Take a journey deep inside the intriguing world of non-verbal communication. As human beings, our bodies communicate our inner emotions and feelings in ways that can often be easily seen by others, but at other times, are barely visible. On every continent and in every ethnicity, expressions of emotions such as happiness, surprise, anger and fear are universally recognized. These expressions are hard-wired into our facial muscles for reasons that have everything to do with human evolution and survival of the species. To the trained observer, the way people move can be more revealing than the things people say.
