Ancient Aboriginals have a rich culture centered around family, nature and tradition.
In Tasmania, Aboriginal warriors would often paint their faces.
A painted line on the forehead represents the self. Lines on each cheek represent the knowledge one attains in life. The portion where the cheeks meet the nose is intentionally left blank.
The blank area represents the knowledge one has yet to attain in this life.
A researcher and Psychologist from the National Institute of Aging noted that personality traits change little after the age of 30. In short, people are set in their ways, and change of any kind is limited.
