physiognomy \fiz-ee-OG-nuh-mee; -ON-uh-mee\, noun:1. The art of discovering temperament and other characteristic qualities of the mind from the outward appearance, especially by the features of the face.
I do this all of the time but I have never thought to stop and think about it. So today me and a friend spent a little time wondering what kind of faces convey what kind of temperament. Like a round face, or big ears, or a mole on the nose. What does a square face or a tan face convey? Try looking at people and guessing their temperament by their face, it is a good game. I declare October 11 physiognomy day.
