A teenager is a young person typically between the ages of 13 and 19. This stage of life is marked by significant physical, emotional, and social changes. Teenagers often explore their identities, develop friendships, and start to gain independence from their families. They may also face challenges like peer pressure and academic stress as they prepare for adulthood. During these years, teenagers often engage in various activities, such as sports, music, and social events. They may also use technology, like smartphones and social media, to connect with friends and express themselves. This period is crucial for personal growth and discovering interests that can shape their future.
