Thank you Dr. Bob, You told me more than my doctor friend did. I hope you were not thinking that I was in any way advocating leaches. Your info about maggots triggered a vague memory re: leaches and there use to reduce fever. My friend used the example to explain somthing to me about the immune system & fever. You commented on magnets, but I won't weigh in on that. I have too much respect for you, and I think Marjorie is one of the most helpful, compassionate & intelligent of my new cyber friends. Someday I'd like to ask you about Radio waves used for medical purposes. I am always interested in a Doctors perspective. I know someone that works at the University of Washington Medical School that is doing research. He thinks that it is the greatest thing since sliced bread. He has also said that most of the "old school" docs think it is a joke. David Meigs aka: Pappy [log in to unmask]
