until the Friday 3 weeks out, you're going to work 3 we... |
How does the sushi on those sushi-go-rounds (conveyer belts) stay fresh? They aren't chilled and no where I dine do they look monitored time-wise. | I don't know if every place does it this way, but the conveyor belt sushi by me uses RFID tags to track how long each plate has been out. |
Why are 6-core CPUs rare and why are there no 3, 5, 7 core CPUs? | CPUs are cut out from a round wafer, you want to fit as many CPUs as you can into the die to maximize profit, you do this by making each one a nice even rectangle, and the easiest way to do this is have each core shaped identically and when you add extra cores you add them two at a time. AMD did make a tri-core phenom ... |
It's December 7th. Why isn't Google paying homage to the 75th anniversary of the attack on Pearl Harbor? | Is there a way to do that kind of thing tastefully? I mean, a Google Doodle is the creative use of a corporate logo: is it really appropriate, do you think, to use a corporate logo to commemorate an act of war? Other events that took place on December 7th include: The Great Storm of 1703, the worst windstorm in British... |
Why has Facebook had so much more staying power than MySpace did? | Timing. Facebook's timing corresponded well with smart phones. It gained a foothold in the college market then was able to expand its demographic fairly seamlessly. College kids grew up, started having kids, moving around the country, taking pictures with their smart phones etc. Facebook then expanded the market to all... |
if you are a beekeeper, and your bees fly away, how do you recapture them? | If your bees escape it's usually because they've outgrown their hive . It's likely that they'll swarm somewhere nearby, somewhere structurally supportive, like a tree. In order to recapture the hive, you have to provide a better place for them to live. Beekeeping boxes are usually much nicer for bees than a branch, so ... |
Why the videogame industry does'nt do "remakes"? | There are loads of video game remakes. Maybe not those specific games you mention, but remakes are pretty common. Maybe a larger proportion of films are remakes, but you'd have to look at some hard data to tell if that's true. |
What is the difference between a Chancellor and a President? | Nothing too fundamental. Different traditions, and the actual job responsibilities will vary depending on the institution or the country, but there's not a set of things that chancellors do, and a set of things that presidents do.In universities, for the most part "chancellor" is just a fancy word for "president". In g... |
Why do the American Music Awards not really cover other genres like rock, alternative and metal, instead the whole "rock" genre is mashed together with pop music? | The AMA's have only ever been about pop music by definition and design. Even if you made other categories, all of the musicians that would win would be from pop music. The awards are voted on by fans. Pop music has, by definition, the largest market saturation. Therefore, only pop acts can win an AMA. So even if you th... |
How do stars make gold? | Stars produce gold through fusion, literally fusing two or more atoms into a bigger one. For example if I take 2 hydrogen atoms and shove them together hard enough I can make a single helium atom with some extra energy left over in the form of intense light, heat and various types of radiation. The actual process is a ... |
Why can some people easily sleep sitting up, and for others it's nearly impossible? | Some people will have physiological problems like COPD. They need to sit up to breathe. And, everyone is different. Different likes, spinal curves, noise level requirements, tics, personalities. It all affects sleep. Personally I can fall asleep in pretty much any position, any time, any noise level. And if I don't wan... |
ELI10 why Hitler targeted Jewish people. | For a whole bunch of historical reasons that amount to basic discrimination, the Jews were often hated throughout Europe's history. People disliked them for racial, religious, political, economic, cultural and other reasons. But it all just boils down to humans basically being mean to one-another because they're differ... |
If older cartoons and animated movies were drawn by hand, how did they get the coloring so even and clean, unlike paintings for example? | It all depends on the medium used. For example, paintings often use canvas and acrylic or oils, which tends to be thick and don't evenly mix throughout all the layers an artist applies. For early animators, however, the medium used in earlier animations was often black and colored ink or watercolor, which tends to blen... |
How can bamboo grow up to 3ft per day whereas other plants can get no where near as close to this speed? | It's also not the only plant to grow extremely quickly. [Kudzu can grow up to a foot a day.]", 'Would it be possible to cross bamboo with other type of plants?Its because bamboo, as a grass, can be connected underground to a communal root system. A bamboo "seed" start as a shoot, which are really small and dense. Then ... |
why do hotels never have overhead lights? Stupid lamps don't cut it. | When you look up at the ceiling of your hotel room, what you're actually looking at is the bottom of a 7 inch thick* slab of concrete, which also serves as the floor in the room above yours. These slabs of concrete stretch across the entire floor, on every level of the building, and they're designed to support tens of ... |
Why do different languages have different words for countries? | of the people". More modern, less offensive examples of mismatched names come from sheer mispronunciation due to misalignment of phonemes , from phrase translation , from colonization , from colloquialism outlasting mergers , or from a zillion other reasons -- but they often devolve to people *doing the talking about o... |
Does genetic testing ever reveal good news? | Genetic testing can reveal good news, but you should understand that the vast majority of research and tests in this area are concentrated around health issues because of the major impact they can have on people's lives and because there may be an opportunity to prevent such health problems by knowing about them.

The recent UK vs EU (especially Merkel) conflict? | There are already limits on benefits for EU migrants, and I think more are being introduced. However, people are still concerned that over the long term the migrants will take more than the contribute in taxes . Bear in mind that what people believe about immigration isn't necessarily true. Recently there has been a st... |
Why do we like the type of music that we do? Why do some people like certain genres that other people do not? | People who learn to sing or play an instrument are more likely to enjoy classical music than those who don't.

For someone with no other health issues who is trying to lose weight, why is throwing up after they eat a bad thing? | Many people are touching on the digestive effects of Bulimia, however the more dangerous effect is electrolyte imbalance: Losing that much acid from vomiting that quickly causes a shift in the body's delicate pH level. In an effort to maintain the proper range of pH, the body has to make electrolytes, such as potassium... |
What is it about the brain and consciousness that makes humans so susceptible to religion? | On the whole Religion is a form of Love. The same chemicals that are generated and used by our limbic system for being in Love are the same for when we feel great emotion when seeing images of Jesus, or knowing the joy of communion after a long a fast. At least, that's what I reckon. Putting aside the very real notion ... |
Why is it unhealthy to consume Human Meat and is it still unhealthy if you cook it? | It is unhealthy to consume human meat, both cooked and uncooked. Uncooked:Not only do you have the risks of eating raw meat, but blood-borne diseases/pathogens like HIV can also be transmitted through cannibalism. Cooked:While this will get rid of most of the nasties, prions are still an issue. Prions are screwed up pr... |
Why do MLMs seem to be growing while simultaneously all other purchasing trends are focused on cutting out middlemen (Amazon Prime, Costco, etc.) | I see this too. I also think that 100 years from now, when historians look back on our era and have the cool eye of objectivity to evaluate the wealth-distribution decline we've undergone since the 1990's, the cultural prevalence of get rich quick schemes, MLM and other non-productive sales grifts will be viewed an ind... |
How come foods get crispy after being fried in oil? How come they don't get soggy like if you were to cook it in water? | Water boils at a lower temperature than frying oil does, so when you put food into a fryer, the water boils out, and that's part of what cooks the food. Besides that, after the water boils out the outside can get all crispy and GBD . This is because oil and water don't want to mix together. |
At roughly what age does learning a new skill (an instrument, a language, ect) become more difficult? | I was always taught age 14 is when the neoplasticity of our brains starts to slow. Particularly with language. Which is how baby's pick up on spoken language so well, but drop yourself in Mongolia and you're gonna have a bad time. It's also why kids are being taught a foreign language much earlier in their school caree... |
Why are USA political parties considered more to the right than European or Australian parties? | American political thought and European political thought diverged during the 18th century. American political thought tends to derive almost exclusively from Classical Liberalism and one of the key ideas of classical liberalism is that the government is created by the consent of the people and that its primary purpose... |
Why are crescent moons cut into the doors of old-timey outhouses? | I think it was just to let some light and air in, without exposing you. I know people with outhouses now, and one just doesn't have a door at all. You look out over a lovely creek while you sit there hoping no one else walks up. |
Why does the United States have a disproportionately high number of the top ranked colleges/universities compared to the rest of the world? | Where do you get the 80% from? I'm guessing this number is rather bigger than most lists I've seen. Subjectivity of ranking aside, I'm not quite sure how disproportionate the American dominance is. The US has a huge population and is incredibly rich compared to the rest of the world. It makes sense that country with th... |
Why are papercuts so painful? | People have already mentioned pain receptors and nerve endings and such, but the other reason is the edge that paper has. Take for example, chef's knives. They keep them incredibly sharp, not only to be able to cut food better with, but because it's safer. The sharper the knife, the less force you must exert to make a ... |
Why were lions such a commonly used symbol in the dark/middle ages, when none existed in the nations where they were used? | I think it's similar to the way the neckbearden have pictures of beautiful babes for their avatars although none exist in their basements. |
Why is incest between two consenting adults considered wrong? | The real answer is because if it wasn't you could make a baby and then raise them specifically to have sex with you once they turned 18 and it would be legal. IE its not about 'being gross' but instead about abusing authority the same way its wrong when teachers sleep with their 18 year old students or bosses sleeping ... |
Why do human beings, as a species, get such enjoyment from picking on each other and hurting each others' feelings, even among supposed friends? | We don't all get such enjoyment from it, if everyone got enjoyment from it you'd see it all over the place, most places you go, but most people do have a sensitivity and respect for others. Most people actually get the opposite effect and feel bad when they put others down, everyone has a conscience. I think it comes d... |
how can health professionals tell fairly precisely that a patient will die in the next few hours, days, weeks, months? | Depends entirely on what life-limiting disease is present. The estimate is based on data when we are talking about long-term illnesses. With ALS, the prognosis is 2-5 years and they can narrow it down to the year with decent accuracy. That's just the nature of the disease for almost all people. It's still just a guess ... |
From an unbiased perspective, what exactly do Worker's Unions do? From a biased perspective, why do you think they are good/bad? | I've worked a lot of jobs in my day. Each union job I had paid more then a non-union counterpart. That's all I need to know.Good - they protect the rights of the workers, and generally are able to collectively bargain for a better salary/benefits package than what an in individual would be able to obtain. Bad - The ind... |
Why did humans evolve with such vast differences between individuals' singing abilities? Was this ever a part of natural selection in the se way as looks, intelligence or physical capability? | I don't think this has much to do with evolution, singing is for the most part a skill, not a natural ability, and although some anatomic differences might be more beneficial to singing than others, skill still plays a much larger part. |
Why differing Human races are not considered different species of Human. | There's more to it than this, but part of the criteria that determines a species is the ability to produce fertile offspring. Different species of frog, though they may appear very similar to your eyes, can not mate with each other and produce offspring that can then themselves reproduce. Different 'races' of human can... |
Why do we get bored if we eat the same thing everyday? | People get bored.I don't get bored easily of things and have eaten the same thing for the last 5 months. |
How are sperm cells created, and what are the components of them. How different are sperm cells between people and animals? | I'm actually in developmental biology right now, so this is one of the subjects. Sperm cells are created in the testes from stem cells, which are types of cells that can develop into more specialized cells. These stem cells are guided through development by signals from the nurse cells that encompass them, while some s... |
Why do schools try to find ways to pass and graduate students when they don't deserve it? | Schools get their funding based on the grades. When I moved from a small town to a city my grades dropped sharply. It wasn't until later I found out that, for example, the math taught in the small town was a full year behind. Still is to this day. |
What makes some people "naturally" smarter than others? | I'm sure parents play a role in this when regulating how their child does homework. I like to think that this sets in concrete a work ethic for life. |
Why do they leave the lights on at night when there is no one at school? | In some places, like where I live, it's city by-law to make things easier for emergency responders such as firefighters. |
Why are wild frogs and turtles so trusting towards people? | I've personally never encountered a frog/toad that hasn't desperately tried to squirm out of my hands and hop away. As for turtles/tortoises, if you're not immediately trying to attack their delicate fleshy parts you passed the 'is not a predator' test. |
Why do people generally dislike Piers Morgan? | I don't watch his show, so I don't have any strong feelings about him. From what I have heard from other people, there are two major complaints: 1) Back when he was in the UK, he had a reputation for publishing inaccurate, sensationalist content as news. 2) On his show in the US, he is viewed as arrogant and condescend... |
Why is it more likely to be windy when it's cold? | I'm not sure that it's actually true, but I did a quick Google search and [this website] turned up with a few people discussing your question. |
How are freeways maintained at such a high quality compared to ordinary roads despite considerably more use and less opportunity to make repairs because of traffic? | It's the materials used to meet the demands of the roadway that determine how smooth the road is, but the budget of the overseeing authority determines what they can afford to use. Concrete can withstand heavy loads much better than asphalt, so it tends to be used in freeways that see heavy traffic from heavy trucks. A... |
The TPP, specifically why so many nations would sacrifice their national sovereignty for such an agreement? | A trade agreement is basically an agreement to adopt certain policy stances . When governments adopt these policies anyway to cheat the agreement, lawsuits are the mechanism by which they are corrected. Countries agree to adopt uniform trade policies because it promotes growth. Corporations do frequently try to abuse t... |
Why do two siblings of the same sex, not look exactly the same, even though they have the same parents? | It's like if you rolled two 50 sided dice. And then the total number is the child. The chance of that same number coming up in two or three rolls is very small. And the dice would really have thousands of sides. |
Why do cables have speed limitation? | It's all about foreign signal filtering and main signal attenuation. Phone cable allows a lot of foreign signals to mix plus loses more of the main signal and optical cable is almost immune to foreign signals or main signal loss. |
Twitter and #hashtags. | Thank you all for your explanations. Although I've been a twitter subscriber for a very long time, I never really paid any attention to it. If you stick a pound-sign in front of a keyword, it becomes more easily searchable? When you search, do you include the pound-sign? Or if I want to find stuff about HuckMuffin, tha... |
Why do my tear ducts sometimes make tears that burn my eyes? | I don't know if this is your problem, but with me, it happens at the end of the day, when my naturally oily skin is at its oiliest. When the tears build up more than just enough to moisten my eyes, they are touching/mixing with the oils on the skin around my eyes, and then the oil/tear mixture bugs my eyes. Frequeng fa... |
What trigonometry actually IS? | The number you pass to the sin function is the angle. You're passing a ratio of two sides, which has nothing to do with an angle. If you have a right triangle whose opposite side is 1, and the hypotenuse is 2, then the angle will be 30 degrees. sin is 0.5. On some calculators, the sin function takes radians, not degree... |
When using a debit card, why do some merchants require me to enter a pin, sign a receipt, or simply swipe? | My store doesn't use a pin pad so your debit card is ran through the VISA or MasterCard service. We only require a signature for amounts over $15. Most supermarkets,etc will ask for your PIN on a debit card, or you can skip that step and it'll use the VISA or MasterCard service. Then they have you sign if over a certai... |
