The subtitle of the books is "secrets to look, feel, and think younger everyday." Don't take that too seriously as far as the outward cosmetics of your appearance. The thrust of the first half of the book is combating Alzheimer's disease. That is not a bad thing, mind you, but the title might be misleading to some readers. The second half deals to a small degree with appearance and mental states, such as depression. Amen has written something of a cheerleader's book: "Eat the rainbow! Yay! Life-long learning! Yay! Exercise! Yay! Defeat Alzheimer's!" There is little that a reader who had kept up with current research in popular magazines will find new, though the reading might inspire action rather than passive understanding. I enjoyed it because the topic is of particular interest to me, and the information was very practical. However, I find fault in two ways. First, Amen doesn't hesitate to frequently mention his own paid online services, his clinics, supplements, and his wife's cookbooks. At times, the book sounds like little more than an infomercial. Once is enough for the fans, doc. After that you sound like a money-grubbing nag. Second, I listened to it in audio. This is a terrible book for that format. There are so many lists: organic foods to eat, non-organics to avoid, best fish, Glycemic Index ratings for food, etc. All these lists make this book nearly impossible in audio form. If you want the lists, anecdotes, and advertisements, choose the paper or electronic version so you can refer back easily.
