I've been in a street fight. The guy attacked, I pushed him back, he came again, I tried to hit him over the head with a beer bottle. He parried with his arm, crashing the bottle, then we tangled and rolled around on the ground a bit. Thank God he was just a clueless frat kid, and his ten friends broke us apart, instead of stomping my head in. Lesson learned: Don't leave it on luck for your life and future mobility. Don't get into street fights.
