Hippies were members of a youth movement of the 1960's and 1970's that started in the United States and spread to Canada, the United Kingdom, and many other countries. The hippies rejected the customs, traditions, and life styles of society and tried to develop those of their own. Most hippies came from white middle-class families and ranged in age from 15 to 25 years old. They thought too many adults cared about making money and little else. The term hippie may come from the word hip, which means "tuned-in" or aware.
