Without the information in this book, I would have been taking antibiotics for 15 years to alleviate major skin and scalp conditions. This was the answer to my problem from both general practitioners and medical specialists! Never once was I tested for stomach acid levels - in Aging Without Growing Old, I came across my exact symptoms, headed off to a health food store and purchased a digestive product with hydrochloric acid and two weeks later - positive results. Still taking the digestive tablets. That was 10 years ago - I am often complimented on my great skin condition. I have taken on board much more advice from this fantastic book and am really AGING WITHOUT GROWING OLD!! I have just purchased two more copies of the book to give to friends. GREAT BOOK, GREAT ADVICE. RECOMMENDED HIGHLY. TAKE RESPONSIBILITY FOR YOUR HEALTH - YOU'LL BE GLAD YOU DID.
