Thanks for that reference John, will get right to it.
Here is an interesting story for you; I did have my right knee replaced in April, and have been doing PT to re-strengthen the leg since then. What has happened to that leg, below the knee, is that it has redeveloped hair, just like I had when I was much younger (now 83). But the other leg is almost completely bare of hair as was the right one before the surgery. Have showed this to several health professionals, and they do not have an answer, and they tell me they have never seen this before in legs operated on. Only possible answer they say is it is due to increased blood flow from the exercise. Sadly, I still have the neuropathy in the right foot even with the possible increased flow. So not sure. But again, thanks for the reference. Will check it out.
