I fucked up my back regularly until I'd had enough and started doing a lot of back strengthening exercises, which virtually eliminated the problem. Been doing them ever since. The doc who helped me with this told me that back injuries come from weak backs. You have to specifically work on those muscles to avoid injury.
I found out when waterskiing that you don't get strong waterskiing, you get injured. You have to spend a lot of time in the gym so you don't get injured waterskiing.
Back when I was younger in Seattle, lumberjacking was still a thing. They told me that the limiting thing was injury. They'd work into their sixties. There aren't many jobs harder than lumberjacking. I wouldn't mess with any of them, either, they are freakin' strong and I'm sure they could cleave me from head to toe with a casual swing of the axe.
I'm not in the least surprised that people working in trades mess up their backs, nor do I doubt that they do. But injuring one's back is not the same as wearing it out.
