In an article I read today I was thrilled to see that science is proving wrong the warning that somehow knees will become injured because of over use and wear and tear. Knees isn fact through the studies cited were giving the opposite, that it will make ones knees stronger and keep them limber.
Personally since losing weight I have had no problems with my knees, only injury to my hips, buttocks and ITB. All not permanent. I have had less foot pain as well, since I carry less weight around for my feet to carry.
Does this ring true to you runners out there?
