Ham radio. But I'm not really too active on it, I do have a small collection of old radios. My oldest one is a National SW-3 receiver that was given to me, dates back to the 1930's. I have another one from the '40's and a couple from the '50's and 60's.
Mmmmm, how many women go to the OBGYN when there is NO problem? Some, but probably not the majority. Think about it.
Mine's woodworking. I didn't see it in your list. Right now I'm trying to collect a lot of machinery to do what I'm interested in at the moment, which is making marble runs & machines. Harder than it looks.
