Query: A book everyone needs

A treasure in the trashbin. I bought this book on the bargain table and am glad I did. Filled with easily digestible chapters describing gesture clusters, illustrated with dozens of drawings to provide visual examples of the topic.In my line, I need to read people and their responses to my ideas. This book helps me to do just that. It also gives ways of taking charge in a situation by using body gestures. If you know the gestures, you can resist someone else trying to dominate you.It's worth the price. Everyone who deals with other people needs this book.
