**1. In a room with just 23 people in it, there's a 50% chance two of them share a birthday.**

You might think the odds are 23 out of 365 or something, but nope — it's just over 50%

**2. If you folded a regular piece of notebook paper in half 45 times, it would be thick enough to reach the moon.**

Granted, it's not actually possible to fold a piece of paper in half that many times. But if you could, 45 folds would bring you to the moon. That's the power of exponents, y'all!

**3. Every time you shuffle a deck of cards, you are likely the first person in the history of the universe to create that exact sequence.**

There are 8 x 1067 possible ways to shuffle a deck of cards — that means there are more ways to shuffle a deck than there are atoms on Earth. Most possible card sequences have never been shuffled before, so every time you play Go Fish, you're likely to make history.

**4. It takes just 12 days for a million seconds to pass. But a billion seconds takes almost 32 years.**

**5. One 17-inch pizza is more food than two 12-inch pizzas.**

I'll let you do the math on this one if you don't believe me, but here's a hint: Area = πr2.

**6. You know those dotted lines on the road that separate lanes? Most drivers estimate them to be 2 feet long. In actuality, each of those stripes is 10 FEET LONG.**

Your brain doesn't always interpret geometry correctly! Scientists have attributed this common misconception to a phenomenon known as "size constancy."

**7. What about traffic lights? Yeah, most people don't realize how big those things are, either.**

Size constancy strikes again!

**8. Most people have an above-average number of arms.**

Since some people have no arms or one arm, the average number of arms a person has is somewhere just under two. So if you have two arms, you've got more arms than average.

**9. There's a number out there called Graham's number. It's so large that trying to interpret it might literally turn your brain into a black hole.**

Your brain can only contain so much info, and Graham's number has more digits than any human brain can hold. According to a physicist from the University of California, Irvine, trying to store all of Graham's number in your brain would turn it into a black hole.

**10. There's also a number called a googolplex, which is so large that there's not enough room in the ENTIRE UNIVERSE to write it down.**

There are more digits in a googolplex than there are particles in the whole universe.
