Age 15 is a significant stage in adolescence, typically marking the transition from early to mid-teen years. At this age, individuals often experience rapid physical, emotional, and social changes. Many teenagers begin to develop a stronger sense of identity and independence, exploring their interests and forming deeper relationships with peers. In many countries, age 15 is associated with important milestones, such as the completion of middle school and the beginning of high school. It is also a time when teenagers may start to take on more responsibilities, such as part-time jobs or volunteer work, contributing to their personal growth and development.
