Why is prostate cancer so common when the prostate is a relatively small organ that is not directly exposed to carcinogens (e.g. UV light, cigarette smoke)?

There is a chance of getting a cancerous cell with every replication. So 'high turnover' organs that replicate...
[ "Cigarettes contain chemical which like tar which cause mutations in DNA. These mutations may cause the cell to turn cancerous. Tar and these other carcinogens are found in minuscule quantities in the air and are therefore not likely to be harmful unless specifically inhaled while smoking or by inhaling cigarette s...

[ "When you carbonate water (H2O), you add carbon dioxide (CO2). This combination allows carbonic acid (H2CO3) to form in the liquid, which changes its flavor. So even when a lot of the CO2 leaves the water as bubbles, some of it is staying in the water long enough to alter its composition and change its flavor as ca...
[ "Some water is \"oxygenated\" from the plant from which it is made. It has extra oxygen atoms suspended in solution. Water doesnt really expire, it more or less goes stale. Its why you have a bubbler in a fish tank. Fish would use up all the oxygen in the water. I know it sounds odd, gasses being suspended in liqui...

The exact response can depend on the allergen and how it enters the body. Hives usually occur from skin contact, runny nose and snee...
[ "Every allergy is just the immune system failing to recognize a foreign body as harmless, or at least thinking that a foreign substance is harmful when it actually isn’t . That‘s why there‘s an inflammatory response if you eat something you’re allergic to; it‘s the same as when your immune system fights bacteria an...

Why is that when we experience a blow to the head we “see stars”?
[ "that's shock, which can result in a rapid lowering of blood pressure, so as to mitigate bleeding out if you were injured. that lowering of blood pressure can make you pass out, or see stars, or essentially feel dazed. It also might have to do with brain injury if the blow was bad enough." ]

How can we distinguish where the sound comes from? Between left and right is really obvious by timing. But between front and back, or up?
[ "The shape of our ears. Our ears are angled slightly foreward meaning that is we can tell front to back, and the ridges in the ear allow us to tell up from down." ]
[ "It can't. It can use mixtures of intensity and delay between speakers to give a 180° degree coverage of sound (from your left to in front of you to your right) but it is impossible for it to make it sound as if it is coming from behind you. What is most likely happening is that it is just playing the audio, and si...

Why do video game console makers lose money from consoles regardless of success and popularity?
[ "Because consoles are almost always sold at a loss. Making and marketing a home video game console is pretty damn expensive, and nobody expects to actually make a profit on the console. The point of the console is to get you into their game/media environment. Because games are basically all profit for the console m...
[ "Games are able to be heavily optimized for consoles since the hardware that will be used is predictable. Allowing upgrades like this would mean that people would have all different varieties of hardware in their consoles, so the games could not be specifically optimized for hardware.

Why does a woman's testosterone level increase after alcohol consumption, but a man's testosterone level decrease?
[ "Men have testicles, women have ovaries. Normal function is reduced by alcohol consumption, and abnormal function is increased." ]

When the estrogen level dramatically drops for menopause, the overall ...

Why do humans not go into heat/a mating season?
[ "We aren't wired that way. In case you haven't noticed our females ovulate (release an egg into the uterus) about once every 30 days or so. We don't have a \"season\" because we're *always in one*. Any month of the year a woman can get pregnant (and they do!)." ]
[ "Because it's not the same blood. Women's bleeding gets rid of the lining of their uterus as part of the menstrual cycle. Animal bleeding happens as a result of the hormone shift when they go into heat, which is called the estrous cycle. Some other primates menstruate like people do, but most don't. edit: seriously...

Why sometimes some coins are worth more than their original value?
[ "Two reasons. First, because, sometimes, the value of the metal in the coin becomes higher than the coin itself. That's why U.S. pennies are not made out of pure copper anymore. Second, and more importantly, because people are interested in coins and collect them. Rarity comes into play. I have a mason jar full of ...
[ "Generally, commodities like gold and silver can be a less volatile market than stocks or currency. However, most of these commercials are scams. Especially for buying coins. The amount of gold they have in them is tiny. like less than $1 worth of gold in a coin that costs $20." ]
