Overall: This book was exactly what I was looking for. It does not go into every type of common body gesture, but definitely enough to keep you busy for a while. Immediately after I started reading this book I began to notice the behaviors in myself and my colleagues. I think this book is more useful for reading people in social or personal situations because it is much easier to accurately read someone's body language in a purer/ more natural state. For example, in a business meeting a colleague may rub their chin. The book would say that can indicate someone who is thinking/contemplating and secondary gestures should be watched to indicate what their decision may be. In a business meeting that same gesture could be a cover up for day dreaming, an attempt to please their boss or simply trying to stay awake. When I make assumptions based on the book in business settings I have been wrong because so many factors could lead to the emotion that is creating the language and most of which have nothing to do with me or the current interaction. In personal settings it is spot on and can sometimes be very entertaining. The chapter talking about women and what their facial expressions indicate is priceless and men should read it just so they know when to chance course in their behavior or conversation.On a social front I tested out some of the attractive and open female gestures in courting or even talking with men and they certainly do work. For example showing the inner wrist is supposed to be a sign of openness and femininity and when I casually had that part facing I was treated much differently.Layout: The material is interesting, but the illustrations and simple descriptions make the lessons learned in this book easy to remember. They also make connections to the animal kingdom or how the gesture evolved from a functional action when possible which helps me remember and feel more engaged with the material. The author also has a sense of humor and provides the right about of space and breaks in the text with humor, pictures and examples to keep it from getting too dry. This layout also follows the tell you, tell you again and tell you what they told you approach so you can even read it in public and watch for the behaviors while you are reading.There is not a whole lot I would change about this book except the claims are much greater than anyone can possibly make. Sure it can help you read someone's true feelings, attract people more easily and tell when someone is lying, but it is not a surefire method and cannot make you successful in all types of interpersonal situations on its own. This is just a tool and should be clearly described as such.
