Query: Please read it!

Everyone should read this book. As a matter of fact, after I read the book, at my doctor's advice, my husband has read it, and I have given books to three sisters, my best friend, and a physician for whom I work. I still have 3 more copies available to give away. If you are trying to maintain a healthy lifestyle, please read it. It has so much information, written in plain English, that everyone can get something out of it.
