The Definitive Book of Body Languagesocial scientist - the Body Language Watcher. Just as the bird-
watcher loves watching birds and their behaviour, so the Body
Language Watcher delights in watching the non-verbal cues
and signals of human beings. He watches them at social func-
tions, at beaches, on television, at the office or anywhere that
people interact. He's a student of behaviour who wants to
learn about the actions of his fellow humans so that he may
ultimately learn more about himself and how he can improve
his relationships with others.
