The area where I grew up was a mountain region where wood work was the main occupation of most men; even for men that worked in the forest cutting down trees such health problems were very rare, carpenters working in the shops in the village had no such problems. The guy that did the plumbing in my house when I built it was over 70 years old at that time and he was still working because he wanted to be active, even if he could retire at 60 years old by the local law. I find office workers having more health problems than people with some physical activity, sedentarism is a killer.
