I totally agree. Last year I signed up for Archeology of the Bay Area classes - we even had field trips. It was SO much fun! I learned a lot about the area I live in and want to learn more. I also met a lot of really nice people to share interests with. IMHO you're never too old to learn new things and if you think you are, then you truly are too old.

P.S. Richard, I'm also a Notary. Boring class, but it's part of my job and a little extra something I can add to my resume.
