I recently attended a good friend's 50th birthday party. He has been quite a hobbyist over the years. We were having a few (too many) drinks and he started to talk about ending his hobbying. He basically said, "How long am I going to be doing this? I think I'm getting too old." He explained that some SP's had age limits and expressed concern that younger SP's would not want to see him. Made me wonder how old is too old for a hobbyist and how old is too old for an SP. I would be interested in the opinions of ladies and gents.
