My old man was/is a plumber, he's 70+ now and back in the day they did everything, usually had lead in his lungs every day, along with the asbestos which he still has with him. I asked him what I should do when I leave school, I just thought I'd be a plumber like him, but he told me to be an electrician because all they did was change light bulbs all day. After 20 odd years of rewiring houses with hammers and chisels then using chasing machines my wrists, elbows and shoulders are buggerred and me knees, and me
