I did home renovation work for like 8 months. Some of the people in the crew practically destroyed their bodies doing that work for 20+ years. One of the drywall guys would have to use his left hand to loosen his right's grip on the knife because it would get locked up. There was another guy that was maybe 45-55 that walked hunched over like a 90 year old man.
I actually liked the work compared to other jobs I'd had, but the "work through the pain" culture was so toxic. Everyone would act like working hurt was both mandatory and something to be admired.
It's fine to be proud of being a hard worker, but being proud of destroying your body for a boss that wouldn't give a shit if you died is sad.
My best friend as a teen ate burgers by eating the meat and cheese with his bare hands, then eating the bun with ketchup(no other toppings because he and his whole family didn't eat any vegetables). He ate pizza the same way.
