8 Surprising Facts

Hey, Vsauce. Michael here...

Coming to you from the Barbican in London. It's beautiful, it's like living inside the Regenstein Library. That's a concrete joke. But, I've put together a leanback of videos all around YouTube that I really like, that I host as a playlist. You can start it by clicking the link at the top of this video's description. It's best if you're on a computer or a laptop, something like that.

But to make it worth your time in this video, I'm going to share some facts I learned this week that were quite surprising and cool. For instance, being attractive might actually mean that you are better, if you play American football. When females were asked to rank the hotness of male American football players, there was a quite surprising correlation. The players that the females ranked as being hotter also tended to be the players with the highest passing ratings.

Passing. Not like passing in a car with a... with a football. But passing in a car brings up the question of gas prices. When gas prices go up, fewer people drive and when fewer people are driving, there are fewer accidents. It's actually quite mathematical. It has been shown that for every 10% increase in the cost of gas, the number of car accidents goes down by 2.3%. Fewer accidents means fewer deaths.

And here's a fact about death. More people have died inside the Halo games than have ever died in real life on Earth, throughout the entire history of humans being around. Killing somebody in real life makes you a murderer. But the definitions of terms like that are very specific. For instance, if you kill four or more people at one time, you're technically considered by the FBI a mass murderer.

And if you kill two or more people, sometimes three or more people, with a time gap in between those events - a cooling down period, you are technically a serial killer. Based on the number of unsolved murders, criminologists estimate that in the United States, at any given time, there are about 100 serial killers who have yet to be caught walking amongst us.

So, keep your eyes peeled or blink if you want to. I mean, the average person blinks 15 times a minute. But when you watch television or YouTube videos, you blink even less frequently - only about 7.5 times a minute. So why blink more often than you have to?
