content: When I was sentenced, years ago, to two weeks bed rest for sciatica lower back pain, a neighbor lent me the book. I read the humorous real life story of tribulations with surgery, chiropractic, and accupuncture, then started doing the simple exercises in the book's appendix. What a great thing! Slow steady progress until I got back to enjoying tennis at full enthusiasm. I even use one or two of the exercises on a plane for ironing out the kinks from flying for a couple of hours. It has been wonderful for me!
