With a fulltime job and you working till death, you don't have time to do much. The local eagles/lions/moose/etc club, you at least got to go out and have dinner, chat with people, make friends, etc.
I checked out the local Masons lodge, and I was at least 20 years younger so I didn't ask to be sponsored. My friend in Ireland joined the Masons, he says the lodges are filled with younger people from 20s and up.
I read the "Starting over" and think, did you change your hobbies and activities too? There's so much to do now, how can one be bored. Even a trip to the library and parks is cheap and free.
