When Justin Tong was a child, other kids felt sorry for him. His parents always had him doing lots of housework such as carrying out the rubbish and sending newspapers. But when he grew up, he was better off than his childhood friends and lived a happier and healthier life.

This is the finding of a 40-year study that followed the lives of 456 children in London. It showed that the children who had worked hard in childhood had a richer and a happier future. "Children who worked in the home or community gained competence（能力） and came to feel they were worthwhile members of society," said Daniel Brown, the psychologist（心理学家）who made the discovery. "And because they felt good about themselves, others felt good about them."

Brown's study followed these children in great detail. Interviews were repeated at ages 25, 31 and 47. Under Brown, the researchers compared the children's mental-health scores with their childhood-activity scores. Points were awarded for part-time jobs, housework, effort in school, and ability to deal with problems.

Working at any age is important. Childhood activities help a child develop responsibility, independence, confidence and competence — the underpinnings （基础） of emotional health. They also help him understand that people must cooperate and work toward common goals. The most competent adults are those who know how to do this.
