Hi: My wife and I sleep on a magnetic bed, use a magnetic pillows, walk on shoe inserts that are magnetic and benefit from the use of magnets in other areas. There are a number of reference books on the use of magnets and the following two might give you a beginning. "The Body Electric" by Robert O. Becker, MD and "Magnet Therapy" by Holger Hannermann. The application of magnets goes back to the early Chinese and Egyptians. Happy reading, Bob
