Ciphergoth, I'm proposing that 5 is another option, not that it should replace the ones he's already proposed. I don't know much about BDSM, but I assume it covers a much wider spectrum than the enjoyment of pain. My main point, which I didn't express clearly enough, is that the term "masochism" is being seriously overloaded in the post. Personally, I can see a connection between spicy food and intellectual challenges (both put me into an excited and forward-moving state, although for propbably different reasons), but horror movies and rollercoasters go into a completely different category (just being scary).
