If there's one thing knowing facts about our world helps us with, it's having a better understanding of the context we find ourselves living in.

For more of this junk, here are strange science facts to ponder.

Anyway, that's why I always had a terrible fear of the dentist; they'd give me the normal dose of novocaine, then think I was lying when I said it didn't work. Fun times!
