I have many many things that I dislike doing or being around, but I don't have anything that I really fear in that sense. For me to actually be afraid of something it would require me to care. I, in general, like care and emotion outside of my computer. Some people may think because of that I am afraid of letting people know too much about me(or some such). That's not the case and I answer any personal question they ask. People say heights and spiders. I dislike spiders but understand their worth. Fear of heights is just a natural instinct and understanding that removes it. Fear of being killed? While I would greatly regret dying, when I am dead there isn't much I can do about it so there is no use in worrying about it.
Nothing.
