“A blur of blinks, taps, jiggles, pivots and shifts… the body language of a man wishing urgently to be elsewhere.” – Edward R. Murrow
This, from a man who was originally uncomfortable with the idea of television because he thought it placed too much emphasis on pictures - read: body language - rather than ideas. He went on, though, to become a pioneer in television news reporting, and appeared to settle in quite comfortably in front of the camera.
Murrow understood the power of the body language and the role non-verbal communications play in the overall message. In fact, he seemingly understood this long before the infamous study by Dr. Albert Mehrabian came long. More on that in a minute.
