Hard tight fist with proper bone alignment, or a relaxed slapping loose strike? Would I rather get hit with a strike from a hammer or a whip? Which would I rather have in my atemi toolbox, and do I really have to choose.
Phi is hella right, I'd rather touch the wife (mine, Phi, not yours, although I am certain she's lovely) than punch out some Joe. I train for life, not live for training.
some of my injuries ached when the weather changed. it reminded me of my youth and stupidity. the question is do you want to destroy your body first in order to learn how to destroy your opponent.
about the wife, i thought i have to go out your way and have a "talk" on touching. but since you mentioned your and not mine, then we are ok.
