When I turned 50, I was morbidly obese and had a long list of physical complaints. I was chronically exhausted and could no longer do or enjoy what I wanted to do. I was ready to turn it around. Through diet and exercise, I reversed the curse and now, just shy of my 53rd birthday, I can do anything I want to. I am off all medications and only need to see my doctor for an annual checkup.

My sports are now my workouts. Far from drudgery, my training workouts are fun and I look forward to them. They are the reward for all the work I've done. I feel great and have tons of energy. My favorite activity is mountain biking and I compete in sprint and Olympic triathlons, offroad triathlons, running races, duathlons and trail runs.

At my worst I felt 72, now I feel better than I did at 22 and I was active and slender at that age. You can reverse the curse of aging and poor health, I'm convinced of that.
