This document discusses concepts of age and identity. It notes that age is a social construct, as people may dress and act younger than their biological age. Cultures value age differently, with some respecting the elderly. Youth is defined as ages 12-25 and associated with rebellion and popular culture. Middle age has no set definition but most see it as 40-55. Old age is also socially constructed, though 85+ is the fastest growing group in the UK. Stereotypes of old age include loneliness and dependence, but some see it as a time for reflection. The document ends with an interactive game to determine if images shown are young, middle aged, or old.
