I'll bust a little toe, sprain an ankle, break my arm, cut myself badly and not even crack. I'll yell and curse till I feel better though
I dunno, maybe it's a natural leftover from early times: you bust something, so you're probably in danger, first things first: gimme that adrenaline and get safe or solve the problem.
Emotional stuff though, that can get to a man, although interestingly, it does seem to come more easily when I'm alone.
Maybe conditioning, yeah, but I don't mind too much really.
