I’m 66 and cannot imagine a life without exercise. I always exercise with rock and roll, though, the lack of which might be the key to other people’s reluctance, and may be why I don’t like yoga — an insight that just came to me. Yoga and rock and roll don’t really mesh.

People love to hate exercise, but it ceases to be mere exercise when you’re listening to your favorite music.

I wish I could run and hike and ride my bike like I used to do. I am confined to working out in the pool with an MP3 strapped to my forehead. I actually don’t do that much swimming.

After my next hip replacement in January, though, I expect great things — I expect to get back on my bicycle. Woo hoo!
