This book was required reading for a course I took in college, and it stuck with me enough that, when I was looking for a book on the basics of body language again 10 years later, I picked it up again. This book does not hold the secrets to interpreting human behavior, but it does have some handy tools to figure out how others may perceive what you are saying and how you can attempt to modify your own gestures to convey different sentiments non-verbally. The book is largely devoted to business, particularly in pitching sales, but much of the guidance can apply to other areas of life as well.There are a few sections that are outdated - for instance, which direction a potential buyer blows their cigarette smoke is not often something we get to take into consideration during a business meeting; and I can't fathom the idea of someone EVER getting out of their car during a traffic stop to try to persuade an officer not to give you a ticket these days! But most of the information is still relevant and applicable. Definitely a good, quick primer to understanding body language.A classic on body language. Up there with Morris. Book arived on time and as described.There were a lot of things in this book that I never even thought about with body language!It is fairly informative but has lost a star because I get the distinct feeling that the author has left a few things out, either so as to create another book or to keep back for personal use. Otherwise the content is good and the illustrations are all very accurate.Great deal!Loved the book! It's loaded with detailed information and is very easy to understand. Great illustrations, too..An amazing revelational account. It contains lessons that are sure to enhance business, social as well as personal relationships. I recommended this to my sister and she agrees that it's a must read.Useful resource book.
