Do you strictly only do metal working? (poll)

I've wondered for a while, there are lots of things that attract people to machining, and with that come areas. My previous instructor would say (in no offense) but in this class we are not doing wood working, we are doing precision machining ". he also dabbled in leather working in his free time. So it raises the question "do people that do machining mostly do purely metal working or other tasks including wood or leather just as much?"
