This book is well written and has excellent photographs to allow you to fully see the important features of the Alexander Technique. It is my absolute favorite Alexander Technique book! I have read several of Gelb's books, starting with one on Mind Mapping as I recall, and I think he is a great writer and no doubt an excellent human being. He is excellent at explaining fine details of a not so obvious subjects. If you have pain in your back, or neck,posture issues, wrist problems, and just feel awkward moving in your body or a bit out of sorts during any activity, or even have trouble with social intelligence issues, or fell you cannot get into your writing or art (like writer's block), give this book a try. It is about being a human in a human environment and body in our modern world and functioning optimally. I would think athlete's would want to read it. People with chronic voice problems may benefit (and get the books by Dr Morton Cooper for vocal issues also. Many problems in medicine are really FUNCTIONAL and can be remedied by the patient who is willing to do the reading and research. Many times doctor's simply cannot get to the root cause because it may take hours, but YOU CAN do it for yourself. So I highly recommend this book.
