Gym membership

My Dad gets free gym membership with his insurance and he is actually going to the gym. I am in total shock. This is the man who laughs because people drive to the gym to workout. He doesn't use the machines, but there is a "Silver Slippers" excercise class that he likes to go to. As it sounds, it is excercises for seniors. I think it is a great thing for him to do. Maybe if I work real hard, I can work up to a silver slipper workout myself.
