Around the world, happiness tends to peak later in life. It has more to do with balancing priorities than elderly wisdom


The Global Decline in the Mental Health of the Young
One of the major findings in wellbeing research until recently was that happiness was U-shaped by age and unhappiness hump-shaped by age. There was a midlife crisis — a finding reported in well over 600 published papers using data on 145 countries. It was present in both developing and developed countries. And it was persistent over time. The finding of a peak in ill-being in midlife was consistent with Anne Case and Angus Deaton’s work on mortality and the so-called “deaths of despair.”1 In the US in particular and to a lesser extent in other countries, White prime-aged individuals without a college degree had high death rates from suicide, drug overdoses, and cirrhosis of the liver. Drug overdose deaths in the US, for example, peaked at midlife ages. In 2023, the Centers for Disease Control and Prevention (CDC) reported that overdose death rates per 100,000 by age rose from 13.5 for 15-to-24-year-olds to 45.6 for 25-to-34-year-olds and 60.8 for 35-to-44-year-olds, and then declined to 53.3 for 45-to-54-year-olds, 49.2 for 55-to-64-year-olds, and 14.7 for those over the age of 65.2 The morbidity data matched the mortality data.

Use it or lose it: How cognitive skills change with age
Cognitive skills are commonly assumed to begin deteriorating from the age of 30, which could pose a significant challenge for rapidly ageing populations. But this assumption relies largely on cross-sectional data that cannot distinguish between ageing patterns and cohort differences. Using German longitudinal data, this column finds that skills, on average, increase markedly into one’s 40s before decreasing slightly in literacy and more severely in numeracy. In addition, skills decline at older ages only for those with below-average skill usage, outlining a clear policy pathway for avoiding skill declines.

Open source confronts its midlife crisis | The Observation Deck
Midlife is tough: the idealism of youth has faded, as has inevitably some of its fitness and vigor. At the same time, the responsibilities of adulthood have grown: the kids that were such a fresh adventure when they were infants and toddlers are now grappling with their own transition into adulthood – and you try to remind yourself that the kids that you have sacrificed so much for probably don’t actually hate your guts, regardless of that post they just liked on the ‘gram. Making things more challenging, while you are navigating the turbulence of teenagers, your own parents are likely entering life’s twilight, needing help in new ways from their adult children. By midlife, in addition to the singular joys of life, you have also likely experienced its terrible sorrows: death, heartbreak, betrayal. Taken together, the fading of youth, the growth in responsibility and the endurance of misfortune can lead to cynicism or (worse) drastic and poorly thought-out choices. Add in a little fear of mortality and some existential dread, and you have the stuff of which midlife crises are made…
