Inhalt: Covering all the characteristic behaviours of adolescents — from peer pressure and risk-taking, to sex, love, bullying, friendship and more — adolescent psychologist Lucy Foulkes shows that time and again we mistake, dismiss and even try to prevent what is actually normal and healthy. Among many surprising insights, she explains why self-consciousness, anxiety and sensation-seeking are crucial features of this developmental phase. She shows that teenagers are socially conservative as much as rebellious, and that apparent recklessness is usually calculated. She reveals why being popular can be just as hard as being lonely, and why friendships at this age shape us for life. Adolescence is often difficult, sometimes extremely so, and most of us have yet to come to terms with our own. And yet Foulkes shows that adolescents have an extraordinary capacity for resilience, empathy and mutual support, and that even the most challenging experiences are part of an essential process of self-discovery. This is why understanding adolescence is the key to understanding ourselves.
