Your Nipples: 20 Facts That Will Make You Perk Up


The human body is a weird, miraculous, beautiful machine, and while many of our body parts have obvious purposes (our heart, our lungs, our stomach), some components are a little stranger to look at, a little harder to understand and a lot weirder to talk about.
