Describe three stages of adolescence

Early Adolescence
Early adolescence is the first stage and occurs from ages 10 to 14. Puberty usually begins during this stage. Like Henry, people in this stage become aware of their rapidly changing bodies and start to worry about their physical appearance. They might experience shyness, blushing, modesty, and a greater interest in privacy.

Middle Adolescence
Middle adolescence is the second stage and occurs from ages 15 to 17. By this time, puberty has passed. Teens in this stage are extremely concerned with how they look, and they think others are concerned, too. They spend a large amount of time grooming, exercising, and modifying their physical appearance.

Late Adolescents (18-21.... and beyond!)
Late adolescents generally have completed physical development and grown to their full adult height. They usually have more impulse control by now and may be better able to gauge risks and rewards accurately.
