What is your biggest physical fear?

I would have to say that my biggist phsical fear is snakes. I know it seems silly, but I am really afraid of them. I still look away when I seem them on tv. I used to have horrible nightmares about them. They would keep me awake for a long time. I don't really know why I am afraid of them, I have never had any experiance of them. Even now I don't think about them because I don't want to have any nightmares.

So that would have to be my biggest fear. I think that is what the question meant. If not, well, that is how I answered it.

What about you guys?
