for adults/adolescents, you should call/activate

For adults and adolescents, the correct term to use when referring to them collectively is usually "adults and adolescents" since both terms come from the Latin root meaning "to grow up," with "adolescent" referring to those in the process of growing up and "adult" meaning fully grown or grown-up. The terms are distinct but related, and often are used together to specify the age groups in contexts like medical or emergency protocols. In addition, the term "young adults" may sometimes be used to refer to persons transitioning out of adolescence into adulthood, typically covering ages roughly 18 to 34, but "adult and adolescent" explicitly covers the full range of both groups. Thus, you should call them simply "adults and adolescents" or "adult and adolescent" depending on context, especially in formal or educational usage. The terms are well-recognized and appropriate for distinguishing these age groups.
