We built a world for people who die on time. Now that they aren’t, nobody quite knows what to do.
In 1900, the average human life in Western Europe lasted around 47 years. By 2024, it had reached 81. In the span of a single century, we essentially handed humanity an extra lifetime — and then changed the subject.
The science made the leap. The culture did not. And the gap between those two facts is where a strange, mostly unacknowledged awkwardness now lives.
Consider what ‘old age’ actually means today. A 70-year-old in good health may have 20 or 25 functional years remaining — more time than it takes to raise a child, build a company, or earn two degrees. And yet the architecture of that life, its social scripts, financial instruments, professional opportunities, and cultural representations, was largely designed in an era when 70 was genuinely the end of the story.
We have not built institutions for long lives. We have patched short-life institutions until they barely hold.
THE RETIREMENT PROBLEM
The modern concept of retirement was invented by Otto von Bismarck in 1889, when Germany introduced the world’s first state pension. The eligibility age was 70. Average life expectancy in Germany at the time was 45. Bismarck was not designing a period of leisure. He was designing a benefit almost nobody would collect.
The pension system that descended from that moment — and that forms the backbone of social security infrastructure across most developed economies — was built on the same implicit assumption: retirement is short, expensive, and actuarially manageable precisely because most people won’t reach it, and those who do won’t stay long.
That assumption is now structurally broken. In Japan, where 29% of the population is over 65, the government has quietly begun encouraging people to work into their 70s, not as a luxury but as a fiscal necessity. In the United States, the Social Security trust fund is projected to face shortfalls by 2033 under current contribution and benefit structures. The European Union’s old-age dependency ratio — the number of people over 65 relative to those of working age — is forecast to nearly double by 2070.
The numbers are not obscure. What’s obscure is why the cultural and institutional response has remained so hesitant, so incremental, so reluctant to name what is actually happening: the foundational bargain of the 20th-century welfare state — work hard, retire at 65, die within a reasonable timeframe — no longer describes the lives most people in wealthy countries are actually living.
THE IDENTITY VACUUM
The financial problem is tractable, at least in theory. The identity problem is harder.
Work is not merely how people earn money. For the majority of adults in developed economies, it is a primary source of structure, social connection, purpose, and self-definition. When Erik Erikson mapped the stages of human development in the 1950s, he ended at ‘late adulthood’ — a stage defined by the tension between integrity and despair. He did not map what comes after, because nothing was expected to.
Now there is a period that gerontologists sometimes call the ‘third age’ — the decades between functional retirement and physical decline. It can last 20 years. It is the longest unscripted chapter in most people’s lives, and society has almost nothing to say about how to live it well.
We have named the crisis without building the alternative. Long life is the offer. What it’s for is still up for negotiation.
The consequences show up in unexpected places. A 2023 study published in The Lancet found that social isolation among adults over 60 is associated with a 26% increased risk of dementia. A separate body of research from the Harvard Study of Adult Development — the longest study of adult life ever conducted — found that the quality of relationships at midlife was a stronger predictor of health and happiness in old age than cholesterol levels. The data keeps arriving at the same conclusion: long lives need meaning and connection to function. And the institutional infrastructure for meaning and connection after 65 is, by any honest assessment, thin.
THE LONGEVITY ECONOMY’S BLIND SPOT
There is, of course, enormous commercial energy being directed at longevity. The global longevity market — a category spanning everything from senolytics to continuous glucose monitors to elite wellness retreats in Switzerland — is projected to exceed $600 billion by 2030, according to the Global Wellness Institute. Bryan Johnson spends $2 million per year attempting to reverse his biological age. David Sinclair’s research on sirtuins and NAD+ precursors has sold millions of books and spawned an industry of supplements.
This is not nothing. The science is serious. Some of it will prove out. But the longevity economy has a consistent blind spot: it is almost entirely focused on extending the healthspan of people who are currently wealthy, currently healthy, and currently motivated to optimise themselves. It has very little to say about the 70-year-old former assembly-line worker in Łódź or Lyon who outlived his professional identity by a decade and has no roadmap for what comes next.
The question the longevity industry has not adequately answered is not ‘how do we live longer?’ It is ‘what do longer lives actually require, institutionally, culturally, and economically, to be worth living?’
That is a harder question. It doesn’t fit neatly on a supplement label or a venture capital deck. But it is the real design problem of the coming century — and whoever starts building for it seriously, rather than aspirationally, will be operating in genuinely unexplored territory.
The longest awkward age in human history is already underway. Most of us just haven’t admitted, yet, that we don’t know how to live it.
