Agreed. Another great thing about physical labor (to me at least) is that you can avoid most of the forced social interactions, politicking, and drama that happens in offices.

Go in to work, put in my headphones, do repetitive task, go home. It's simple, keeps me in shape, and doesn't make me loathe myself or my hobbies. If I were skilled and smart enough to get jobs that were more interesting/less evil than setting up corporate infrastructure, administering Windows, or churning out spyware, maybe I would have a different perspective, but I'm not.
