introduction - I agree-
some jobs demand a intence physical effort and a intence mental effort
1. reason 1:
some people work in hard eviroments THAT affect their Physical and mental
Health because some jobs demand a intence physical effort every work day
for example construction, mining, or factory work. theses jobs can wear
down the body through time and affect their health also these workes work
in dangerous places where they can die at any moment. so these workers
should be retired early.
2. reason 2:
some people work in jobs THAT are very demanding with high stress
