I think society does a poor job communicating the actual lack of safety that comes from sedentary, physically repetitive jobs.
I wouldn't qualify for workers compensation for my herniated disc because I don't know when it started or why. But it's probably from sitting in front of a computer. Asking coworkers over 35, they almost all have injuries from computer work.
Maintaining weight and strength while a huge chunk of your day is sedentary is a big chore too.
