How the heart actually works

It pumps blood. Duh. Well, for most of history, people were unsure what the heart's main function was. Even Leonardo Da Vinci gave up studying it and he's probably one of the five smartest guys ever.

Watch Men Cringe and Cry in Pain As They Go Through a Simulation of…

Women have the ultimate trump card when it comes to dealing with pain: they give birth. And since men have no idea what giving birth even feels like, we really don't know how painful it really is.
