In all honesty - and without trying to come across like some sort of "tough guy" - I'm not really afraid of much. I've been through, put myself through and seen some pretty gnarly **** and instead of succumbing to fear, I typically just deal with it and face things head on (which will most likely get me killed someday). If I'm faced with something that could potentially "scare" me, I tend to make myself get angry at it - which helps me power right through it.

For whatever reason, I do have a very ridiculous phobia of dropping my keys into a sewer grate/storm drain. So stupid.
