My mother gave me NO limitations, and truly believed that i could do anything. This included: walking, when i had rhuematoid arthritis as a child, learning music as an adult, fixing just about anything, etc, etc,etc. Howsomever reading the inital post, seems that no one has answered the original query: whattaya think of the doc? I think he came up with a clever solution, that benefited all parties concerned. Up until about 15 years ago, we had a doc who would do trades of that nature. And we still have a chiropractor that does stuff like that. There ARE still some healers, who are into healing over $$$$
