While I laughed, I don't find this to be very true at all for working in metal.

Working on metal seems to have WAY fewer injuries than people who work on wood. Metal working is almost always in a vise and your hands are on levers/cranks--away from the cutting surface.

Whereas, with woodworking, your hands are almost always the motive force and directly next to the cutting envelope.

Simply take a look at the hands of long time machinists vs long time woodworkers. The woodworkers are the ones missing some finger bits.
