Here is what they found:

After our early twenties, happiness declines on the way to our mid-fifties; then, after cycling back up through our late sixties, it falls again once we reach 75. If you're having a midlife crisis, better days are coming! The turnaround point is 55, at which point happiness starts climbing once again.

Mental attitudes play an important role: Another recent study published in the Journal of Research in Personality that analyzed thousands of people across nearly four decades of life, age 16 and up, found that extroverted, emotionally stable younger adults were happier in retirement than young adults who'd experienced an emotionally turbulent early adulthood.

Of course, figuring out what makes you happy or improving unhappy life circumstances are a big help.
