Adolescence

From Srafopedia

Adolescence is a transitional stage of human development that occurs between childhood and adulthood. Adolescent humans go through puberty, the process of sexual maturation. Teenagers (ages 13-19) are usually adolescent, though in some individuals, puberty may extend a few years beyond the teenage years, and in some individuals, puberty begins in the pre-teen years.
