According to researchers at Harvard, the age of 35 is the happiest, as that's when most of us begin to stabilize our lives, reach professional heights, and have stronger social ties—all of which contribute to our sense of total fulfillment. 23, 35, 70... In the end, there's no single definitive answer.
Surprising Science: The 2 Ages When People Are Happiest
According to a study by the London School of Economics and Political Science, happiness tends to peak not once, but twice in life: first at age 23, and again at age 69. Yes—69!
The observed age pattern for daily stress was remarkably strong: stress was relatively high from age 20 through 50, followed by a precipitous decline through age 70 and beyond.
Unhappiness is hill-shaped in age and the average age where the maximum occurs is 49 with or without controls.
Most established adults we interviewed seemed to recognize that they were happier in their 30s than they were in their 20s, and this impacted how they thought about some of the signs of physical aging that they were starting to encounter.
Early in life, of course, we still are growing, and expanding the number of cells that we have. The cells are aging, but so slightly that we can't see it: we just see the body growing and developing. At some point in life, often in the 30's, the tell-tale signs of aging begin to be apparent.
Health. Young/prime adulthood can be considered the healthiest time of life and young adults are generally in good health, subject neither to disease nor the problems of senescence. Strength and physical performance reach their peak from 18 to 46 years of age.
A huge research study concluded that in developed countries, people start having decreasing levels of happiness starting at age 18. It continues in their 20s and 30s before reaching an unhappiness peak — or bottoming out, if you prefer — at the precise age of 47.2.
There are a lot of different reasons why you might feel like nothing makes you happy. Certain mental health conditions like depression, anxiety, and PTSD can cause severe feelings of unhappiness, lack of motivation, and disinterest in activities that used to bring joy.
This knowledge about happiness states that 50% of our happiness is determined by genetics, 10% by our circumstances and 40% by our internal state of mind. This rule originates from the book “The How Of Happiness” written by Sonja Lyubomirsky. A lot of people and even psychologists live by this rule.
In it, he talks about how the ages of 22–42 are statistically the most unhappy period in life. Why? People come out of their early 20s and think life is supposed to be easy, but it's not. Those two decades are full of challenges.
Recent research shows that members of the Baby Boomer generation have worse health than previous generations did at the same ages—diabetes, heart disease and other chronic illnesses are more common.
Quality of life increases from 50 years (CASP‐19 score 44.4) to peak at 68 years (CASP‐19 score 47.7). From there it gradually starts to decline, reaching the same level as at 50 years by 86 years. By 100 years, CASP‐19 score has declined to 37.3.
According to this unscientific survey, most women peak between 19.9 years and 24.0 years (sample size 22).
They also found that happiness across lifespan exists on a spectrum of valleys and peaks over time: Satisfaction with life declines between ages nine and 16, rises to reach its peak at age 70, then declines again until age 96 (the oldest age recorded in the study).
According to researchers at Harvard, the age of 35 is the happiest, as that's when most of us begin to stabilise our lives, reach professional heights, and have stronger social ties—all of which contribute to our sense of total fulfilment.

The Quarter-Life Awakening
Turning 26 and going into 27 is one of those ages that feels like a bridge between two worlds. You're no longer in the carefree, experimental years of your early 20s, but you're not yet in the more settled, “adulting” world of your 30s.
