Yeap. I also think there is something about physical work that is more fulfilling in some way. I had a college summer job for 2 summers working as a car tech (simple stuff like oil changes, brake jobs, etc). In the years after college I was often very nostalgic about that job....

There is a surprising lack of mental stress that comes with such jobs (you're not 'taking work home with you'). You arrive and the car needs a brake job, you leave work and the brake job is done. There is a tangible feeling of accomplishment at the end of your shift....unlike modern office work where projects just seem to drag on and on and you only make incremental, somewhat ephemeral daily progress.
