I am 65 and just began road cycling three days a week during the past year and absolutely love it. In general, I've read that intensive exercise is not good for your heart once you're age 55 or so and above. Much more moderate exercise, such as hiking or sports such as pickleball, seems to be the best form of exercise for your heart.
Your statement is so silly - it really needs no rebuttal. FWIW - each individual determines their own exercise intensity. Pickle ball or Cycling do not control exercise intensity - the person using the sport to recreate does.
Actually, cycling on a multi-speed bicycle is probably the most "perfect" form of safe-aerobic-exertion, other than a bike trainer.
Sir - your post lacks any merit -and your bias against cycling is unappreciated.
