In general, the odds of being happy increased 5 percent with every 10 years of age [1].

Overall, about 33 percent of Americans reported being very happy at age 88, versus about 24 percent of those age 18 to their early 20s. And throughout the study years, most Americans reported being very happy or pretty happy. Less than 20 percent said they were not too happy.

Another reason to look on the bright side as we age. We'll be happier! Of course, my generation, baby boomers, seem to have a little trouble letting go of our goals and ambitions which can lead to unhappiness.
