well, then there's comparing ourselves and our bike friends to the other friends and relatives. the cyclists with trim bodies and younger faces; or the ones with serious health problems exacerbated by lack of exercise, weight gain, diabetes, hip and knee replacements, the inability to walk a distance; people we used to go hiking with now don't even want to mall-walk with us anymore because of knees/backs/hips etc.
My newly departed stepfather was a textbook case in what NOT to do. he had a reasonably healthy body but when he retired, he decided that he was done working. He got more feeble every day. When it was time for the BIG fight, he had no reserves at all. He taught us a lot by his mistakes.
I am very sad to lose the closer friendships with the friends and relatives who used to be our age but now are suffering from all those old people problems. But what can I do? I can only continue to take care of my body and hope that they get some inspiration from me and maybe won't get too many resentments.
Cycling without a doubt has bought ME some time.
