I'm 68 years old now, but I've been quilting for at least 20 years (can't remember when I started, since I've been sewing all me life--started when I was 13-14) anyway, That means I started when I was about 48. We all get old sometimes, if we are lucky, and a couple of months ago my DH and I went on a cruise and I swam with the dolphins. It was wonderful and probably something your friend thinks is only for young people. Doing "young" things is what keeps people young.
