I focused on the healing (still do), but I never got good enough to simply embarrass someone in a fight without hurting them. Ving Tsun is my style, and I know more than Broo Lee ever learned practicing that art. My Sifu is 3 generations removed from Ip Man.
If a dumbass has it coming——give it to them. I learned long ago that holding back can get you hurt. Deal with the paperwork later. semper fi
