Photography and hiking are good options.
Edit: Going to the sauna in the men's change room at the local gym is also a good excuse.
[/QUOTE. As an 80 year old, I have many limitations, can't play tennis or go curling, (rotator cuff issues). Luckily, I can and do play golf 1-2 times a week, but can't walk a course, (osteo arthritis, lower back). Problem with golf even if you are a member of a private club, it is very difficult to get tee times and public golfers have a horrible time. I hate going for walks just for the sake of walking, must have a purpose and bigger problem is ALL my male friends used to go to pubs on a daily basis,but I can't find them anymore. My one saviour while at home in my condo is playing online poker 4 - 6 hours a day and actually making $. Lastly, can't visit my son and his family in Europe. Thank GOD for good wine. LOL.
