An "addesent" appears to be a misspelling or misinterpretation of the term "adolescent," which refers to a young person typically between the ages of 10 and 19. This period is characterized by significant physical, emotional, and social development as individuals transition from childhood to adulthood. Adolescents often experience changes in identity, relationships, and independence during this time. If "addesent" was intended to mean something else, please provide more context.
