EXCERPT:

Over the last century, advances in technology
have massively expanded our choice of
ways to connect to each other. Nevertheless
our original means of communicating –
talking face to face – persists as the most
immediate, natural, and universal means we
have of communicating. Conversing face
to face, we have at our disposal not only the
full richness of our spoken language, but
also a nonverbal vocabulary that includes
gestures, shifts of gaze, and facial expressions.
When we need to convey our innermost
feelings, explore a sensitive topic, influence
a key decision, or simply make others
laugh, this is usually the channel we
prefer.
