Bicycling is more good exercise, than I ever imagined. Doing 20-40 miles a day, at age 74, keeps me in good stead, with my GP, Urologist, and Cardiac Docs..... Even my Dentist makes note, as he is also an ardent bicyclist!

Besides that, it's as much fun, as it was when I was 12!

Now, if it could just do something for my ears!!!!!!!!!!!!!!!!!!
