A hobby is good therapy. As with most other things in life, moderation is the key. This hobby will keep you company for the rest of your life if you so desire. As you stated, there's something for everyone. When I hear people say they are bored, or watch TV for hours on end, or yada yada yada, I think to myself how so little time there actually is to get all of the things done I'd like to do. I'ts fun to try different things, test, modify and observe etc. I've been in since 1976, how about you?
