They are so compelling. As humans, we have a natural tendency to see faces in even the abstract, like the man in the moon or Jesus on toast. Even from birth, we are drawn to faces. Infants will look at faces longer than they will look at anything else. Faces can tell stories without uttering a word. This quote attributed to Saint Jerome says it well, The face is the mirror of the mind, and eyes without speaking confess the secrets of the heart.
