Earlier quoted context omitted.
I used to think it was great, but now I think about a powermatic bandsaw. (AvE was involved. I chose wood shop because he said there weren't any old welders i.e. they don't live long)
That's a funny claim. I know welders of all ages. The older ones seem to tend to migrate to other work which requires less physical exertion, but that's true of every job I see. I don't know any old dancers, but that doesn't mean dancing is lethal. It means they tend to shift to choreography or teaching or something else as they get older.
His tone of voice was really funny. ISTR it was on a video about beginning stick welding. http://www.youtube.com/watch?v=2fUAHkUfTps&t=17m34s
