Dear Michael Gary Duncan and Barbara Yacos: Thanks for the encouragement on the biting the lip matter. Funny how a little thing like that becomes a big thing that has the potential for being a morale downer. Thanks for the support. I'm still interested in hearing from those of you who exercise. Is it desireable to exercise "into the pain?" I used to do that with the saying that the Nautilus people put forward, "no pain, no gain." Then I heard that it wasn't really a good idea. But for those of us with constant pain, surely we have to do that anyway. What do you think? Bob Newbrough ([log in to unmask])
