Ive been laughing at the words "muh ability to heal" all day.
The human body is a complete piece of shit. You could trip on a rock in a desert, break your leg and limp for the rest of your life. I dont know how many people I know irl, who cant do like half the exercises in the gym without immense pain, because of some long ago basic af accident. I cant even imagine the crap you end up with after getting shrapnel or a bullet up your arse.
