Why does lint form in the belly button?

Question

Why isn't it just all over? It all goes right into the belly button.

Answer 1

It comes from inside the belly :)

Answer 2

Probably because its a little hole that can hold onto it... common thing with lots of people with certain kinds of blankets

Answer 3

It seems due to moisture, the clothing particles tend to gather in a very fine layer all over.  When you shower, you clean your body, but not the belly button.  Therefore, it continues to grow in there.

Answer 4

Lint will be caught in any bodily recess in contact with linty clothing, such as between toes.

Answer 5

There was a big debate a couple of years ago in Australia by Dr Karl.

Apparently it's from your underwear travelling up your snail trail.
