That’s the name of a very interesting article that someone just sent me. It outlines the results of a Stanford study that followed a group of runners over a 20+ year period, and then compares their health histories with a similar group of non-runners.
At the time the study was started back in the 1980s, it was commonly thought that these “crazy” runners would be wearing out their knees, bringing on osteoarthritis, and that they would all be candidates for early joint replacement procedures.
But time has shown the exact opposite to be true. The onset of disabilities came 12-16 years later for the running group. Longevity was also greatly enhanced. You can see the full article here: Run for Your Lives
