How can we assume that people recycle properly? What happens if someone accidentally throws a non-recyclable item into the recycling?
|
The recycling plant has machines and people to split recycling. Even if it where all recycled properly you still need to put the coke can in the aluminum recycling machine and the coke bottle into the glass recycling machine.

Why when I put my banana in my lunch bag, does everything taste like banana?
|
Whilst I can't really answer your question, have you tried a "banana guard" or similar product? Covering it would reduce contact with the rest of your lunch and protect the fruit from bruising at the same time. I do know that bananas release ethylene as they ripen but according to Wikipedia it is a "colorless flammable gas with a faint 'sweet and musky\' odor when pure". Unlike orange oil which can be found in orange peel, bananas don't contain any banana oil. Amyl acetate, a synthetic chemical commonly called banana oil, actually gets its nickname from the strong banana-like scent, so none can be found in bananas. Taste does have a lot to do with smell though. Perhaps the natural banana smell is enough to make things taste a bit like banana.Your banana farts everywhere! It stinks so much it'll make other fruit soft! Better put that banana in your school lunchbox so it can't fart all over your food.

Would it be possible to change a planet's atmosphere, terrain, etc enough to make it capable of supporting life
|
The process that you are referring to is called Terra forming. Theoretically it would be possible, though at current times, we struggle just to manage maintaining little national parks. The process of changing another planets atmosphere without drastically changing it too much might be more than we could ever manage.Yes. There have been pretty detailed discussions of how to terraform Venus, Mars, and some of Jupiter's moons for Human life. The problem in most cases is the cost - they are almost always immensely complicated and long-term plans . But it's certainly possible, and probably worth doing for our species.Others have answered the plausibility for other planets, but you might not know that this has actually happened on Earth already! The atmosphere of the early Earth did not have oxygen, and when it built up as a result of photosynthetic bacteria , it [killed a big chunk of the life on Earth].

Where do Syrians get their weapons? And why do they still get them?
|
Many of the weapons spread throughout Africa and the Middle East are remnants of the collapse of the U.S.S.R. There were so many spread throughout the region that when it fell many of the weapons ended up on the black market etc. That is one reason you see so many with AK's. That and AK's are one of the most reliable weapons. They were built with more mechanical tolerance so they do not jam as easy etc.Other than what GearnTheDwarf mentioned, some governments do also donate weapons to a side; some European nations have sneakily been donating modern rifles, etc to the rebels, and Russia has been openly selling weapons systems to the Syrian government. Also, as rebel forces kill government forces , the rebels would typically gain the weapons those forces were using.

Why do Energy Drinks only come in cans while water only comes in bottles, yet pop/soda can go either way?
|
Having worked in the Soda industry, I remember asking once why Soda bottles expired a lot quicker than soda in cans, and it's due to the plastic deteriorating due to the acid in the beverages. There are a few Energy drinks that come in the plastic bottles, NOS comes to mind, however I'm willing to wager that the gut rot we get from the stronger energy drinks works very much the same on the plastic bottles. By putting them in the metal cans it would essentially help increase the shelf life of the product.Nz has both, one of our major energy drinks comes in cans, glass bottles and recently in plastic bottles.

Why does it seem that anywhere you go these days , there is background music playing (gas stations , malls , airplanes) ?
|
It's mostly a subconscious thing. There is some evidence to suggest that the tempo of the music playing will affect customers behavior. Slow music in a store might cause some customers to slow down and look around, and possibly even buy more. Fast music in a restaurant might cause diners to eat faster so that the table will be ready sooner. Holiday music might put the customer in a better mood, it might not though.

How are sanctuary cities a thing. Why is it not aganist the law to harbour an illegal
|
It is the federal government's job to enforce immigration law. The states don't need to help out in any way legally speaking. A "sanctuary city" is a city which has an official policy of not helping the federal government, but not obstructing them. If it was illegal to let an illegal alien exist within your city then the federal government would be able to impose duties on state law enforcement, a big legal overreach.

Why are front yard fences generally shorter than back yard fences?
|
Fences are built for many reasons. Back yard fences are often for privacy and/or protection. Front yard fences are often for decoration and property delineation. Also, many communities have restrictions on the height of front yard fences.

How does washing your hands kill germs?
|
Generally it doesn't, it just moves the germs away. Kinda like washing mud off your hands doesn't destroy the mud, just moves it elsewere. That's with regular soap. Do not use antibacterial soap. Or antibacterial anything for that matter. Getting rid of germs seems logical , but doing that messes up your immune system, causes allergies and other health problems. That doesn't mean you should start living like a caveman though, find the balance. source: med school

What is exactly social security?
|
You work, you pay SS. The taxes you pay go to someone else who is receiving SS. When you retire you will be paid by others who currently work. The amount you get paid receiving SS is influenced by the amount of taxes you contributed. SS is facing issues but the worst case scenario is you receive 60-80% what a person would have today. SS you will likely receive less than you pay in if you work a full life time. Medicare is the opposite and most beneficaries receive $2 to $3 for every $1 contributed which will likely be a larger issue than SS funding.

When humans die our bodies rot. When insects die they just dry up. Why?

Their insides rot. But their 'skeleton' is on the outside, and just like humans, it's the hardest part and resists breaking down the longest.

Why is there so much Leprosy in India?
|
First we must consider that India seems to be the origin point of the evolution of leprosy about 2500 years ago. The amount of cases is always highest I around a disease's point of origin. In general, infectious diseases tend to do very well in the warm climate of the tropics. See how malaria remains largely confined to the warm swampy areas? The answer mentioned by /u/arm4da is demonstrably false. Pre-colonial India and China together formed the world's richest region region at the time, with very high cultural sophistication. Yet Leprosy has been high I'm India even in those days. It was termed 'Maha-rog' or 'the Great disease'. Lepers were alienated from Indian society as a form of quarantine. This indicates that Indians were clearly aware of the contagious nature of the disease. Finally, leprosy is a slow disease, taking up to 20 years after infection for symptoms to manifest. It is difficult to detect when a person is infectious. Taking these together, you can see that while there are relatively few cases of leprosy in the world compared to say TB, or malaria, they mostly concentrated around its point of origin in India.

Why is it that our body doesn't prevent us from biting our own tongue?
|
It tries to. Haven't you ever, mid-bite, had that sudden "Uh oh, danger!" feeling - but then it's too late, the deed is done before you could stop it?', "It does. Think about how many times you have bitten your tongue and how many times you haven't.
|
Why do my feet feel sweaty when they get cold?
|
The feeling of cold and the feeling of pressure, combined, confuses your nerves with the feeling of wet. If you were to step onto a coin in after stumbling awake in the middle of the night, you would at first mistake it for stepping in a wet spot.

Why do containers that had egg in them bubble and froth so much, even when just rinsed?
|
Egg whites contain a lot of liquid protein, which forms a thin and strong layer, a temporary membrane that fills with air to make a bubble.

If someone is using a computer to launch DDoS attacks or do other things on the internet, is it possible to see this activity with a program like Fiddler?
|
So I assume you have a computer which you think is participating in a DDoS, and want to load something on that computer to confirm or not. You have the right idea, but I don't think Fiddler is the best tool. For Fiddler to see traffic, the originating application, or attack program has to be configured to flow traffic through Fiddler, and I would think attack programs wouldn't be so configured. What you really want is Wireshark, which is a network sniffing application. It will passively observe all traffic in and out of the machine. Unfortunately, you will need to be knowledgeable and older than 5 to interpret the output as it is fairly complicated. For something easier, I would recommend running a boot time virus scan which would find most problems.

Why is it so difficult to swallow when you look up, or tilt your head backwards?

Because tilting your head back opens your airway and they can't both be open at the same time.

Why are there so many seagulls in the local shopping center parking lot even though I'm nowhere near close to the ocean or a large body of water.
|
Seagull is a common or informal name for many different types birds that are located pretty much everywhere across the planet. The gulls you are seeing are probably ring-billed gulls. They do like to nest near water, but since they can eat pretty much anything, they are commonly found near easy to find food sources.Because they are perfectly content eating people's waste. Something shopping centers are not in short supply of. They also flock around garbage dumps.

How do Governments pay back trillions worth of debts?
|
We are perpetually paying off old debt while creating new debt. Debt is basically the total money the US government owes to people who hold government bonds. These government bonds set out a repayment schedule, and the US has never missed a payment since the revolution making it one of the safest investments on earth. If you buy a $5,000 2 year bond, it means you pay the government $5,000 and over the next 2 years they will pay you back $5,000 plus interest. Bonds are important, they help balance "risk" by being very very safe. In a risky world economy, lots of people want to buy bonds and that means the US has no problem finding buyers without raising interest rates. So government debt does "go away" but it is replaced by new debt at the same time. Even in the 90s when the debt was "going down" we were still creating new debt, just not as fast as we were paying off old debt.They pay them out over time. A lot of debt is held in bonds that is to be repaid a couple years down the road. Because a countries lifespan is theoretically infinite it can always hold debt and still be in the clear as there won't come a day where it will need to be all collected.

Why do people from SA Asia and Singapore use "LA" in nearly every sentence? What does it means?
|
Singlish is a mixture of local languages with English and used in informal situations. It's most likely from the Malay suffix *-lah* which makes a verb into a command so it's the imperative. So, if you go out with people and get your food but the waiter has to get the food of the other people you're with, somebody might say "eat lah" meaning that you should start eating. You can also use it if you're impatient. Like, your girlfriend / boyfriend is taking forever in the bath so you 'd say "hurry up lah" It's also used to give more impact to your statements. Like, a short negative response can be followed by *-lah* indicating that you are really serious with your response. Not that you are serious as in it's a serious situation but that you seriously want to give a negative response. Like, "I really don't know where your wallet is" "don't know lah". It can also be used to strengthen positive things like encouraging your friend in a hard situation. Like, "don't worry lah! It's gonna be fine" Or to curse at people. "Go and die lah!" The thing with Singlish is that it's a really informal language. It's a sign of being educated if you can fluently switch between proper English and Singlish. So, if you speak Singlish, you are probably in a sort of informal situation so it gets a lot of use since you are more likely to use informal speech in such situations.

How do zero calorie energy drinks work?
|
> Is is just that there are chemicals in it that inhibit the neurotransmitters that make you feel tired, or something else along those lines? Yeah, pretty much. Stimulants like Caffeine work by basically telling your brain "you are awake" or blocking the signals that say "you are tired" as opposed to actually giving you energyThey spur your body to consume calories its previously stored. Namely through the use of Caffiene and ginsing among other lesser known herbal compounds. Tangentially, this is part of the ECA weight loss supplement, The C stands for Caffiene> Is is just that there are chemicals in it that inhibit the neurotransmitters that make you feel tired, or something else along those lines? Yes. Caffeine is typically the drug that gives people that "energy". Adenosine accumulates as you get tired, and caffeine blocks adenosine receptors.

A lot of history books talk about the banning of atmospheric tests of thermonuclear weapons in the 60's. Where do they test them now and how is it safer?
|
When they are tested underground there is very little dust kicked up into the atmosphere. When the Soviet Union tested the largest thermonuclear device ever the physicist in charge deliberately did not make it as powerful as possible because the effects would be too wide spread and long lasting.We don't test them anymore. There are international treaties on it, and no one tests nuclear weapons. The only people who have recently is North Korea, and those guys are kinda jerks. But for the most part, we know they work and what they do. Tests arent necessary. Plus they're kinda dangerous.

If a heart is stopped (cardiac arrest), how can a shot of adrenaline sometimes work?
|
If the heart is stopped, you're not going to start it again. A lot of people think that drugs or a defibrillator will start a stopped heart, it won't happen. Epinephrine will cause a slowed heart to speed up as well as increase your breathing rate. It does this by blocking the pancreas' ability to produce insulin and increases the available fat for use as energy around your cells. Together this causes a huge surge of energy. Epinephrine causes smooth muscle to relax, but at the same time contract with more force. So your airway will open, and your heart and arteries will contract with a greater force. All of this basically speeds up the amount of sugar and oxygen that gets to your tissues, reversing the causes of shock. Edit: not sure why I'm getting a few downvotes. I'm a paramedic and kinda know a few things about the question asked.

Why Most Rappers Have the Urge to Say Their Name in Their Music?
|
Educated guess here but in hip-hop it's very common to feature other artists on a track so it helps the artist gain exposure and let's the listener know who's verse or was when they like it. Also worth mentioning that alot of artists don't put the feature artists name on the track. I'm also sure it has something to do with rap music becoming less unique so rappers feel the need to remind us who they are because so many others bite flows/rhyme schemes

what technology exists to help us shoot down and protect ourselves from nuclear missiles, and how effective is it?
|
There are three systems in place by the US. One ship based, that sits near a potential launch site, trying to knock it down as it boosts up, and two land based ones that attempt to intercept the missile later in its flight. None are considered reliable. If anything actually shoots down a missile in a real world scenario, it would be considered a lucky shot. edit: I should point out the defense that is FAR more effective that is in existence and many possess the capability to do. You nuke the F!@# out of your enemy in a massive, targeted first strike on them **before** they can launch any of their missile, and which would likely prevent them from doing so, which also prevents even the chance that you would have to use unreliable defenses, because they ain't shooting nothing back. This was actually a major, and horrifying, tactic both the US and Russia came up with during the cold war, often called a "decapitation strike". Both sides considered this the optimal strategy, and both sides luckily backed down from it

What does it mean when the ingredients of a food product say “natural flavors” ?

|
Why are circuit lines sometimes squiggly?
|
It is so that every lane takes the same time as the others. They are squiggly because those memory components have a shorter distance than others and to have them all run at the same speed, so to get them to run at the same speed as one thats farther away it has to run a larger distance that is equal to the others.The lines all need to be the same length, so some are made squiggly like that. Even though the signals move at near light speed, computers are fast enough now it causes trouble if they aren't all the same length.It is most likely so that all the lines have the same length and the signals arrive at the same time from all the lines to the processor.

From an actual 5 year old; what makes water stick to surfaces?
|
Polarity. The water molecule is unbalanced, and has an attractive field on the molecular level. This very weak magnetism allows it to cling to things. The reason it clings is the same reason why surface tension exists: water likes to cling to other polar molecules. This means that it likes to cling to itself, as well as other materials that are made from polar molecules. The cup is made of polar molecules, which is why water is mildly attracted to the cup.An explanation for a real 5 year old, since I would be impressed with any 5 year old that gets polarity: All liquids are sticky, but some are stickier than others. Honey is *very* sticky, water is not very sticky, but still kind of sticky. Dumping out a cup of honey is really hard, because of its stickiness, and a lot will always be stuck to the glass. Water does the same thing, but less stays stuck to the glass because it is less sticky. The stickiness of a liquid depends on how much individual blobs of the liquid stick together. A cup of water is like a bucket of sand: sand doesn't clump up very much. A cup of honey is more like a bucket of velcro balls or magnets: hard to shake apart. An explanation for a ten year old: All liquid molecules are sort of magnetic . A bucket of weak refrigerator magnets is easier to pour out than a bucket of super-strong rare earth magnets, because the stronger magnets stick to each other more.

theres so many types of toothpaste that supposedly do different things, but they all have the same one active ingredient.
|
There are indeed inactive ingredients that have different benefits, but almost none are significant. The best toothpastes have fluoride, xylitol, no sodium lauryl sulfate. Tom's clean & gentle is a good one, so is Biotene , or Spry/Squigle with fluoride. -dental hygienist.A toothpaste used to reduce temperature sensitivity needs a potassium compound such as potassium chloride, as well as sodium fluoride . But non-active ingredients have an affect on such things as the taste of the toothpaste as well as the appearance, consistency, or amount of foam it produces. None of these things are very important but nonetheless they do influence consumer decisions about which brand to buyThe purpose of toothpaste is to clean your teeth and apply fluoride. Therefore it is both a cosmetic and drug. Drugs are substances that are proven to perform a medical affect/benefit. Here is the definition of of "Active Ingredient" from the FDA: > An active ingredient is any component that provides pharmacological activity or other direct effect in the diagnosis, cure, mitigation, treatment, or prevention of disease, or to affect the structure or any function of the body of man or animals.

What the difference(s) between a pub, a bar, and tavern?

A wise man once told me, "You know what the difference is between smelling shit and eating shit? Parts per million."

Why is my cat obsessed with me after taking a shower?
|
This is an educated guess, but most likely because you have a different smell. Cats have a great sense of smell and identifies other by it, they "know" you because they know your smell and after a shower you are a new "human" that they need to befriend. This is also a reason why if you have two cats and one is taken to vet the other will sometimes hiss at it when you come home, because smell tells it that a "new" cat has come in to their territory.

In these sanctuary cities, Why are the Mayor and city council not being charged with aiding and abetting a criminal, and harboring a fugitive?
|
They aren't actually breaking any laws or aiding and abetting anyone. They're just refusing to do the Federal Government's job for them. It's not up to individual local governments to enforce federal law and they can't be forced to if they don't want to. If they were actively preventing federal officials from entering their cities that would be a different story, but that's not what they are doing.

Before gunpowder weaponry, how were any naval battles fought?
|
A few diffrent ways. I'd recommend /r/askhistorians for a more complete explanation. There's a few things that were done: 1. ramming other boats, either to breach their hull and to sink them, or to send over troops for boarding actions. 2. Archers stationed on deck firing arrows, either regular ones of fire arrows to kill the enemy crew or set their ship alight. 3. Mounted heavy weapons like catapults or ballista's that would fire a vareity of projectiles to damage the enemy ship or set it on fire. anything involving giant parabolic mirrors probably isn't true.

How that tugboat from the front page could pull the ship 10 times it's own size
|
Tug Boats are basically motors with a ship built around them. One big floating motor designed to move ships.Tugboats are slower and aren't very practical in the open ocean, but they can team up, aim better and even pull a larger boat sideways. They sometimes have a lot of power for their little size, but unlike larger boats, they don't need to carry lots of fuel, cargo, people, guidance systems, food, amenities, etc., so they can be just a big engine. Imagine the bigger boat as a bicycle. You ride the bicycle because it does well on roads. It seems to have more power than walking, even though the engine hasn't really changed. However, when you're off your bike, you are more maneuverable. You can make much finer adjustments, and overcome more obstacles. When you park your bike at a bike rack, you don't do it using the bike's driving system - you get off and position it manually, sometimes sliding the wheels sideways and over bumps.

How does muscle enable us to lift heavier things?
|
Muscles are made of fibres which contract to make a certain action. For example, a bicep curl. The more muscle, the more fibres. The more fibres you have contracting together, the more force you create. More force allows you to lift more.

Why do school buses have to always stop before railroads on open up to doors to listen? If the gates are up, it should be clear.
|
Because the gates do not always work, not all rail crossings have gates, and the gates do not always deploy long enough before a train passes for larger slower vehicles to get across should they have some kind of mechanical trouble. This requirement is also for more than school buses. It is required of all buses , and it is required of all trucks hauling hazardous materials.Because what if the sensors that detect an oncoming train has failed? What if the gates are malfunctioning? What if all of this occurs in a blizzard or heavy fog, and the driver can't see the train, an open door lets them hear the train or the horn. There have been plenty of bus vs train accidents to justify the law.

Why do most Christian groups/people align themselves with the Republican party in the USA when the core beliefs of the religion seem to contradict those of the party?
|
While gay marriage and abortion are the wedge issues of today, this alliance predates both being big deals. I mean, gay marriage wasn't even on the table two decades ago. For a long time during the Cold War, Republicans liked to cast Democrats as near-communists, and themselves as the bulwark against those atheist commies. This started building ties in people's minds between party affiliation and religious affiliation, but the big thing that drove southern Christians to the Republican party was desegregation. A Democratic president signed the Civil Rights Act, and the southerners fled the party in response. All the social issues that followed were adopted to energize this bloc in the party and keep them showing up to vote reliably. Edit: As a followup, Catholics were, at one time, reliable Democratic voters, not finding much common cause with evangelical protestants. They were social justice and labor rights voters. The anti-abortion and now anti-birth control platforms have been used to draw the more conservative of this group into the Christian Right, too.

Do certain characters take up more digital memory space?
|
A set of rules for representing characters as data is called a **character encoding**, and there exist a number of different ones, so there isn't one unique answer to this question. Some examples: * The oldest encoding in common use is called ASCII, which takes 7 bits per character. One byte = 8 bits, so ASCII fits in one byte per character. ASCII can encode simple English text, but cannot handle accent marks or other non-English characters in European Latin scripts, much less scripts from outside Western Europe.* There are several 8-bit encodings that extend ASCII with extra characters. For example, [ISO 8859-1], which was designed for Western European languages; it's also one byte per character, but you can't write any character outside the 200+ that it supports.* There are a number of old "multi-byte," variable length encodings that were designed for Asian languages like Chinese, Japanese and Korean. These support ASCII plus one specific language. Since there are so many Chinese characters, one byte per character isn't enough for these. Usually they use a *variable length* system where some characters take more bytes to encode than others.* The modern solution is [Unicode], which is a shared character set that covers as many languages as practical, plus a family of different encodings. The two most common Unicode encodings both use a variable length system: * UTF-8: characters take 1, 2, 3 or 4 bytes. ASCII characters fit in one byte; most non-ASCII alphabets fit in two bytes; common Chinese, Japanese and Korean characters fit in three bytes; very unusual characters take 4 bytes. * UTF-16: characters take 2 or 4 bytes. ASCII, alphabetic and common CJK characters take 2 bytes; very unusual ones take 4 bytes. So there isn't a single answer to your question. In UTF-8 "a" takes one byte, "á" takes two and "人" takes three, but in UTF-16 all three take two bytes. UTF-8 is more common, I 'd say, though.

Why do people chop wood?

It is so that the wood fits into fireplaces, cooking stoves, and so that it is easier to stack in a controlled manner. You do not want a burning log to roll out of a fire so you want to give it at least one flat side.

Why do they remake classic/awesome movies and ruin them? Why don't they take lousy movies and remake them into something good?
|
It's considered too risky. If a production company has a choice between remaking a classic movie that did well or remaking a crappy movie that did poorly, they're going to go with the classic movie because it comes with guaranteed brand recognition. They don't care whether or not the movie turns out to be good, they only want to hype it up enough to get people into the theaters; that's where they make the majority of their money. It's the unfortunate result of an art form that's mostly controlled by people who aren't artists.

It seems that whenever there's a mass shooting, a SWAT team arrives at the scene almost immediately. What are SWAT teams doing when there's no situation for them to be at?
|
Looks like it varies from jurisdiction to jurisdiction, but it seems that they patrol like normal officers, but their gear may be kept in a special truck so they can travel directly to the scene at the same time as their equipment. _URL_0_It depends on each individual agency's SWAT team. I work for an agency that dispatches for 2 separate SWAT teams. Both teams are made up of regular patrol officers with extra training. One team is an urban police department who uses 2 different mobilization types. First they call out all the on duty officers with SWAT training which can put officers on scene in minutes. If the situation is more extensive, they may issue a "full call out" which calls all the off duty SWAT operators to the scene as well. It could be an additional 30-40 minutes until all the off duty operators can assemble and get to the scene. The team is primarily a suburban department who only has one mobilization technique. Their call out calls all the on duty and off duty SWAT operators to the scene. Operators could be coming from all over the county so it could take up to an hour before they can fully assemble. Other agencies might have different call out based on their staffing and needs, but these are the ones I'm personally familiar with. Source: Police dispatcherIn Australia we have whats called SOG which is our equivalent of SWAT. As far as I know they will spend maybe 4 days a week just training. On the other day they will either be on call or assist with search warrants for the Crime Investigation teams. Then again SWAT could be completely different.Most are regular patrol officers with SWAT qualifications. They train a hell of a lot more, but they're doing regular cop stuff until a situation arises. The majority of departments in the country operate this way. Huge department's can afford full-time SWAT teams, but that's definitely not the norm.

Why it is metres per second per second instead of metres per second?
|
10 m/s^2 is an acceleration, not a movement, it means that for every second, it moves 10 meters per second faster. 10 m = length 10 m/s = speed 10 m/s^2 = acceleration', "You're confusing speed with acceleration . An object can't be moving at 10 m/s^2, but it can be accelerating at 10 m/s^2. If it had no speed initially, it would be going 10 m/s after one second, 20 m/s after two seconds, etc.

Do the flags on the presidential limo or other state cars serve a purpose?
|
It means the passenger carries rank in person rather than rank in position for the country whose flag the car flies. In practice, that usually means the head of state, chief of government, secretary of state/foreign minister, and some ambassadors. Immunity is subject to a bunch of different agreements between countries, but rank in person generally carries with it personal inviolability

Why do we instinctively breathe using the top half of our torso when using the abdomen is apparently healthier?
|
It's not actually 'wrong'. You 'use' the top half of your torso because it makes space for your lungs to expand. 'Using' your abdomen means that you are consciously focusing your breathing movements on your diaphragm, which is what actually draws your lungs in and out for you to breathe. This can be healthier because it can compress your lungs more, allowing you to push out more CO2 by emptying out your lungs more and therefore slightly increase the concentration of O2. Using the top half of your torso is intuitive because it allows you to intake more air if necessary , such as when exercising. Your body prioritizes air intake in that situation over a marginal increase in O2/decrease in CO2, because the gas ratios won't matter if you can't actually exchange the gases fast enough. It's intuitive because your body can't switch between reflexive behaviors.I instinctively breathe using my abdomen. My biology teacher told me that men are more likely to use their abdomen to breathe than women, but that athletes noticeably favor abdomen breathing less So my guess is that abdomen breathing is easier, but less efficient.

How do holocaust deniers back up their views when there is so much physical evidence, including eyewitnesses still alive, that it occurred?
|
Keep in mind; this is coming from a jew There are very few people who deny the holocaust completely. The thing that people doubt is the scale at which it happened, and that it was specifically targeted towards jews. They don't trust the official reports, because there's no reason they couldn't have been collectively over-exaggerated to an extreme degree . Holocaust denial isnt looking away from picture evidence with their fingers in their ears, its more a systematic distrust of government data which might or might not be propaganda. I just want to clarify, I do not agree with this in the slightest. I have family that was killed in the holocaust, I have heard some of the stories first hand. But I also think people's arguments should at least be represented correctly

the difference between a scientist and an engineer
|
In general, a scientist tries to push the boundaries of our understanding of things. The engineer puts our understanding of things into practice. As an example, a chemist might try to figure out why two substances react the way they do, while a chemical engineer will try to figure out a way to make a given substance.The best, simplest way of thinking about it is by imagining a production line for information/technology: Scientists-- > Engineers-- > Manufacturers-- > You Scientists: Discover new information Engineers: Figure out how this new information applies to and addresses a problem in the real world. Manufacturers: figure out how to market this new widget You: buy it and use it Often, scientists and engineers dabble in each other's field but this is the general idea.

Why are prostate examinations done by digital penetration of the anus? Doesn't it seem archaic in the 21st century?
|
Believe it or not, the index finger is an extremely sensitive tool in ascertaining the size, shape, nodularity, and "sponginess" of a prostate. Physicians are specifically trained to do this. Plus, it is fairly harmless to insert a finger into the rectum to examine/feel the prostate. Other diagnostic modalities have much more risk of damage, take longer to do, take longer to get results, and are much more expensive. The exam only takes about a minute . Just take a deep breath and think about something else. It's really not that big a deal. Wait until you need a colonoscopy. LOL', "There isn't a compelling reason to use another method. Things like MRIs take expensive machinery that is expensive to maintain. The doctor is already there and has the finger included for no extra charge.

Does it make things worse? It's genuine psychiatric advice that sometimes you just need to feel shitty. Recognizing you're down and experience it is part of being mentally healthy, if you're always running away from unhappiness you're like to become mentally unwell.

Why don't McDonald's, Burger King, KFC, etc. do deliveries in the US?
|
No one would tip the driver. You work for McDonalds, you pay for your own gas/car maintenance. You walk up with a few kids meals and fries which are guaranteed to taste kinda old and soggy, this isn't a whole pizza with special delivery bag that keeps it warm, it isn't a whole meal from a Chinese restaurant, it's greasy, small portioned, tiny pickle in the middle of a sloppily ketchuped bun. You hand it over and they pay with a fiver. Oh, yeah, they expect change. And you're running around town with no tip on low cost items that don't even cover gas. How long before you quit and deliver for Dominoes?", 'I had a KFC near me that delivered for about a year and it was AWESOME. No clue why, or why it later stopped. Dem wingzRecently there was a Taco Bell that delivered in Manhattan. It was listed on the delivery website as "Taco Bell "The Famous One.I'm a college student in Chicago, and BK delivers there. _URL_0_

Why does staring at the sun make me sneeze?
|
Because you have a photic sneeze reflex, which about 20-30% of people have. The mechanism of action is not well understood. It's possible that wires get crossed in your brain, and that the stimulus of bright light makes your brain think there's something in your nose.

Why do grownups throw up less than children?
|
Children are dirty. They don't wash their hands, they're constantly around a bunch of other children that don't wash their hands, they put things in their mouths and generally do everything you're not supposed to do if you want to avoid sickness. They also have developing immune systems that haven't developed antibodies to common illnesses.

What are brackets, with reference to basketball?
|
bracket is used to describe certain types of tournaments, not just basketball. It is the chart that lists who is playing whom, and who the winners will play. It can be filled out with predictions of who will beat whom in advance or it may be filled out as the tournament progresses with the actual winners filled in. tl;dr it is a chart of who plays whom.

Why certain checks expire.
|
All checks expire. It forces people to be prompt about cashing checks. Otherwise, every company could have thousands of dollars of uncashed checks floating around, meaning they have to keep tons of extra money in their checking account just in case. True, most wage workers aren't going to forget to cash a check, but it's certainly possible for a check to fall through the cracks somewhere, get lost, etc. If you do lose a check for 91 days, you are still entitled to the money - you just need to tell the company that you lost the check and need ti reissued. They might be cranky with you, but they will cut a new check.

Why phones can have 8 cores and sometimes more but even most high end computers half only 4 cores.
|
Even sub $200 processors like the i5-8400 now have 6 cores while AMD offers desktop chips with 16 cores/32 threads so part of the answer is that you simply don't know what is in desktop computers these days. Then there is the fact that while phone processors might advertise 8 cores that doesn't mean 8 *equal* cores. A big reason for having multiple cores on phone processors is not for speed but for energy efficiency. Only the core needed for a specific task are powered on while the others are asleep. This leads to specialization with only a few cores being strong general purpose ones like you might expect. Finally there is the issue of what is practical. More cores means more heat and more cost to build. On the desktop there are usually limits on how much of that power can actually be used - most games for example show very little improvement beyond 4 cores . While more cores are useful for some productivity tasks many desktop users aren't taking advantage of that so a chips single thread performance has a much bigger impact on how 'fast' their computer is. This is reflected in processors like Intel's budget i3 line which boasts some extremely respectable single threaded performance but tops out at 4 cores, giving it the maximum bang for the buck for most average users.

Why does mixing lights result in a different color than mixing paint?
|
Mixing light together is simple addition. Adding red light to green light gives you yellow light, add in blue and get white light. Paint, on the other hand, is about absorption and reflection. Yellow paint absorbs blue light, and reflects red and green. Red paint absorbs green and blue light, and reflects red. Mix them together and you get a paint that absorbs blue light, absorbs half of green light and reflects the other half, and reflects red: orange paint.Sources of light use what's called an additive color model. Each source adds new wavelengths, thus the collective light is the sum of all sources. Thus when you have a red and green light, your eyes are receiving both red and green bands of light. Paints and pigments use a subtractive color model. In this case, the material absorbs some wavelengths and reflects others. No new wavelengths are added. Thus mixing colored paints, it will absorb more colors, causing fewer wavelengths to be reflected back. If mathematically inclined, think of additive sources as a union and substractive pigments as an intersect.

Why is it quieter to pee on the side of the toilet bowl than it is to pee directly on the toilet water
|
Sound waves are literally just movements of the particles that make up a medium . Situation 1: Your liquid stream hits the solid porcelain side of the bowl. There is nowhere for the force of it to go except to spread out in roughly all directions, and it barely "slices" through the air along the edge of the porcelain it's hitting, displacing air perpendicularly as it does so, and thus not moving many air particles hard enough to move other particles to cause one of those air particles to eventually hit your eardrum. & nbsp; Situation 2: Your liquid stream hits the liquid surface of the water, and the force of it carries it into the water, along with a lot of air that it pulls along with it. As that air bubbles back toward the surface, it either A) reaches the surface quickly and "pops" OR B) hits back into the stream of liquid still coming down, which causes even more turbulence and the splitting/joining of lots of bubbles until it's a small patch of water that's almost acting like it's boiling. All of that air and water moving around displaces a *lot* more air as opposed to Situation 1, so more air particles eventually bump into your eardrum and *voila*, louder soundPeeing on the side, you are hitting bowl at an angle which reduces the force with which the steam hits it. Peeing inside the bowl, the stream is hitting water at almost 90 degrees which means that the force is at its greatest. Simple rules of trigonometry.

The whole "registered Republican, Democrat or Independent" thing.
|
When you register to vote, you can choose which political party you want to be affiliated with. Those lists are sent to the party organizations so they can contact you, and in some states they qualify you to vote in the primary elections for those parties. It's mostly just a convenient time to sign up for party membership, since you're already thinking about the voting system. Republican and Democrat aren't the only choices, they're just the only choices that matter. You can register with the Green Party or the American Communist Party or any other party that exists in your state , but other parties aren't ever going to win a presidential election in the current system, so anyone that's not registered Democratic or Republican gets reported as an independent in the media.

How breast and bra sizes work
|
Heed my warning friend! I currently have 5 bras in my bureau. 1 is a 42B, 1 is a 36C, 1 is a 40D, 1 is a 42C, and for shits and giggles 1 is a 38DD. All of these fit me, all are comfortable, and all are different brands. Bra sizing is fucked. I can't just go to a store, find my 'allegedly' correct size, buy it, and expect it to fit. Don't buy your lady a bra. Instead, get a gift certificate to a lingerie boutique , give it to your lady, and eyebrows wiggling with a charming smile ask her to go shopping together on an adventure. Panties. Sploosh. Win.Let’s take an example bra size: 34D The number is the back size; this is the circumference around your rib cage, just under the breasts. The wider you are in this area, the higher the number. The letter is the cup size; this is the size of the breasts, e.g how fatty they are. The letters start with AA which is the smallest, and then they go up the alphabet the bigger the breastsThe number is the circumference around your chest, just below the breasts. The letters are the cup size, and that is going to be proportionate to the number, as 32C cup is smaller than a 36C. Note that there is a lot of variation between bra makers, especially at larger sizes, and not all women fit nicely into those sizing categories. Bra fitting is as much art as science and can get pretty involvedThe number 32-34-36 is circumference of your chest under your breasts. The cup A-B-C is the bra cup. “A” being the smallest going up. Women that appear a different size can at times wear the same size due to breast shape. This is for USA. Idk about other countries.Convert her size to UK if she's larger, it'll be easier to find sizes. For example in UK sizing in a jj in US I'm an m or n I can't remember.

Because you're anthropomorphising them? It's not bravery, you're just thinking about their behaviour in human terms :) **Cockroach:** I'm nocturnal and only come out of my burrow at night. If I can see light it means someone's dug my burrow up so I better escape and hide. **Human interpretation:** Coward! **Ants:** If some large animal is moving around I'm going to go all crazy and run around biting things TO PROTECT THE QUEEN. **Human interpretation:** Berserker. **Flies:** I'm active during the day and I can react so fast I can easily get out of the way of something trying to eat me. **Human interpretation:** Brave! **Moths:** I'm camouflaged, if I don't move they can't see me. **Human interpretation:** Brave!

Why do tea bags say ‘Do Not Microwave’?
|
Because you are doing it wrong! You are supposed to put tea into boiling water all at once, not slowly heat it up with the water. It does taste different that way. EDIT: To be clear, you don't put tea in water while it is still boiling, you bring the water to a boil, let it cool a bit, then put it in.Oy vey. I can't believe so many people are talking about the staples. You can walk over to your microwave right now and prove that wrong. It is how the tea steeps: the volatile flavor compounds in the tea come out from the leaves at different rates depending on the water temperature -- some of them are good, some of them are bad. It's impossible to control the water temperature in a microwave, so you end up with a strange mix of good and bad flavors, in all the wrong proportions. The manufacturers put "do not microwave" because they don't want someone tasting their product, having it taste like crap, and never buying that brand again. [Edit: I 've microwaved tea hundreds of times, and never once seen any evidence of arcing or fire risk. But, to be fair to the folks who have commented, some people have reported that they have seen that.]', "What a time to see this question, I'm at a tea factory in Kerala right now! You're supposed to put the tea in boiling water, not boil tea water. They taste different

Does the Surface Tension of Water change (increase/decrease), as the surface area changes?
|
No but the ratio of the effects of surface area can change as the volume increases. Temperature does affect surface tension. Surface tension is a result of molecules of water forming stronger bonds with other water molecules than with air. Therefore, breaking the surface of the water requires breaking some of those bonds. The bonds between water molecules are weaker when the water molecules move around really fast and spend less time bonded - as in hot water. Once water is boiling, all of the heat energy goes to breaking the water bonds and the surface tension is zero.

How are tracking numbers created and how long will it be until UPS, FedEx and USPS run out?
|
Tracking numbers are randomized numbers and letters, typically in a HexDec system that allows for 16 character numbers, and are typically like in UPS's case, 18 characters long following the 2 character preamble.. This equates to a combination that is as follows: 18^18 = DAMN! or 39,346,408,075,296,537,575,424. That alone give you so many different numbers, that it is impossible to run out of tracking numbers. For USPS, they use a 20 digit Number system with the first 4 numbers predesignated. so 4 + 10^18 = 1000000000000000004. That is exactly 1 Sextillion combinations. Tl;DR; we can track everything. edit for the UPS snob at the bottom.

Does Space Smell Like Anything?
|
apparently space *does* have a distinctive smell, it has been described as being similar to seared steak, hot metal, and welding fumes. > It is hard to describe this smell; it is definitely not the olfactory equivalent to describing the palette sensations of some new food as "tastes like chicken." The best description I can come up with is metallic; a rather pleasant sweet metallic sensation. It reminded me of my college summers where I labored for many hours with an arc welding torch repairing heavy equipment for a small logging outfit. It reminded me of pleasant sweet smelling welding fumes. That is the smell of space. [here] is an article where some astronauts discuss the phenomenon

Why does a candle make smoke when blown out but not when it's lit?
|
The smoke you see is the vaporized wax that is the actual fuel of the candle's flame.The "smoke" is actually fuel, so when the flame is going it is consumed. You can even reignite a candle by touching a flame to the smoke and it will burn back down to the wick.That's not smoke, it's vapourised wax. The wax is still hot enough that it continues to boil for a second after the flame is blown out.

How does magnetic shielding work?
|
A property of magnetism is that it can bend electric fields. So, magnetic shield is used to bend electric fields in such a way that they are largely contained, instead of allowed to propagate freely and potentially cause interferenceThink of it more as a magnetic field conductor. What it does is redirect the magnetic field inwards rather than outwards. Having magnetically shielded speakers/cables would prevent any leakage from adversely affecting your monitor.

What happens to your body when you get winded?
|
You know how walking uphill is harder than walking downhill? Or, how it's more difficult to stretch a spring, and it snaps back to place on its own? For the same reasons, inhaling is more difficult than exhaling. Not so difficult that it requires a lot of effort, but a part of the equation is that empty lungs is your breathing cycles neutral mode. The larger part of the equation is you need to understand what happens when you hold your breath. You know the burning feeling that is telling you to breathe? It's not as much that your body is oxygen-starved, but that it is desperate to expel the carbon dioxide accumulating in your lungs. People get winded because a sudden jolt to the body empties the lungs very quickly. It's a spooky feeling because you stop breathing, but you don't feel like you are suffocating . To begin the breathing cycle again, you need to inhale forcefully because your diaphram is quite content to sit empty. Your normal inhale isn't enough. A person recognizes they aren't breathing, get alarmed, and it's only when they gasp, or start to panic and suck-in hard, that the cycles starts again. It's confusing and jarring.

Why couldn't I rob a bank, serve my jail time, then just have all the money to spend?
|
Judges always file a restitution order. Which means you are required to pay back what you stole.It's illegal to profit from your crimes. You won't get to keep the money, even if you claim it after you've served your time. This law has interesting consequences, such as when a [famous criminal writes an autobiography]. That can be argued as profiting from crime.You do have the answer but I have a better solution for you Why spend years in jail when you can just become a banker, start a shell company in the Caymans and through illegal transactions and stock market manipulation funnel millions down to the "company" in the tropics? Go to early retirement and the money is all pre-laundered for you. You win and still get to be seen as a pillar of the community! *Bonus: If you are a banker and lose the government will cover your losses!*

Why do we shelter kids from what the real world is like instead of teaching them the reality of it?

Why isn't a dimensionless number negligible in a calculation if it theoretically has no physical properties
|
The numbers don't have to have a physical correspondence to nevertheless reflect physical reality. Pi is not negligible, it's a derived ratio. It's required to make the math work. It represents a relationship between certain quantities. That's the whole point of these constants - they were determined based on relationships we understand, and using them is fundamental to making the numbers some out correctly.Suppose I have two loaves of bread, each of which weighs one pound. The "one pound" has a dimension, but the "two" is dimensionless. Nevertheless, it is highly important in calculations. The total weight of two loaves of bread is different from the total weight of one loaf of bread. Or, times is different from times "Dimensionless" does not mean the quantity has no physical significance, it means that the value does not depend on the choice of units used. Suppose you have a spring, and it's 10cm long. That quantity is not dimensionless - you have to specify the unit, and it's not meaningful to say the spring is 10 long. If you measure the spring in inches instead, you get a different number. If you now compress the spring so that it's now 5cm long, then it's 50% of it's original size. Percentages are a *dimensionless quantity* - it doesn't matter what units you use to measure the length - the new length is still 50% of the original length.Dimensionless doesn't mean it's infinitely thin, or weightless, dimensionless means it's simply a number, or a quantity if you will. If you have 3 bars of 2 meters each, 3 is dimensionless. but you certainly can't neglect it if you want to calculate the total length of you bars!

Why is it sometimes easier to remember a word in one's second language?
|
As someone bilingual, I'd say that sometimes some words more accurately represent what you're trying to say in one language than the other. More accurate!", 'For me it is linked to what I am thinking about. I use English a lot for college and I tend to think in English for all the work related stuff. Also: While speaking French I use the Swiss numbers for everything except speed limits and dates for which I use the French version . I have one word I always remembers in English before Danish which is octopus instead of the danish "blæksprutte"', "I get this all the time. I'm no major of anything, but my personal feeling is that it happens especially if you're trying to learn a second language for long periods of time . You try hard to retain it and now that you know the word for it, it sticks in your head and suddenly you forget what it is in your main tongue because you're so occupied by what the word is in the other language.

Why dogs thump their feet when they enjoy getting scratched.
|
it's an involuntary reaction. Kinda like your own patellar reflex (as in when you get tapped on the knee and your leg kicks. It's called the scratch reflex, when something irritates the skin in that area the dog just tries to scratch it. The thought is that it developed as a way to help counter insects and other irritation. Fun fact, vets actually use it to diagnose nerve issues, just like your doctor will see if your leg kicks.

According to people who blame the Jews for killing Jesus--why do they even think that Jesus' death was a bad thing?
|
Because it's an easy justification for being mean to the Jews, which was "in vogue" for about two millennia. Anyway, it isn't really that they *killed* Jesus, it's that they rejected his teachings. As you may or may not know, Jesus was targeted by a group of Jewish religious leaders for spreading what they considered blasphemy, and they turned him over to Pontius Pilate who decided to execute him . The big issue that some Christians have with that is the "considering Jesus's teachings blasphemy" part. If you believe that Christ is the Messiah and Son of God, someone else calling Christ's teachings blasphemy is blasphemous itself, in a weird circular wayTwo points, strictly theology. 1. The death of Jesus is *necessary* in the ideas Christianity, but that doesn't mean it's "good".2. Canonically, Jesus FORGAVE those who killed him, so ignorant Christians who hate or act against anyone for the death of Jesus are in errorAlways found it strange that nobody seems to blame the *Romans*

Why airline tickets in the US are so damn expensive?
|
That's funny. Here in Canada we think of the US as a cheap country for flying. One member of parliament once pointed out that it was cheaper sometimes for him to fly from his home in BC to Singapore than to fly to his workplace in Ottawa.Most of the airlines have struggled to make money as of late, and as a result have taken a lot of steps to cut costs. One of those steps is to significantly reduce the amount of flights they offer. There are very few non-full flights these days. High demand for flights plus reduced demand means higher pricesFuel, Salaries, insurance, and lawyers on retainer if any problem arise with the preceding. Also, convenience.

How do I determine order of atoms
|
I believe we put the less electronegative agents first, followed by the more electronegative ones. Electronegativity is an atom's tendency to attract electrons. So for single atoms, the farther to the right they are, and the higher up, the more electronegative . Oxygen and fluorine are the most electronegative, while atoms like carbon, with four valence electrons, aren't especially eager to give or take electrons.

If I was driving at 100km/h and crashed into a car in front that was going 90km/h, would the impact be equal to crashing into something stationary at 10km/h?
|
Yes, the initial impact would be like 10km/h. However, if the initial impact causes loss of control , the following impact with the scenery will *not* be like 10km/h!It's like they say, "it's not the fall that kills you, it's the sudden stop at the end" So in this case, its not the impact with the car in front of you that will kill you. It's the impact of the cars hitting each other, it's both of you careening out of control off the highway.

Considering all the different elements of sound, how is audio translated into binary so that a computer can understand what it's processing?
|
As complex as sound.. uh.. *sounds*, really your ear drum is interpreting all those various sounds into one wave form. That is because you have one ear drum in each year, and it has only so many dimensions. It's really a matter of how much pressure, and how fast, the ear drum is vibrating. When we first started studying sound, we literally just looked at how our ear drums vibrated, and replicated that with analogue technology. It's just a wave, up and down. So with computers, the binary is just representing that *single* wave. There are a LOT of ways of describing this in binary, depending on how much *fidelity* you want to the actual wave form. Basically, the binary representation will describe in a certain time interval where the wave goes. It goes up, it goes down, it stays flat. So basically / - That's just three little symbols that can represent all of sound.Sound is just a change in pressure that is picked up by our ears and processed. The faster the change is, the higher frequency we hear. With microphone, that pressure is converted into electrical signal and measured many times per second . Since computers do not represent numbers in decimal but in binary, these measurements are saved in a file in binary. When the sound is played, that process is just reversed.Note that on this level, sound properties like frequency, color and intensity are not seen. Frequency corresponds to the speed of pressure change, color depends on how that speed changes over time, and intensity depends on pressure intensity.

Why is fish (or sea food) so much softer than mammal meat?
|
Basically fish have less collagen that attaches muscle to bone because fish don't need the skeleton to support them because they swim in the water every day. Also their muscle fibers are shorter that's why when you eat fully cooked fish you notice the pieces fall apart in consistent chunks.unlike a pig or cow, Fish do not need the amount of muscle to support their weight because they float in water.
|
Why does my skin feel so sensitive and why do my muscles ache when I have a cold?
|
One of the main reasons that your body aches when you are sick, like with a cold is that your body's immmune system is producing plenty of anti-bodies.These anti-bodies also produce histamines which typically dilates blood vessel near an infection, this allows for more of the body's defences to get at the infection. There are histamine receptors in blood vessels that cause them to dilate. As these chemicals are released into your blood stream they can end up in your muscles or other body parts. Various body systems can have receptors to histamine that can then trigger a pain receptor. In addition to histamines there are biochemicals called cytokines that are released when the body has an immune response that are also known to trigger a biochemical pathway that can affect pain receptors.

If cracking your knuckles is pockets of air escaping, how does the air get in and where does it go?
|
It doesn't go anywhere. When you crack your knuckles you stretch out the sacks of fluid that act as cushions but they don't break. Stretching them creates a vacuum inside which pulls any dissolved gasses out. That's the cracking sound, the bubbles just stay inside that sack and eventually dissolve back into the fluid.

How is disney not a monopoly?
|
To be a monopoly, you have to control all of the commerce in your given market. Microsoft was thought to be a monopoly in the past because they controlled ~95% of the PC OS market. Disney is in the entertainment market. Even after the merger, they won't even control 50% of that market, much less the > 75% you really need to have a serious discussion about a company being a monopoly.mo·nop·o·ly məˈnäpəlē/ noun 1. the exclusive possession or control of the supply or trade in a commodity or service. Disney does not have exclusive control of media or entertainment

Who creates the, I assume mostly not real, computer programs we see characters using in films and are they actually functional?
|
I would guess it's just added post production via a cgi program. No reason to write a fake program when all you need is something to just look like a program sense nobody has to use it outside of a scripted scene

If our skin cells are constantly dying and being replaced how do tattoos remain on our skin forever?

> If our skin cells are constantly dying and being replaced how do tattoos remain on our skin forever? The ink is injected *below* the skin that is constantly being sloughed offSkin has three layers. Epidermis , dermis , and subcutaneous . Tattoo ink goes into the dermis.Also, and correct me if I'm wrong, but the ink doesn't affect or alter the skin cells. Instead, the ink is deposited between skin cells. Like dissolving sugar in water. No?

What does it mean it mean to be "in shape" physically, and what does my body actually do if I'm in shape?
|
"In shape" is just another way of saying that you exercise with some regularity and your diet is good; you're not obese. Being too much or too less of anything is detrimental to your health, and being in shape is that balance for someone where they are not obese and scoffing down processed foods 24/7, and it provides your body with loads of good stuff like increased lung capacity, low blood pressure, etc all of the stuff they tell you why you need to exercise. Being "in shape" has no universal standard. For example, I rarely go to the gym, and my primary form of exercise comes from jogging every morning and simply being on my feet for hours every day. . My diet is mainly light foods like fruits/vegetables though I eat a bit of steaks/protein a lot as well. So for me, I consider myself "in shape" because I'm not "fat", I can run a few miles easily, and I eat right for the most part. Someone else might require something different altogether though.
