Over the last 70 years, researchers have been studying happy and unhappy people and finally found
out ten factors that make a difference. Our feelings of well-being at any moment are decided to a certain
degree by genes. However, of all the factors, wealth and age are the top two.
Money can buy a degree of happiness. But once you can afford to feed, clothe and house yourself,
each extra dollar makes less and less difference.
Researchers find that, on average, wealthier people are happier. But the link between money and
happiness is complex(复杂的). In the past half-century, the average income (平均收入) has sharply
increased in developed countries, yet happiness levels have remained almost the same. Once your basic
needs are met, money only seems to increase happiness if you have more than your friends, neighbors and colleagues.
"Dollars buy status (social position), and status makes people feel better," say some experts, which
helps explain why people who can seek status in other ways, scientists or actors, for example, may happily accept relatively poorly-paid jobs.
In a research, Professor Alex Michalos found that the people whose desires (欲望), not just for
money, but for friends, family, job, health, rose furthest beyond what they already had, tended to be less
happy than those who felt a smaller gap (差距). Indeed, the size of the gap predicted happiness about
five times better than income alone. "The gap measures just blow away the measures of only income."
says Michalos.
Another factor that has to do with happiness is age. Old age may not be so bad "Given all the
problems of aging, how could the elderly be more satisfied?" asks Professor Laura Carstensen. In one
survey, Carstensen interviewed 184 people between the ages of 18 and 94, and asked them to fill out an
emotion questionnaire. She found that old people reported positive emotions just as often as young people. Some scientists suggest older people may expect life to be harder and learn to live with it, or they're more
realistic about their time running out. Older people have learned to focus on things that make them happy
and let go of those that don't.
"People realize not only what they have, but also that what they have cannot last forever," she says.
"A goodbye kiss to a husband or wife at the age of 85, for example, may bring far more complex emotional responses than a similar kiss to a boy or girl friend at the age of 20."
