When I was about 5, I thought that everyone started out as an "outie". Your belly button was a "turbo boost" button, that would make you run very fast. But you only got to do it once. Once you pressed it, it stayed in, and you were an "innie" for the rest of your life. The strange thing is that I actually have a memory of the time that I "used up" my turbo boost. It must be a false memory, but I spent a lot of time trying to figure out how to make my belly button come back out so that I could run fast again.
