I discovered 20 years ago about the medical effects of rebound. I was diagnosed with lymphatic cancer,(hodgkins desease). My doctor informed me that I must have radiation and chemo. treatments after xrays. I refused the first step that I knew would lead me down the road to my doom. I stopped eating and went on a veggie and fruit juice fast for two months. All the swelling of my lympth nodes went down, but the soreness remained. My guarding angel led me to a German Homeopathic Doctor who, with one treatment, knocked it out. The cost was $42.00. I was not cured because there is no such word as "cure." Once the symptoms appear, it's already too late, I became symptom free. I changed my eating habits and got a small trampoline, and have not only remained symptom free since, but healthier at 72 than I was at twenty. I need no other exercise. Rebounding is the only exercise that keeps my lymphatics working as it should. This book is the best of it's kind and will in time, prove to be the "Bible of new age medicine!"
