Word of Mouth - Body Language

How important is body language in the way we communicate? Are some people much better at it than others? Can good body language be taught? Chris Ledgard investigates. Chris visits Dr Harry Witchel for some body language training, looks into some body language myths, and talks to impressionist Kate Robbins about the way she uses her face and gestures when mimicking people. Produced by Beatrice Fenton.
