But I do not believe it is necessary, or right, or even natural.
Look at children: They use every means at their disposal to convey meaning: Voice (both words and non-words), tone of voice, facial expression, body language, and what ever gestures such as iconic or pointing, they can come up with.
To me sitting in a chair using a well modulated voice and little or no gestures is down right unnatural.
Why is it considered "civilized" to limit your communication abilities to the absolute minimum?
