I have been exercising aerobically, including miles and miles of jogging and bicycling, since I was a teenager, and I have controlled my blood pressure through a low-fat, low-sodium diet since my early 30s. My resting pulse rate is in the mid-40s, and it still recovers rapidly following exertion. My father is overweight and type-II diabetic, but his heart is still ticking after 78 years, and his brother is still going strong at 80. I see no reason whatsoever, for someone in my particular circumstances, to undergo a cardiovascular stress test.
