A teenager is a person typically between the ages of 13 and 19. This stage of life is marked by significant physical, emotional, and social changes as individuals transition from childhood to adulthood. Teenagers often experience growth spurts, hormonal changes, and the development of their identities and personal values. During this period, teenagers may face various challenges, including peer pressure, academic responsibilities, and the exploration of relationships. They often seek independence while still relying on their families for support. Activities such as school, sports, and social events play a crucial role in their development and socialization.
