It's hard to say which kind of fact is more mindblowing. Is it the kind that tells us something we never would have imagined, or is it the kind that proves to us that everything we thought we knew is wrong?
It might be hard to put aside what we once believed when we talk about the second ones, but it feels oddly satisfying to tell somebody, "That's a myth, actually." Still, having an actual answer when our friends puzzle over a tough question feels pretty good, too.
Hmm, I'm not sure we'll be able to decide which one is better, but since this list has both, we don't have to. Lucky us!
