Hello All,

Excerpts:
"One possibility is that walking around on hard, paved surfaces all the time isn’t good for our knees. In support of that possibility, they cite a 1982 paper in which sheep spent 2.5 years living either on concrete and tarmac or on wood chips and pastures. The sheep in the concrete jungle had noticeable changes in the cartilage and bone of their knee joints, and maybe we do too.
Another possibility is shoes—and they’re not talking about trainers. They cite a 1998 study showing that high-heeled shoes generate abnormally high forces on the knee joint, and note that, in their analysis, women were about 50 percent more likely to have knee osteoarthritis than men.
But the biggest factor, they suspect, may be physical inactivity. Joints, like muscles, have a use-it-or-lose-it aspect. If you sit at a desk all day, you end up with thinner, lower-quality cartilage in your joints, and weakness in the muscles that would otherwise take some of the load off your joints. The problem, in other words, isn’t too much running; it’s not enough running."
