You suffer more aches and pains. Your middle is expanding, your hairline receding, and new wrinkles seem to pop up like dandelions. Sooner or later, you're bound to get bad news from the doctor. And you're happier than you've been in years.
Wait -- what?
That's right, studies by organizations including the General Social Survey, the Pew Research Center and the Gallup Poll indicate that people in their 50s, 60s and 70s are in better spirits than younger adults. Generally speaking, happiness is high when one enters one's 20s, slides downhill through the 30s and 40s, and swoops up again after 50, continuing to soar for several decades.
Graphed across an average lifetime, the happiness timeline looks like a U-shaped curve. (Some call it a W, to account for the slight rise in the 30s before it dips down again -- experts suspect this represents parents who are enjoying the brief respite between their kids' Terrible Twos and Even Worse Teens.)
Age is just one factor researchers have associated with happiness. Others include income, health, marital status, religiosity and political affiliation. (These are correlations, by the way, not cause-effect relationships -- for example, if married people are happier on average it could be because marriage makes people happy, or because happy people are more likely to be married.)
But unlike, say, wealth, the link between happiness and older age doesn't really make intuitive sense. Why would we grow more cheerful as we lose health, vitality, looks and friends?
Experts aren't sure, though theories abound, said University of Minnesota psychologist Angus W. MacDonald, who teaches a course on happiness.
One possibility, MacDonald said, is that people typically spend early- to mid-adulthood stressing over their life goals: building a career, getting married, having and raising children. Later, having achieved those goals -- or content to have passed them up -- people can relax into a sense of satisfaction.
