Query: Everything that it promised.

I bought my mom & myself a copy of this book and both of us keep it handy for ready reference. I've bought a lot of health books and this is the best that I've ever read. I'm very glad to have it, have told many friends about the book and the website, and expect to read and reread both the website and the book many, many times.
