They found people in occupations requiring more movement had worse outcomes. But these people are probably also poorer, more stressed, drink more, smoke more. So it's hard to draw conclusions without controlling for this, to state the obvious.

I suspect the compulsory aspect of a job has something to do with it as well. When I injured my wrist, I simply stopped doing exercises that aggravated the pain. This is not really an option for someone whose livelihood depends on such physical activity.

Was going to say that. If it's done as a work, you _must_ do it every day, even when not feeling great, so you may lack adequate time to recover. I think adequate time to recover is the difference between exercise that strengthen us, and physical activity that just grinds us down.

Not to mention that those occupations are far more exposed to all manner of industrial chemicals and often have contempt for the precautions meant to keep them safe.

Just go to any construction site and observe how many are dealing with paints and solvents without any masks, let alone a properly fitted one.
