"One of my colleagues left a message on my answering machine: “Hang up your running shoes. Jim Fixx just croaked.” However, the stats indicated that people who logged more than 25 miles per week were more likely to sustain running-related injuries, so I just limited sessions to between 6 and 7 miles three times a week and was fine. All the races were very early in the morning, and there were hardly any races in July and August, but I liked swimming too, so no problem."

Exactly which part of "Cardiac Stress Test" are people ignoring?

Jim Fixx's autopsy showed a congenital heart problem. He also had heart problems that apparently dated to his days of heavy smoking and heavy weight before he took up running. His autopsy 'revealed that atherosclerosis had blocked one coronary artery 95%, a second 85%, and a third 70%.'

Fixx was a cardiac time bomb, whether he ran or not.
