I have no idea. I've never lost a fight due to the fact I don't have some playground mentality with some stupid code-of-conduct; I'll quite happily kick you in the groin or punch you in the wind-pipe. Then again, every time I've been in a fight I've always surprised people by seeming to go from calm to psychotic-rage-time-now in half a second, because not much of my mood shows on my face, therefore I've won through surprise and dirty-fighting.
I think I'd probably lose a fight with anyone who either regularly fought or did some sort of martial-art to a good degree, but I'd consider myself a tad better than the average person of my experience simply because I know how to hurt someone and I'm not scared to once angry.
Still, I'm hoping to pick up jujitsu from where I left off (aka, the start) and start tae-kwon-do next year for something to do to keep fit, so hopefully I'll be Bruce Lee in a couple of years. Then I'll dig this conversation out of the graveyard of threads, with Youtube videos of me crushing bricks between my thighs with enough force to cause a black hole.
EDIT - Also, I did quite a few years of fencing and have this habit of assuming a sloppy en guarde position when in confrontations, which is pretty much a very basic stance for some martial arts. I used to have fast reactions too from fencing, but it's been way too long now. Still...once the brick-crushing begins...
