I am surprised that there have not been comments from list members on the segment about the so-called "SHAM SURGERY". Personally I thought that headline was over sensationalizing on the part of the network. They will do anything to attract viewers. But as far as the content of the program, I thought it was probably good information to put out. I have no opinion as to whether that type of medical research should be done, That is a tough question for more learned people than I to debate. One more comment. Don't they have a more high-tech way of drilling than to use a 100 year old invention, a brace and bit? Lanier Maddux 63/2 Chattanooga Tn.
