I checked the Savage Garden and you are correct on what it says. *The book is a great book and Peter sure does know alot. *And no offense to Peter but the book is not 100% absolutely correct on everything in it. *There are other books and other equally knowledgeable people. *It is always best to formulate your knowledge from more than one source when possible. And equally important to realize that if your knowledge is coming from a single source that there is the possibility it may be flawed.
