Does your chin shape say something about your personality? The 'face reading' people think so. There is a whole 'science' of face-reading called physiognomy or personology.

The chin shape is said to be one indicator of personality. People who have an angular, wedge-shaped chin are thought to have more stubborn or argumentative temperaments. Many military people and trial lawyers have such chins. People with more rounded chins have a more co-operative attitude.
