This reads like it was written by a person who has never seriously trained at distance running. The vast majority of such training happens in Z1/2 and is some of the healthiest motion you can put your body through. People die doing lots of things, and many other sports besides running, usually because they had another condition or disorder. And besides, I'd much rather have a stroke and drop dead at like 70 or 75 having enjoyed an active life than deal with all the health risks and low quality of living associated with being sedentary.
