Adolescence
Adolescence refers to the development stage starting after puberty (also known as pre-adolescence) and ending around the age of 21. Puberty begins at about the age of 11 and some authors include it in adolescence. Others regard adolescence as such starting at age 13 or 14. Adolescence is characterized by a set of physical, hormonal and psychological transformations in the person.
