20. JIM FIXX – RAN HIMSELF TO DEATH
After Jim Fixx wrote “The Complete Book of Running” in 1977, he started a craze that still hasn’t faded away. While he didn’t invent running itself, Fixx is credited with starting the fitness revolution in America, and he’s known for making recreational running popular. He often extolled the virtues of jogging regularly, and always led by example. Fixx famously enjoyed a daily run to stay in shape, only it didn’t work out so well. At the age of 52, in the year 1984, Fixx died of a heart attack right after his daily run in Hardwick, Vermont. So maybe he ended up changing his mind on the whole running thing, after all.
