As Biciclista noted, it is getting harder and harder to maintain friendships with those who "can't." If I share a common interest with them, anything it's easier, but I am losing tolerance for people who are my age (mid fifties) and have given up. I have the gift of genetics for longevity from both sides of my family. My dad is 85 and still works part time, but he has some "stuff" that could have been mitigated by exercising and good diet.As soon as my mom died, all he did was eat out, and bad food, too. She was the exerciser and healthy cook. A great role model. But no amount of exercising stopped her from getting a weird liver disease and having a transplant that didn't work when she was only 67.
So, onward!
