Everybody knows someone who can walk into a room full of people and, within minutes, give an accurate description about the relationships and feelings those people are experiencing. This ability to read a person's attitudes and thoughts by their behaviour was the original communication system used by humans before spoken language evolved.

The Definitive Book of Body Language is by no means the last word on body language, nor does it contain any of the magic formulae promised by some books. Its purpose is to make you more aware of your own non-verbal cues and signals and to demonstrate how people communicate with each other using them.

This book isolates and examines each component of body language and gesture, though few gestures are made in isolation from others; and at the same time it tries to avoid oversimplifying. Non-verbal communication is a complex process involving people, words, tone of voice and body movements.

The book gives you greater insight into communication with your fellow humans, so that you can have a deeper understanding of other people and, therefore, of yourself.

The original book was intended as a working manual for sales people, managers, negotiators and executives and has sold 5 million copies worldwide. The Definitive Book of Body Language is the result of over 30 years of involvement in this field and has been expanded in such a way that any person, regardless of his or her vocation or position in life, can use it to obtain a better understanding of life's most complex event - a face-to-face encounter with another person.
