A little off topic, but I've always felt that physical labour is undervalued in our society. I did some work for a removalist and that was alot harder (and probably more satisfying) than my better-paid office job. My perfect job would involve some blend of physical and knowledge work, but I'm sure the economists would point out the inefficiencies of such a job.
A typical day for me is entirely in front of a computer screen, but has over the past year occasionally involved physical work actually putting together a robot. I can attest, some time away from the PC doing mechanical work can be nice.
the people that usually do physical labour, generally have lower IQ. (i know, I am heavy generalizing), so to them it is ok.
For a very smart person, just the thought of doing the same physical routine, everyday, will drive them nuts. Even the thought of it can be depressing.
Probably, for a blue collar worker, the idea of sitting all day in front of the computer, and thinking these wierd problems, will drive them nuts too.
