Hello @billi123 and @steem-health,

how death by exercise

Guy goes out for a run. It's just a 4-miler--nothing, really, to a seasoned marathoner who usually runs 10 miles a day, 7 days a week. Nobody knows why he stops 40 or 50 yards short of his front door--maybe he's checking his pulse, maybe he's tying a shoe--but everybody knows what happens next to Jim Fixx, the 52-year-old patron saint of running: He dies.

You've heard that story. But you may not know about Edmund Burke, Ph.D., who was to serious endurance cycling what Fixx was to running. He died on a training ride last fall, at age 53.
