‘Teenage-hood’ has acquired the status of a universally applicable category of human development, with the experience of ‘teenage-hood’ contingent on one's circumstances and adoption of certain values.

In this liminal space between childhood and adulthood, teenage-hood is encouraged to be and characterised as a time of self-discovery, anxiety, experimentation, instability and vulnerability.
