This is a summary of the original book written by Joe Navarro. It has been summarized in order for the reader to absorb substantial information in about thirty minutes reading time. People lie for different reasons; whether to get out of a difficult situation, to avoid further unnecessary explanation or in a bid to be polite. What many people don't know is; whenever they tell a lie with words from the mouth, their other body parts are revealing non-verbally what they really feel and the fact that they are being dishonest. Non-verbal communications don't deal only with lies; it tells the story of how we feel, who we like, where we don't want to be and so on. After reading this book, insight will be gained about the nonverbal "tells" our body gives away under certain circumstances and how we can correctly interpret the nonverbal "tells" that the people around us give off. This will not only improve our quality of life but also our day-to-day interaction with other people. You may not become a human lie-detector or mind speed-reader, but you'll be the closest thing to it. Regardless of verbal communication, you will be able to figure out when your spouse has had a bad day, when your kid is becoming truant, when your boss is unsatisfied with your work etc. Also, through the use of your body language, you will be able to know what non-verbal cues to give off to exhibit confidence, self-assurance, and inspire empathy.
