I bought this book for my husband. He loves this book. He keeps going back and reading parts of it over and over. I don't know how many times he has come into the room where I am to read a section to me. He was so impressed with this book, he had me order eight more books for family and friends. I would say if he thinks of someone else who could use one, we will probably order even more of them. My husband feels after about two weeks he already has improved his health with the information he has aquired in this book.
