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? Go ahead and click the link at the top of

the description to play the Vsauce Leanback. It's sure to keep your eyes open, because

it's full of videos around the topic of surprise. I'll see you over there, be sure to subscribe

And as always,

thanks for watching.
