The life of a teenager is hard. Here and learning problems, and new contacts with their peers, the first attempts to build a relationship with the opposite sex, says The Daily Mail. Not every adult will sustain such a stream of emotions. The scientists interviewed 474 teenagers from affluent families. The obtained results were compared with a group of juvenile delinquents.
Volunteers were asked to keep a diary and track your mood changes. It turned out that with age, the mood swings became less frequent, and the psyche has acquired the characteristics of stability. Apparently, by 17-18 years young people learn to cope with emotional extremes.
