Title: Low, low level...
Review: This book is really a poor book ! Read in less than two hours, it may have an interest for people who have not the slightest idea about that subject... There is no science in that book ! I regret the few bucks I have paid for it...If you read French and you want a really good book on non-verbal communication, try Jacques Corraze "Les communications non-verbales" that is a top level book !
