I don't have any phobias. Just one generalized terror: the fear of dying, and everyone who ever knew me, or knew of me, also dying. Sadly, that's going to happen. So my worst fear is guaranteed to come to pass. Few other fears are like that. If you're afraid of snakes, you can avoid them: live in a northern climate, don't go to any zoos, and you're good. Fear of death? You'll have to deal with it, sooner or later.
