How much do you really know about your belly button?

Ah, the belly button. That little point in the middle of your stomach doesn't get much thought. So, what's its deal anyway? Your belly button may not have much of a purpose, but it is your first scar ever that is formed when the umbilical cord is cut when you are born. There are about 1400 different types of bacteria chilling around your belly button. Don't worry, 99.9% of them are harmless. Outies are caused by a tiny umbilical hernia at birth so although they are less common than innies, they are no better or worse. Now you know!
