My point being duke is that physically intensive jobs such as carpentry, bricklaying and other labor intensive jobs also have their own safeguards to prevent these injuries you mentioned. Not completely remove but prevent, the same way that office jobs still impact people's health. They're required to use hats, hard hats, safety glasses, long sleeved clothing, sun screen, steel capped boots, lifting belts etc.

The things you mention do not particularly happen to everyone and even less so since safety standards have improved.
