Diply 14 Feb 2018

Everybody has a belly button, so shouldn't we know more about them? Maybe we can start with the fact that, no, not everybody has a belly button. Sounds wrong, I know, but it's true. We'll get to that.

It's actually a pretty fascinating feature of the human body (and even some non-human bodies have them, too)! Who knew there was so much to know about belly buttons?

1. Most people have an innie.

And no, she's not a secret clone or anything. Mind you, she also hasn't explained her lack of navel, but she's entitled to her privacy. However, some medical conditions, such as an umbilical hernia, can lead to people being born without belly buttons. Many of Karolina's pics have had belly buttons photoshopped in.

Belly hair collects fibers from shirts and directs it to the navel throughout the day, where it collects and builds up into lint. Shaving the hair prevents the lint from collecting.
