I hope that this article motivates you to run for the rest of your life.
The article claims that distance running may actually be better for the joints than many other sports and not running at all. For example, running may benefit your knees and help you overcome knee pain.
You may want to pass it on to the non-runners in your life, who may be concerned that running is detrimental to your health.
