I have nothing like "spiders" and "ants", though I have a healthy respect for them (and snakes).
I do have a fear of being hit in the mouth; I lost four baby teeth as a kid, and that never left me. I've played hickey with a broken foot, I've played several sports with broken fingers/arms, but if I fear I'm going to be hit in the mouth, I'm a little coward.
I have a fear of being severely cut, and a fear of losing a limb (not entirely the same thing, but related). I cut my finger on a mandoline a couple months ago and haven't been able to watch one being used on the Food Network since.
It's not a fear, per se, but while I love my mom dearly, I've already told my wife that when my dad passes, all bets are off. I don't know how I'm going to respond but I'm going to need her like no other time. (And no, I don't mean hookers and blow or anything like that, I just mean it's going to hit me very hard).
