These jobs are usually slow torture for humans to do. Do them long enough, and your body will break under the sun or you will look like a prune, get back pain or a hump and possibly skin cancer.
Let the robots do them as soon as possible.
And sitting in an office chair in front of a computer all day doesn't bring its own health problems? Weight gain due to limited daily movement, forward posture due to sitting and looking forward all day, RSI due to typing and mouse movement.
Sitting in an office chair you can do despite numerous problems. But crawling through attics, lifting heavy items - once your injured that's it, you won't be doing anymore, potentially permanently.
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.
Well unfortunately it doesn't get better than that, except when working as remote you can lie on a sofa or bed. After a full day you still have full energy to do optimal amount of physical exercise, just enough (which is relatively little) to stay in optimal condition without destroying your body.
