Is there a point to donating blood if you are AB+? Is giving O- blood to an AB+ person just as good as giving AB+ blood to an AB+ person? | There is always a point to donating blood regardless of your blood-type.

If you're AB+ and donate blood you might be helping someone with AB+ instead of them receiving blood from a... |
How come so many companies are updating their terms of service at the same time? | I'm thinking this has to do with FOSTA. The laws regarding internet sites used to be such that if a prostitute was advertising on craigslist , craigslist wouldn't be criminally responsible for the posting . Trump overturned this by enacting the FOSTA-SESTA laws which removes a lot of those safe harbor rules. As a resul... |

How do we keep finding planets in other solar systems while we have trouble determining if we have found all of the planets in our own solar system? | The method for finding exoplanets is best at finding larger and lower orbit planets and requires the telescope to be in the same plane as the planet's orbit. I believe they require three sightings to confirm that a planet exists . Therefore, someone would have to point a telescope at a star for 33 years to confirm some... |
Why have I heard older conservatives tell younger liberals to wait until they're older, then they'll change their mind? | People grow more 'conservative' as they age in a few respects. The most obvious one is that their cultural habits are rooted in their youth. So one day you'll be faced with a scenario where kids are listening to gawd-awful noise and dressing in bizarre way.

If my bathroom scale shows different numbers around the house, which number should I trust? | Don't worry about it, its prob. not that correct anyway.

If you are trying to lose/ga... |
What causes the brain to spaz out and let me chew my tongue/cheek/lip while I'm eating food, even though I'm real good at it after so long? | Not biting your tongue is a learned behavior, like not allowing yourself to tip over while standing.

Just like the fact that sometimes you step wrong and trip or stumble, sometimes you bite when your tongue is in the way. The worst is w... |
Why we (United States) promote freedom in Libya, Egypt, Syria, Iran, but when it comes to Palestine we veto every single fucking time. | US politicians feel that legitimizing Palestine as a state as it is now would make it difficult or impossible for Israel to reclaim the very disputed land it occupies.

Why is it ok to express "Black Pride", "Latino Pride", "Gay Pride", but it is not ok to express "White Pride"? | Historical context.

How do DJs isolate the individual components in a song (e.g. drums or vocals) in order to make a remix? | They most likely don't.

You can't just 'extract' the instrument par... |
How come almost every culture has their own alchohol? Have they ever thought "Hey, alchohol doesn't taste good, let's stick to water" | It's a drug like any other.

Why do businesses still use outdated and vulnerable software even though better, open source solutions are available? | When you run a company that size, the IT department likes to keep everything standardized so it's easy to control.

if companies are liable for false advertising to sell themselves, why aren't political figures? | Imagine what would actually happen if they were. Also sorts of politically motivated lawsuits.

Since everyone needs car insurance to legally drive why is car insurance not nationalized like some people want with medical insurance? | It kinda sorta is in British Columbia, where a Crown Corporation , ICBC, is the government endorsed monopoly for basic car insurance coverage.

That's a problem.Because they keep on buying tickets, its not a one ... |
Can fish stay out of water longer than humans under water? If so, how is this possible? | It's all about oxygen transfer. A human COULD breath liquid if the oxygen content was high enough, in fact we do at the end of our gestation and the deep sea dive gear uses that also. Our lungs are not designed to pull oxygen out of water with average oxygen content, fish and their lungs are. So fish can survive a tad ... |

Why do grey shirts almost always have that weird pattern on them? | I work in color. It's my family's job. We work with retail companies and designers. In my experience greys are some of the most difficult to dye and get level . That may be why a lot of designers choose heathers, it's more easy and consistent. The production team have so many colors and other things to deal with, they ... |

How would menstruation work in zero G? | Ohhhh OP said *menstruation*. I thought he asked about *masturbation.* I was gunna say they're at work and that'd be highly inappropriate, but men should probably wear condom or a sock if the mandatory bathroom work-jerk demands itself. |

Why is the U.S. so divided as a country? Where did the middle go? | Funny, but I was talking to a friend about this yesterday. We are both in the middle, but were wondering why you don't hear about people like us anymore. I think the media is too busy trying to get ratings. Moderates don't make interesting stories. There's not enough drama for today's infotainment news channels. |
why are scissors hard to use if you hold them in the wrong hand? | Yeah, I hope that gave you a bit of insight into our world. It's amazing how many tools have a right-bias and us lefties have to learn to work around that. It's often uncomfortable and for a while ungraceful. I dislike using semi-auto rifles because the ejector port usually flings hot, spent brass across my centerline ... |

Why is self harm not as accepted as things like smoking and drinking? | I haven't self harmed and I am not close to someone that has.

I would assume there is a mental issue that drives someone to self harm bu... |
Why aren't deserts totally covered in solar panels? | Solar technology is relatively new. The amount of energy that you can gain from a single solar panel has nearly doubled over the last 50 years, and the cost per watt has dropped by a factor of about 20.

Why does it take babies such a long time to learn basic motor skills compared to animals that are able to do it close within a month or even as soon as they're born? | Compared to other placental mammals, our babies are born very premature.

So, while newborns do have the reflexes necessary to walk, resources ... |
Why can we not just plant a TON of trees to help reverse the effects of global warming? | We could do that- but where and with who's money? I basically do, do that in my job as a restoration ecologist.

With the sun being 92 million miles away why do locations a few hundred miles from each other on Earth have such different temperatures? | Distance from the sun doesn't matter so much as angle from the sun.

Why a show like the Colbert Report gets a 11:30 to 12 timeslot, and maintains it despite it's popularity, but doesn't move to an earlier, viewer friendly timeslot. | What time would you prefer it run at? The Daily Show/Colbert run at 11/1130 because they want to avoid network prime time shows. At 11/1130, their only real competition going in was the late local news. That's somewhat changed with Conan. |
In a parallel circuit, how do the electrons know which path to take? | As other people have mentioned, electron flow can roughly be modeled as water flowing through a pipe.

Twice as much water is going to go into the bigger pipe, but the water doesn't decide anything. I... |
Why does the government tax you for not having health insurance? | Obamacare is trying to make sure everyone can get health care without paying too much money. Even people who are already very sick.

How have trains managed to stay relevant through the progression of technology? | Well they progressed through technology too. Steam engines aren't relevant at all. Modern trains are using modern techniques. It's really just the ideas of using rails and attaching passive cars to a motorized car that stayed relavent, and it probably always will stay relevant. It's pretty likely that we'll use somethi... |
Why don't we just forgive everyone's debts? | Every checking account you have with a big bank cost the bank about $350 to $450.

Why isn't Feminism called "Equalism" or something, if the whole purpose is to make both men and women equal. Why the 'fem'? | Because women were at the time of feminism's creation, and actually still overwhelmingly are, second-class citizens. It's a socio-political movement that was originally created by women and for women. Something like egalitarianism is just a vague concept, and something that is instead implemented in all sorts of ideolo... |

why as a tenant I am not allowed to keep pets, but children are fine? | You don't tend to leave children unattended in the flat when you're at work. That's when pets cause damage to the property by scratching, biting, peeing and pooing.it's very difficult to put right at the end of tenancy and as much as people who have dogs don't think they leave a smell, they do. In two of my lets I allo... |

why do so many names in anime/manga's have names ending in what sounds like "maru" | It's just how they made words into names. The suffix -emon does the same thing, see e.g. [doraemon] or [goemon]. |
What happens if you break the sound barrier underwater? | It is basically impossible to reach sound speed in water.
