An adolescent is a young person typically between the ages of 10 and 19, undergoing significant physical, emotional, and social changes. This stage of development is marked by the transition from childhood to adulthood, where individuals experience growth spurts, hormonal changes, and the development of secondary sexual characteristics. During adolescence, individuals often seek independence and form their own identities. They may face challenges such as peer pressure, academic stress, and the exploration of relationships. This period is crucial for developing skills and values that will shape their future as adults, influencing their interactions with family, friends, and society.
