This mouth-covering gesture

This mouth-covering gesture becomes even more refined in adulthood. When the adult tells a lie, his brain instructs his hand to cover his mouth in an attempt to block the deceitful words, just as it does for the five-year-old and the teenager, but at the last moment the hand is pulled away from the face and a nose touch gesture results This gesture is nothing more than the adult’s sophisticated version of the mouth-covering gesture that was used in childhood. This is an example of the fact that, as an individual gets older, many of his gestures become sophisticated and less obvious, which is why it is often more difficult to read the gestures of a fifty year-old than those of a much younger person.
