This book introduces body language from the point of view of business executives. The authors specialize in the use of body language for business and politics. I found the illustrations and photos that accompany the text to be very funny and appropriate. This is not a very scholarly book, so if you're looking for a very serious and academic book about the study of body language, then this isn't the volume you're looking for, but if you'd just like an introduction to body language from a practical point of view, then this is a perfect book to read. In addition, it is very easy and entertaining to read, so I can recommend this to anyone.
