Why have humans created a society in which we put immense pressure on ourselves?	[ "Most of the replies, up to here, talk just about work pressure??? Is that the most important thing? I used to live during the \"communism\" - there was no work related pressure (of course, there were other types of pressure existing in the society), people were guaranteed their work and people were much more relax...

Companies spend billions of dollars to instill that \"need to buy something\" in you, by bombarding you with messages (both overt and subtle) telling you that your value as a person is tied to owning things or \"treating yourself\". > Buy this $499 barbecue grill and be the envy of your neighbours! W...
How big would the U.S military have been during World War II without the draft?	[ "The US military was 16 million during WW2 Of those 10 million were drafted.

Was the oxygen level in the past higher than it is now? if so, why?	[ "The presence of oxygen in the atmosphere was extremely low until photosynthesising life evolved, after which came the [great oxygenation event](_URL_0_), which produced things like the banded iron formations, around 2.4 billion years ago.

Why does the amount of bacteria or viruses determine how well your immune system can fight it off?	[ "> Is this like in ancient battles, where the amount of troops plays a crucial role in defeating an enemy army? Sort of like that.

Is jstor's search usually comprehensive enough when it comes to history/humanities journals?" ]
How do shows like Wheel of Fortune and Who Wants to be a Millionaire afford to pay people all of that money every day/week?	[ "A lot of the money comes from advertising. Also, they know that most people won't actually win the million dollars, so they don't actually give out $1,000,000 every show obviously. Also, prizes such as cars are also product placements, which earn them money. So it's largely due to the advertisement. On top of that...

Do we have known examples of "negative evolution"?	[ "I want to point out that this question treats as fact something that is not part of the theory of evolution. It does not have a direction. Evolution is not moving forward toward anything. Mutations are random, and the ones the make a creature better suited to its environment insofar as it is better able to pass th...

Do dreams happen in real-time?	[ "The short answer is we don't know.

The physical actions appear to occur in real-time and match reported dream content." ]	[ "Those kind of fortune telling/horoscope thingys are usually formulated in a very inaccurate way.

Why do we bite our tongue or cheek occasionally when chewing?	[ "We are not perfect. The tolerances are very close. What we chew may throw off the intended motion just as a bump in a road will throw off a skateboarder. If the consequences were more dire, some permanent damage, then probably the action would be less frequent." ]	[ "Part of the presence of pain is its purpose. Your nervous system continues to remind your brain the pain you've experienced so you know to protect it. For us, that means going to a doctor for a broken finger.

What are the actual statistics on what Muslims believe?	[ "Globally, 28% of muslims do not have an issue with suicide bombings, while in the USA, 19% of muslims do not have an issue with suicide bombings.

Why is 10 degrees celsius not exactly twice as warm as 5 degrees celsius?	[ "Because 0c is not the lowest possible temperature.

Why aren't there more assasinations?	[ "Because it's one thing to be angry in an argument and whip out your pistol and another to set up an elaborate plan to kill someone. There's also the \"what if I get caught?\" problem. Living under some president you hate's 'tyranny' for 4 years is better than living in prison for 50 and even if a person thinks a p...

If the expansion of pi is infinite and has been shown to contain every possible sequence of numbers, how can it be non-repeating?

As someone coming from a surveillance and not quite democratic state of China, what is fundamentally bad about mass surveillance if you aren't a criminal?	[ "Lots of people do things that are not illegal but are embarrassing. They have mistresses, or they visit a dominatrix, or they listen to Neil Sedaka records.

Why are feet shaped with curves? Instead of another shape?	[ "If you mean arches, it's because that allows springing, like shocks on a car. That way the joints don't take all the impact of walking. If you're referring to the outline, I think that it's the most functional shape for balance and smooth motion. Like a ball rolling, the feet are less likely to snag on things and ...	[ "Evolutionary response. It's good that feces and rotten fruits look disgusting so you don't eat it and girls are pretty so you make babies with them.

The scientific purpose for crying?	[ "I think I read once that scientists believe that crying evolved as a signal to communicate pain (maybe from being wounded) without making loud noises.

The wikipedia article on gravity states that the speed of gravity is equal to the speed of light.

Quantum nature of light and a mirror - what happens to single photons in contact with a mirror?	[ "The photon is absorbed by an atom in the mirror and its energy is briefly stored in that atom by exciting an electron.

If we aimed a mirror at the night sky, would the light from the stars bounce back and travel for another trillion or so miles?	[ "Yes, it would reflect back towards the star. The light would probably scatter, though, leading to very little light, if any, actually getting back out of the atmosphere." ]	[ "I'll answer the OP since no one else is. Assume we're in space and we are looking perpendicular to the plane of the spinning beam. We'd see a partly transparent disc, getting less transparent as you got closer to the center.

If the ozone layer protects us from ultraviolet radiation, what’s keeping astronauts on the ISS from being overexposed to it?	[ "UV is pretty easy to block. The walls of the ISS will do that just fine. For the rest of the radiation, the ISS is low enough to be within the Van Allen Belts, which blocks the vast majority of the radiation they would otherwise experience in space. The trip to Mars is the bigger problem. Radiation will be an iss...	[ "I wish I had a 5 year old that I could get to pronounce zooxanthellae :) Corals are like tiny farmers that farm tiny plants.

Why does milk, even if heated up, go bad if left out, but baking with milk such as to make cookies or cake not go bad quickly?

When using mineral oil tanks to cool PC components, is it better to expose the cpu die directly to the oil, or leave the layers ( which include thermal pad, metal lid, another pad or paste layer, and then heat sink )?
