Here's a stat that will blow every neuron in your mind: The human body is capable of making more than 700,000 unique movements and more than 10,000 separate facial configurations (our face and hands being the most expressive parts of our bodies). But the really interesting thing is that all humans make at least a few of the same faces when expressing basic emotions - namely happiness, sadness, surprise, fear, anger, and disgust. These expressions were discovered in the '60s before TV made it to some distant Pacific islands and were the same on that otherwise isolated island as in populated countries. These expressions are virtually identical in every culture on earth, and we actually don't have the ability to control these basic expressions. But we do have the intrinsic ability to pick out fakes and imposters. Take the smile. A genuine smile - where the corners of your mouth turn up and the skin around your eyes crinkles - can only be produced as an involuntary response to genuine emotion. A non-genuine smile happens when the lips part and the corners of the mouth are stretched to the side.
