THe funny thing is, most fights that are hand to hand these days, are stupid... People use most only their hands, they punch in spots that don't hurt too much (shoulders mostly) and think they are the centre of the world...
I've had experience, and let me tell you, well placed punches to the lungs really disarms the person. I have some tae kwon do experience, so I know how to throw my weight into the punch. Of course, you would want to avoid a fight often times, because they might have friends and take it upon themselves to have a 3 on 1... Mind you one of my own fights was a 3 on 1 (me being the one of course), and I came out as the victor, but that is another story.
I'm an introvert... But when I snap, I snap big... XD (Part in parcel of being an introvert I guess). I also like to seeing the victim suffer, especially in a psychological manner... Karma I call it.
** I'm not actually insane :P
