This book is a real disappointment. The title itself promises that the reader will gain new understanding of how one's subconsious rules behavior and how to rewrite the programing. It gives a very detailed description of how cells work and how they react to enviornment which early on holds out the bright promise of understanding how to change those reactions. However, the end of the book was a cheep sell out to refer the reader to the workshops presented by the writer and his partner, to the tune of $400 each. (it seems you really need two or three of them to rewrite your programing according to the web site to which the book refers the reader). As far as I can tell from the web site, it is just more worthless new age hype. Sorry I spent my money on this book.
