I'm in Australia. I had plenty of fist fights at various school, I didn't get big and strong until late in high school so I took far more beatings than I gave out. Last year of school though, a guy jumped me in class and smashed my face into a desk a couple of times. I'd been doing Tae Kwon Do for a year or two at the time and I knocked him out. Fractured his skull, poor bugger, put him in hospital.
I didn't include weapons but I did get stabbed by my stepfather a couple of times. Also got pretty badly mistreated by a former family friend one afternoon too. Child abuse probably doesn't really count though.
I haven't had any real punch-ups as an adult, but I've stared people down plenty of times, especially late at night on or around public transport. I dunno, I guess my angry face is pretty scary
