Teenagers are people between the ages of 13 and 19 who experience significant physical and psychological changes as they transition from puberty to adulthood. During this stage, teenagers are more vulnerable to risky behaviors like smoking, drugs, and unprotected sex as they seek independence, but it is also a time of cognitive development, socialization, and defining one's personality. The memories of teenage years often last a long time.
