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. Body Language Decoded features interviews with some of the world’s leading experts in human communication.

Why do we sleep? And what does sleep have to do with memory, trauma, and our emotions? From fruit flies to whales, virtually every animal sleeps. But why? Why do we need to spend nearly a third of our lives in such a defenseless state? Scientists are peering more deeply into the sleeping brain than ever before, discovering just how powerful sleep can be, playing a role in everything from memory retention and emotional regulation to removing waste from our brains. So why are we getting so little of it?
