because I've really only had one seriously brick shitting experience in my life.
I will speak for some of the military guys such as my dad and my Uncle though. My dad isn't too bad, he's seen some shit but not what my uncle went through in Vietnam. He's pretty fucked, that guy will rarely even talk about stuff that went down there, because that would mean reliving it momentarily.
I know quite a few people that came back from war with PTSD, and these guys are as hard as it gets. Not at all judging you, just saying you really can't make such assumptions without going through something truly traumatic.
