Happiness peaks at age 23 and again at age 69, according to a wide-ranging study just completed by the Centre for Economic Performance at the London School of Economics.
The study surveyed 23,161 individuals between ages 17 and 85 and found that life satisfaction was highest for those at ages 23 and 69.
According to researchers, people in their early twenties overestimate their future life satisfaction by an average of around 10 percent, before the disappointments of life kick in.
As people pass through the next decades, they face declining expectations, hitting their low point during their mid-fifties, when researchers say regrets over unrealized dreams are at their highest.
But then satisfaction levels start to rise again after age 55, peaking at age 69.
According to a report in the London Daily Mail, the U-shaped happiness pattern has been observed in more than 50 nations and across both class and financial divides, but the CEP paper is the first to examine how our expectations compare to reality at different life stages.
Based on the study, Rolling Stones rocker Mick Jagger is at the peak of satisfaction, the golden age of 69.
