Bellybutton Use, Removal and Addition

We're all pretty sure we don't need it, that it is a leftover artifact from being a fetus once upon a time.

But some of us wondered if there is some structure on the inside of the bellybutton that keeps organs in place.

This led to a discussion about whether bellybuttons could be removed.  We all figured why not.

Word is that a well known model had hers surgically changed to look more smoothed over to almost appear gone.

How odd would it be to look at a person who doesn't have a bellybutton?

What if it became customary to have one's bellybutton surgically removed at birth?

Then we wondered - could a bellybutton be added to the body?  Um ... probably, at least cosmetically.

If it came into fashion like tattoos or piercings, would you get one?

Or two or three?
