This is the stage where adolescents’ cognitive development is increased. They are able to memorize many concepts, they become very creative, they reason logically and are very imaginative. Their social development also improves a lot especially in developing relationships with members of opposite sex. Their emotional development changes to aggressive state especially when dealing with adults like their teachers and parents. Adolescence stage is characterized by a lot of adventure on both positive and negative health behaviour and it is the stage which acts as a junction to positive or negative health behaviour. Most of the health behaviours either positive or negative which are experienced in adulthood began in adolescence.
