Fifteen-year-olds are typically in the middle of their teenage years, often attending high school. At this age, they are developing their identities, interests, and social skills. Many are involved in extracurricular activities, such as sports, music, or clubs, which help them build friendships and explore their passions. Cognitively, fifteen-year-olds are capable of more complex thinking and reasoning. They begin to understand abstract concepts and can engage in discussions about various topics, including politics, science, and art. This age is also marked by increased independence, as they may start to take on part-time jobs or volunteer opportunities.
