That's a good idea. I have a male cousin who has taken early retirement from being something mysterious high up in the civil service. He is in his mid 50s, his wife still works and he has taken over all the cooking, because that is what his wife hates doing most. The only problem is, he likes to bake and make sweets, and she is on a permanent diet as a result. Things are getting quite heated. She told him to make something less fattening for that night's meal, and he still made a pie - but with vegetables in it!
He has just started a course with the OU on military history, that's not the exact name of the course, it was something that sounded quite intriguing, and seems to be thoroughly enjoying it. However, I do think that he, like you, needs to get out more and make more male friends. Men seem to make work friends rather than life friends, don't they. I know DBH does, he rarely bothers to seek out a person in real life, although he is very happy to communicate on facebook. Once he leaves a school the friends he has made there seem forgotten. I am the one who stays friends with them - and I didn't even work there!
