Why do western parents have a tradition of kicking out their children when they turn 18 while in Asian cultures, parents often support them at home until they get married? | My family is far from poor, but it was expected I leave home at 18.

Why is an orchestra so big? How can 20 cellos improve the music in a way 5 cellos can't? | It's for balance between the instruments. For example, you only need one snare drum player because he or she can be as loud as all the cellos put together. You need less trumpets because they are louder. You need a lot of strings players because together they balance out the loud and more piercing instruments. If you p... |
Why does soda bottled in glass and cans taste better than soda bottled in plastic? Is there an actual difference or is it all in my head? | There was a difference, when the canning process was not as [refined] > []don't drink canned beer because the aluminum imparts a metallic taste.

Why is eating while watching TV/movies so satisfying? | I think it's kind of simple. While eating, you can't use your hands or mouth.

Why does everybody thank soldiers for what they are doing? | Are you saying you don't thank your accountant?! Sick fuck.At a random hibachi bar, I found myself sharing a table with an army recruiter and his family. As a recruiter, he told me he is required to wear his uniform everywhere. People in the restaurant approached our table regularly to thank him, which he handled well ... |
Why does bread go "soggy" in a microwave, but "crispy" with pretty much every other form of cooking? | It's basically because of fire. Microwaves don't use anything like fire, they just beam heat right into the bread. Pretty much everything else has a direct heat source which works like fire does, causing the bread to get slowly burnt. The difference is that while both transmit heat via [radiation], the non-microwave th... |
If race cars are standardized how can one driver be better than another? | You could say that about anything. Once you master the mechanics and skill of playing guitar, what else is there to learn? But mastering the mechanics and skill of something sufficiently complex isn't easy. |
Why don't we get scanned for EVERYTHING when we go to the doctors? | The reason is simple--it would be very expensive. If you want to have an MRI, x-ray, blood test, urinalysis, etc. every time you go to the doctor, it's going to cost tends of thousands of dollars, either to you or your insurer. It makes a lot more sense to report any symptoms to the doctor and let him be the gatekeeper... |
If a nuclear missile is launched, why can't someone just shoot it down while it is still high in the air? | The thing to realize is that, in an actual nuclear war, there wouldn't be a single nuclear missile launched. There would be *hundreds*, all aimed at different targets . And ICBMs are *fast*. They actually go up out of the atmosphere into a sub-orbital trajectory, and then streak back down at speeds of about 4 miles **p... |
Why does fridge have a "D" in it, but refrigerator doesn't? | bridge", etc. That's purely speculative, of course, but it's at least an educated guess"refrigerator" ultimately came from [Latin *refrigerationem*] .

Who's fighting who in Syria? | Pretty much everyone in Syria is fighting each other and then there is team western powers. Let me explain more. Let's think of this like a wwe triple threat match!

How difficult is it to take an app/game programmed for one OS, and make it compatible for another? Such as Xbox game to Playstation. | Assuming you have the source code and all the tools used to make the original: It's hard to say a definitive answer because it completely depends on the skill and size of the team doing it and how much time they have. Porting between say Xbox One and PS4 isn't that difficult because they are similar machines with perfo... |
Why does the internet at large seem to have a problem with Men's Rights Activists? | Generally men's rights gets tied into the whole rape culture thing which makes it a nightmare.

Why do the people around you always look the same to you, while you can look totally different to yourself even over the course of a few hours? | child", Pizza Guy, Cashier, Sargent literally every title, role, and word that isn't a specific name for an individual is a stereotype.

Why are internet ads (in image form) links to pages that redirect to the advertiser's website instead of just linking to the website directly | The company paying for the add is a lot more interested in people that actually click on the add, as opposed to just those people that see it but don't do anything. They will pay more if the company serving the ads puts the ads in places where people actually click on them. In order to show that, the advertising compan... |
Essential Oils are the new popular thing. Do they actually DO anything? | It depends on the oil. There's no regulation of it so you get a mix of BS and truth.

Why do 401K's exist? | You're a fool for opting out. It's pre-tax retirement savings so the money goes into there before taxes are taken out, and the company matches.

Police officers lying on cases and/or murdering innocent civilians/pets. Is this on the rise? Or the media is reporting it more often? | Homicides committed by civilians outnumber police killings by a factor of 20-30 to one. Furthermore, most killings by police officers are justified, in the sense that the decedent is a violent felon, or otherwise poses a danger. Cases like Michael Brown's are the exception, and even in his case it's not at all clear th... |
How are foods that have been processed in a factory into a finished product cheaper than fresh raw ingredients | A big thing that people always leave out is distribution. There are a few things to consider. I work at a smallish grocery and produce store, and I do orders and inventory. Fresh ingredients are generally large, heavy and wasteful.

why do humans and some animals often rub their cheeks on stuff they "like" or see as "cute" | I tried to ask this same question last week and kept getting modded for it as looking for opinions. Glad someone got it through. It's been bugging me.I'm not an expert in *anything*, but I once listened to a podcast about "cute agression", and what you're talking about may be linked to that in some way. I'm probably go... |
Why do parents urge/force their kids to finish their food? Won't they just eat what their bodies tell them to? | Kids are not always great at understanding what their body wants and needs. The hope is that a nutritionally educated parent will encourage their child to eat appropriate amounts of healthy food - not too little, and not too much.

What does the electric shock therapy do in a mental hospital? | Some doctors discovered that patients who were both epileptic and depressed appeared to feel much better after having seizures.

did playing video games shape my intelligence and personality in a positive way? | Video games have changed in so many ways, so frequently, that it's extremely hard to really measure this.

Brandon Lee (Bruce Lee's son) was killed on set by a bullet accidentally put in a gun. Why would this ever happen? | A series of mistakes.

Unfortunately the did not remove the 'fuse' this is the pa... |
Why are women's only organizations okay but men's only organizations seem to not be okay and don't exist anymore? | You're opening up a whole can of worms asking this question, as a lot of people feel strongly about men's and women's rights one way or the other. As I see it, women's only groups tend to be reactions to spaces women aren't technically barred from, but will be ostracised from regardless through bullying, harassment, po... |
Why it's acceptable to eat meat or hunt certain animals but not animals that are considered typical pets? | I'd say this comes down to two things. First, dietary taboos. Nearly every culture puts some animals off-limits for eating for one reason or another. I'd go so far as to say the tendency to do this is intrinsically human. Sometimes it's just to maintain cultural distinctiveness: sitting down and eating together is also... |

Ayn Rands Philosophy and why it's frowned upon | I've studied and contemplated Ayn Rand's philosophy for over 15 years.

Human beings can gain knowledge about reality only by using reason, wh... |
Why do so many homeless people resort to alcohol and drugs when they are cash strapped? | As a former homeless person, I can tell you boredom plays a big factor for some.

There was one time though when I was very sick and certain I would die within the next couple da... |

If Obama, right before the end of his second term, said "you know what, I'm not leaving." What would happen next? | It would escalate in a series of steps depending upon how adamant Obama was about remaining. First, people would likely think he was joking.

Approximately how wide is Earth’s “orbit zone” and why is this the case? | You just need to move an object fast enough that the centrifugal force counteracts the gravitational force. I don't know if you are familiar with free body diagrams, but you point the gravity vector downward to the earth, and then accelerate it sideways . if you go sideways fast enough you won't fall. Its just like tyi... |
How does repetition of failure lead to improvement? | You usually aren't doing the same thing over any over.

Why isn't there wide variation like with other products? | The magic of smartphones is they work with other devices.

The similarities and differences between the ACA and Canadian or European healthcare systems | They aren't similar at all, really. Here in Canada each province runs its own insurance pool, and everyone is automatically part of it. If you want to go to the doctor or hospital here in Ontario, there is no direct cost.

So the OS loads the programs you're actually using now into memory, and puts the one you haven't used in... |
Why don't Police Departments use unmarked cars that are actually inconspicuous? A 2003 Toyota Camry will get me every time. A Dodge Charger with tinted windows never will. | There are at least two good reasons why. The first is the most obvious: if you're being pulled over by an unmarked car, the occupants might not be police officers. You could be in danger. Since police officers are meant to protect and serve, showing up in a uniformed vehicle that clearly identifies their office command... |
Why must businesses constantly grow? Why can't they just self-sustain? | Sad thing is that unchecked growth is what is wrong with modern economic theory and it should not be a goal of business.

Why does our feet/toes being out of the covers on a bed give people a unnerving sense of dread that no other body part does? | I cannot sleep with my feet covered unless it's very very cold. Then again I can't stand sleeping with any sort of clothes on, and I keep a window open and use only a thin sheet even when it's cold out. Again, unless it's just downright nasty cold. In which case I'll use a tiny fleece blankie but still keep my feet out... |
What is it exactly that alcoholics become addicted to? | Former drinker here. I just liked myself so much more when I was drunk and just felt like something was missing in my life when I was sober.

why do some people with depression lose their appetite and not eat much, while others eat more than usual? | Psychotherapist here. It's very similar to why some people develop binge eating disorder and some develop anorexia; the underlying cause is similar but the coping skill is different.

How can celebrities like Snoop Lion etc be so open about their drug use and not be arrested? | Saying you do a bunch of illegal things is very different from being caught red-handed doing illegal things.

Why is porn not a realistic representation of sex | Porn is for the viewer not the actors, most of the positions they do aren't pleasurable to the actor / actress it is engineered for maximum visuals.

Why are most orchestral pieces string dominated? And why are so many pieces written for that style of orchestra? | Strings have several advantages- one, it's the only family with such consistency from the top of the range to the bottom . Two, it's the family that can produce the widest *variety* of sounds: the steely sound of bowing near the bridge or the fluty sound of bowing over the fingerboard, the hazy sound that results when ... |
The average credit card debt in america is around 7,000 $. As someone from a different culture who was never in debt, how does that happen? | Low pay and a vicious cycleOf predatory lending.

Why people are so outraged when people don't get their children vaccinated. | Kids don't exist in a vacuum, and not all immunity is permanent.

Why are no major drug companies producing medical cannabis. | Uni of Mississippi is currently the grower of all pot allowed for testing in the U.S. The Gov is actually looking for growers at the moment, but you need 20K and a secure facility to even apply for the contract.

How do data collection companies get so much information on individuals? | Accumulation. Steady accumulation combined with most marketing companies having collection done from a very wide net of corporations that hired them for advertising.

Why are cars designed to go over 100mph when most speed limits are 60-75mph? | That's a bit like asking why a bowl was made to be 5 inches high when people only fill it 3 or 4 inches with soup. It won't do a good job at what it's supposed to do without a little extra. |
How is religious LGBT conversion therapy not illegal when it is so patently dangerous for the people involved, and often forced on them? | Provided they aren't breaking other laws, torture, controlled substances, kidnapping, etc., it would fall under of free speech. |

So, that's when the news a... |
Why are MacBooks so overpriced and expensive compared to regular PC laptops? | I think that the demand for MacBooks is relatively inelastic, because they fill a certain niche and are probably aimed at more affluent consumers .

Why can't I live off of supplements? | When I was in graduate school, I was so busy and didn't have enough time, not even to go for my meals.

Your 1500W spac... |
Do animals think cars are other animals? Do they think humans are riding cars like they would a horse or do they understand the concept of man-made machines? | Animals that grow up around roads will know to be aware and wary of vehicles, but cars don't smell like an animal, they don't have faces, they don't display variances in body language etc. I doubt animals see vehicles as alive, but they probably don't see them as explicitly artificial, either - they're just there. It's... |
Why do things burn up upon re-entry into Earths atmosphere (satellites etc.), whereas manned space shuttles do not? | basically, because we build things that are supposed to come back to earth, to survive the trip back to earth.
