Face, The

Walk down a crowded street and imagine a world without faces. What would you know about the people around you? Their age? Their sex? Origins? Moods? Intentions? None of it. The reality is, the face is our most vital tool of communication... at times, a very means of survival. In a glance, a face can convey so much, so compellingly, science is only now beginning to understand its complexity. And television is the best medium to explain the visual wonder of the human face - and the science behind it.
