Despite all of the loss associated with aging: the ability to reproduce, physical strength and agility, pigment in our hair, elasticity in our skin, our children at home, our parents, and on and on, the results of a large Gallup poll recently released has found that by almost any measure, people get happier as they get older, and researchers are not sure why.

“It could be that there are environmental changes,” said Arthur A. Stone, the lead author of a new study based on the survey, “or it could be psychological changes about the way we view the world, or it could even be biological — for example brain chemistry or endocrine changes.”

The telephone survey, carried out in 2008, covered more than 340,000 people nationwide, ages 18 to 85, asking various questions about age and sex, current events, personal finances, health and other matters. The survey also asked about “global well-being” by having each person rank overall life satisfaction on a 10-point scale.

Finally, there were six yes-or-no questions:

Did you experience enjoyment during a large part of the day yesterday? 
 
Did you experience happiness during a large part of the day yesterday? 

Did you experience stress during a large part of the day yesterday? 

Did you experience worry during a large part of the day yesterday? 

Did you experience anger during a large part of the day yesterday? 

Did you experience sadness during a large part of the day yesterday? 

The answers, the researchers say, reveal “hedonic well-being,” that is, a person’s immediate experience of those psychological states, unencumbered by revised memories or subjective judgments that the query about general life satisfaction might have evoked.

On the global measure, people start out at age 18 feeling pretty good about themselves, and then, apparently, life begins to throw curve balls. They feel worse and worse until they hit 50. At that point, there is a sharp reversal, and people keep getting happier as they age. By the time they are 85, they are even more satisfied with themselves than they were at 18.

In measuring immediate well-being — yesterday’s emotional state — the researchers found that stress declines from age 22 onward, reaching its lowest point at 85. Worry stays fairly steady until 50, then sharply drops off. Anger decreases steadily from 18 on, and sadness rises to a peak at 50, declines to 73, then rises slightly again to 85. Enjoyment and happiness have similar curves: they both decrease gradually until we hit 50, rise steadily for the next 25 years, and then decline very slightly at the end, but they never again reach the low point of our early 50s.

Andrew J. Oswald, a professor of psychology at Warwick Business School in England, who has published several studies on human happiness, called the findings important and, in some ways, heartening. “It’s a very encouraging fact that we can expect to be happier in our early 80s than we were in our 20s,” he said. “And it’s not being driven predominantly by things that happen in life. It’s something very deep and quite human that seems to be driving this.”

The study was not designed to figure out which factors make people happy, and the poll’s health questions were not specific enough to draw any conclusions about the effect of disease or disability on happiness in old age. But the researchers did look at four possibilities: the sex of the interviewee, whether the person had a partner, whether there were children at home and employment status. “These are four reasonable candidates,” Dr. Stone said, “but they don’t make much difference.”

So, if things seem hard right now, take heart. The good news is we are aging! And really, that is fabulous considering the alternative. I always say, I am not afraid of getting old. I am afraid of not getting old!
