This is a frustrating book to write a review about. This subject really needs a book like this; professionally published, nicely formatted, attractively done, well advertised - something that the general public can latch onto and absorb. The information is important and advanced in a simple and easy to read fashion.... But who edited this book? It either appears to have been written rapidly with little concern for sentence structure or perhaps Dr. Gilbere is originally a foreign speaker? This is one of the poorest written book I have come across. Alot of work went into producing, formatting, and advertising this book. Maybe next time they will put some into editing. Not really a big problem given that theres alot of good info and this is a subject crying out for alternative points of view.
