This is a masterful work on nonverbal body language by an exceptional observer. Joe Navarro's work has been field-tested in the crucible of law enforcement at the highest levels within the FBI. It's estimated that as much as 80% of our interaction with others is through non-verbal communication, or body language. And the vast majority of the nonverbal cues we display are driven by our subconscious mind - they are important indications of how we are feeling and what we're thinking. Joe Navarro has been studying non-verbal behavior for the past 30 years. Today Joe is an internationally recognized expert, author, and gifted lecturer, in the interpretation of non-verbal behavior.
