Still sailing at 74, but no HA yet. Maybe someday, but until then will continue as long as physically able.
Started running in 1976. anticipating deteriorating health issues down the road due to life style; sedentary, weight gain, poor eating habits, business travel, high corporate job stress, etc. Been running cross country ever since, every other day without fail regardless of weather clocking seven miles every run with many hills until last year. Age has slowed me down and now I do five miles every run. I suppose before long another reduction will be in order. Still do upper body work after every run, again without fail.
My main motivation was observing fellow workers kicking the bucket before they were 40, or a serious health setback such as a stroke, heart attack, or worse, thus leaving the family without a breadwinner. That mid life crisis set me on a new path to better health, FWIW.
