At my old house, there were a lot of garder snakes around, and we'd find snake skin on a regular basis. Anyway, my dad was mowing the grass and he ran over one of those snakes, a whole area in his body was gone, and all that was left of that one area was the skin, gross. He tried putting it out of it's misery, but couldn't behead the thing, the scales were strong.
When I'm flying, and have a bee fly through the center of the circle, I have a half a heart attack but I stay there because I know I'm flying a plane. Bugs are my worst fear, for no reason.
