19 Common Things Science Hasn’t Figured Out
Whether we want to admit it or not, everyone cries. And while experience has taught us that it's a seemingly natural reaction to being either incredibly sad or incredibly happy, scientists have yet to figure out exactly why that salty discharge pours from our eye sockets when we're feeling emotional. It could be a way to bond with our fellow humans, or a way to alert someone else that something is amiss. But these are all just guesses, as weeping is just one of many everyday behaviors the world's smartest brains still haven't quite cracked the code on yet.
Join editor-in-chief Erin McCarthy as she digs into the science—or lack thereof—of 19 seemingly normal things we do that are a mystery to scientists (you can add sleeping, laughing, and hiccuping to that list, too) with the first edition of our all-new Mental Floss List Show. There's a fancy new set, a fancy new host, and plenty of mind-boggling topics we'll be discussing. So put on your smartypants and check out the full episode below.
