Understanding happiness depends on age, for young this "excitement" for people in the age of "contentment". Scientists from the University of Pennsylvania conducted a study in five different age groups - adolescents, people aged 20 years, from 30, 40And 50 on the subject of awareness and happiness.
Professor Cassie Mogilner says:
The difference probably lies in the priorities for the future and the present. Young people focused on the future and those who appreciate the present. Among all participants a survey was conducted, it was found that more than 60 percent of youth bind understanding of eternal happiness with emotional growth, excitement seeking, and more than 80 elderly people tend to see happiness in the satisfaction with life. Moreover, the definition of happiness varies in direct proportion to the age of life.
