Using exercise to control blood sugar on doctor's advice. Trying to avoid having to use medication. Remebered how nice it was to ride a bike while I was in Thailand 30 or so years ago, and hating running, I bought a bike.

Got hooked on it. Gave up booze. Gave up smokes. Gave up 65 pounds. Now I try to get between 10 and 20 miles in per day on average. Love it.
