If you think all manual labor is mindless work, you're a bigger @#!*% than most of us thought. I am a manual laborer but it is far from mindless. As an electrician, my mind is constantly working to remember the codes that I have to follow, the rules for the different types of construction that I do, and I have to figure out the best/easiest/cheapest way to do every job. And I have to do all of this without a computer. In fact, I would bet that my mind is just active while at work than most of the people on this board (probably more active in your case). But thanks for being a @#!*% anyway.
