Daniel's thirty-seven, and he's been thinking about the fact that in a lot of historical periods, that would put him either in the ground or in the village elder chair. His question is whether the milestones compressed along with the life expectancy. Did people marry earlier, stop working earlier, get handed the wise-wistful-grumpy elder role in their thirties? Would you find a thirty-five-year-old retiree being consulted about the harvest because he'd seen it all? And before we can answer whether thirty-seven felt old, we have to fix the statistic everyone quotes.
Because the statistic is doing almost none of the work people think it's doing.
Right. Life expectancy at birth. Thirty-five years. Everyone's heard that number for some medieval or early modern population, and the mental image is a world of thirty-five-year-olds dropping dead in the fields.
And that image is wrong in a very specific, arithmetic way. The number is real, but it's not measuring what people assume it's measuring.
So let's unpack this. What does life expectancy at birth actually capture?
It's a summary of a period life table. You measure death rates at every age in a given window, then ask: if a hypothetical cohort of newborns experienced exactly those death rates at every age, how long would the average one live? That's e of zero. Life expectancy at birth.
And the average gets dragged down by the deaths that happen early.
Catastrophically. Infant mortality in a lot of pre-industrial populations ran twenty to thirty percent. Not in famine years, not in plague years. Baseline. Cumulative under-five mortality could hit forty, even fifty percent in bad conditions. So you're taking a hundred births, and thirty of them are dead before age five. Another ten or so by twenty. The arithmetic mean of the whole cohort collapses, even if the people who survive childhood mostly make it to sixty, seventy, sometimes eighty.
So the mean is being driven by dead children, not by a world where everyone's corpse is thirty-five.
That's exactly the mechanism. A life expectancy at birth of thirty or thirty-five can coexist perfectly comfortably with a conditional life expectancy at age twenty of another thirty-five or forty years. A twenty-year-old could reasonably expect to reach their late fifties or sixties.
Let's make that concrete. The toy cohort.
A hundred births. Thirty die by age five. Ten more die between five and twenty. So you've got sixty people entering adulthood. Now suppose those sixty mostly live to sixty, sixty-five, seventy. A handful die in their forties from accident or infection, a few more in their fifties. But the modal adult death is somewhere in the sixties. Now do the arithmetic on the whole cohort. The thirty who died at age zero or one or three contribute almost nothing to the total years lived. The average across all hundred births lands around thirty-five. But the average adult experience is nothing like thirty-five. The thirty-five is an artifact of mixing two completely different populations: children, who died in huge numbers, and adults, who often lived long.
And the number Daniel actually wants is e of thirty-seven. Conditional life expectancy at his exact age.
Which in most historical populations with decent records is not a death sentence. A thirty-seven-year-old man in, say, seventeenth-century England, if he'd survived childhood and wasn't a soldier or a sailor, had a reasonable shot at his sixties. Not guaranteed. The mortality curve for adults was still much steeper than today's. Infections killed people in their forties and fifties that we'd treat with antibiotics in an afternoon. But the idea that thirty-seven was old is just not what the demography shows.
And we should be honest about the exceptions, because they matter. Plague. War. Maternal mortality.
Maternal mortality is the one that breaks the "adults lived long" story, and it breaks it brutally. Women in their twenties and thirties died in childbirth at rates that would horrify any modern clinician. In some populations, maternal mortality was the single largest cause of death for women of reproductive age. So when we say a thirty-seven-year-old could expect to reach his sixties, there's a gender asymmetry hiding in there. The male thirty-seven-year-old had a decent outlook. The female thirty-seven-year-old had already survived a decade and a half of the most dangerous thing a pre-modern body could do.
And plague and war are episodic shocks on top of a baseline. They could kill adults in droves, absolutely. The Black Death killed maybe a third of Europe. But those are crises. They're not the everyday mortality structure. The everyday structure is: children die in huge numbers, adults die at a slow but steady trickle, and a minority of adults make it to genuine old age.
There's also a class gradient that people forget. Aristocrats, clergy, propertied men in stable regions had adult survival profiles that would not shock a modern actuary. A bishop in a quiet diocese, well-fed, not doing manual labor, no battlefield exposure, could live into his seventies or eighties. Meanwhile the urban poor, the enslaved, people in malarial regions, their adult mortality was much worse. So "life expectancy" wasn't one thing even within a single society. It varied by rank, by location, by occupation.
So the headline is: the short life expectancy story is mostly a story about dead children.
And the statistic everyone quotes is answering a question nobody actually asked. Daniel's asking what it felt like to be thirty-seven. The number he's been handed is answering what happened to the average newborn. Those are different questions with different numbers.
So the numbers say adults lived longer than the headline suggests. But did the milestones compress anyway? That's the next thing Daniel asked. Marriage, retirement, the elder role.
Marriage is the test case, and the answer is going to surprise a lot of people. In much of pre-modern Western Europe, there was something demographers call the European marriage pattern. Women married in their mid-twenties. Men in their late twenties. That's not earlier than today. In some places it's later than a lot of modern marriages.
And this is well documented from parish registers, tax records, household listings. The idea that everyone married at sixteen because they'd be dead by forty is backwards.
It's exactly backwards. The European marriage pattern was partly a response to land scarcity. You couldn't marry until you had the resources to support a household, which meant waiting until you inherited or accumulated enough. So marriage was delayed, not accelerated. The demographic clock wasn't ticking toward thirty-five in a way that made people rush.
Now, there were societies where girls married in their teens. But that wasn't because of short life expectancy. That was property, alliance, labor systems. Aristocratic families marrying off daughters at fourteen to seal a treaty. That's politics, not a response to mortality.
Right. And even in those cases, the marriage was early but the social role of the married teenager wasn't what we'd call adult in the modern sense. She was a pawn in a property arrangement. The question of whether she felt like an adult is a different question from whether she was married.
So marriage milestones weren't compressed by mortality. What about retirement?
This is where the category error gets really stark. Retirement as a life stage is largely a late nineteenth and twentieth century invention. It's tied to pensions, mandatory retirement ages, industrial labor. The idea that you work until sixty-five and then stop, with a pension, as a normal expected phase of life, that's Bismarck's Germany, that's the New Deal, that's the postwar welfare state. None of that existed in the seventeenth century.
So the thirty-five-year-old retiree Daniel's imagining is a category error. There was no institution to retire into. No pension system to fund it. Most people worked until they couldn't work anymore, and then they were cared for by family or they died.
And the few who did stop working early, they weren't called retirees. They were called gentlemen. Or rentiers. Or they were just rich. A propertied man in his thirties who didn't need to work wasn't a retiree, he was a landlord. The word retiree implies a system. The system didn't exist.
So the "retiree in his thirties" is almost entirely a myth. What about the elder role? Was a thirty-seven-year-old cast as the wise, wistful, grumpy elder?
Mostly no. And the reason is interesting. The elder role tracked survival scarcity, not age. In a village where very few people reached seventy, the actual seventy-year-old was rare. Rarity made that person socially marked. A thirty-seven-year-old was just a middle-aged adult with living parents.
This is the part I think is the most interesting. The wise elder archetype is partly a response to rarity. When almost no one makes it to seventy, the person who does is a statistical anomaly. They've outlived their cohort, they've seen things almost no one else has seen, they're a living archive. So the culture builds a role around them.
And that role is heavy. It's not just being old. It's being one of the few. The last surviving grandparent. The person who remembers the last famine. In a world where most people die before their grandchildren are born, the grandparent who's alive when the grandchild is fifteen is a rare and precious thing.
So the social weight of old age came from being one of few, not from a compressed timeline. It's scarcity of the very old, not abundance of the middle-aged, that created the elder mystique.
And that has a knock-on effect that I think is underappreciated. As life expectancy rose and the old became common, the cultural script for old age fragmented. You get retirement communities, ageism, the grumpy old man trope as comedy rather than reverence. When the seventy-year-old was rare, he was a sage. When seventy-year-olds are everywhere, they're just... And some of them are annoying.
The reverence was a scarcity premium. Once the scarcity disappeared, the premium collapsed.
And the role didn't go away, it just got redistributed. We still have wise elders, but now they're eighty-five, ninety, not sixty. The age at which someone counts as a genuine elder has moved up as longevity has increased. Daniel at thirty-seven in the modern world is nowhere near the elder role. In a seventeenth-century village, he also wouldn't be near the elder role. The elder role has always tracked the tail of the survival distribution, not the middle.
So the compression Daniel imagined is real in one sense, but it's the institutional life stages that are modern inventions. Retirement, pension, elder status as a formal category. The biology was never as compressed as the statistic suggested. The institutions were invented much later than people assume.
And that's the inversion. People think the past had compressed life stages because life was short. Actually, the past had fewer formal life stages because the institutions hadn't been invented yet. The compression is a modern artifact, not an ancient one.
Let's talk about what a thirty-seven-year-old actually was in, say, a seventeenth-century English village.
A thirty-seven-year-old man, if he was a farmer or a craftsman, was in his productive prime. He was probably married, probably had children, probably had living parents, maybe had a living grandparent if he was lucky. He was not a retiree. He was not an elder. He was the backbone of the labor force.
And if he was a woman at thirty-seven?
She'd survived the most dangerous reproductive years. She might have had eight or ten pregnancies and buried three of the children. She was probably running a household, doing domestic labor, maybe working in the fields during harvest. She was not wistful. She was exhausted.
The wistful grumpy elder is a luxury of a society where old age is common enough to have a personality.
The grumpy old man as a stock character requires a society where being old is common enough to be mundane. In a world where the seventy-year-old is the only one in the village, you don't make jokes about him. You ask him what the winter of 1607 was like.
And he tells you, and you listen, because no one else alive remembers.
The reverence and the comedy are two sides of the same coin. Both are responses to the demographic reality. When the old are rare, they're revered. When they're common, they're characters.
So what does Daniel actually get from this? He's thirty-seven, and he's been imagining himself as either dead or ancient in the past. The honest answer is neither.
In most historical periods, a thirty-seven-year-old man who'd survived childhood was a middle-aged adult, probably with living parents, in a world where the very old were rare and therefore culturally marked. He wasn't dead, and he wasn't the village elder. He was the guy doing the work.
And the "dead by thirty-seven" thing, that's the statistical illusion. The number that says thirty-five is answering a question about newborns, not about him.
Right. The number he should care about is e of thirty-seven. Conditional life expectancy at his exact age. And in most historical populations with decent records, that number was a lot more than zero.
Let me ask you something, Herman. You're a retired pediatrician. You spent a career watching children survive things that would have killed them in the past. Does that change how you read the historical numbers?
It does, because I've seen the mechanism in miniature. When you reduce infant mortality, life expectancy at birth shoots up, even if nothing changes for adults. That's what happened in the twentieth century. Life expectancy at birth in the United States went from about forty-seven in 1900 to about seventy-seven by the end of the century. Most of that gain came from children not dying.
Not from adults suddenly living to a hundred and fifty.
Right. Adult life expectancy moved, but not nearly as dramatically. The headline number was transformed by the collapse of child mortality. So when people say "people used to live to thirty-five," what they're really saying is "children used to die at rates that would break your heart."
And that's the thing the statistic hides. It converts a tragedy of childhood into a false claim about adulthood.
The dead children are invisible in the headline. The number just says thirty-five, and everyone imagines a world of thirty-five-year-old corpses. The reality is a world of tiny graves and long adult lives.
So let's go back to Daniel's actual questions one by one. Did people marry earlier? In much of pre-modern Europe, no. The European marriage pattern delayed marriage to the mid-twenties or later.
And where marriage was early, it was driven by property and alliance, not by mortality.
Did people retire earlier? No. Retirement as an institution didn't exist. Most people worked until they couldn't. The propertied few who stopped working early were gentlemen, not retirees.
And the thirty-five-year-old retiree is a category error. There was no system to retire into.
Would you find retirees in their thirties filling the wise elder role? No, because the elder role tracked the rarity of the very old, not the age of the middle-aged. A thirty-seven-year-old was just a middle-aged adult.
The elder was the person who'd outlived almost everyone else. That was a seventy-year-old, not a thirty-seven-year-old.
So the compression Daniel imagined is real in one sense, but it's the institutional life stages that are modern inventions, not the biological ones.
And the biological ones were never as compressed as the statistic suggested. The statistic was lying, or rather, it was answering a different question than the one people thought they were asking.
Let's talk about the European marriage pattern a bit more, because I think it's the most counterintuitive finding here.
It's one of those things that flips the popular imagination. The stereotype is that people in the past married young because life was short. The reality in northwest Europe was that people married in their mid to late twenties, which is later than a lot of modern marriages. The reason was economic. You needed a household, which meant land or a trade, which meant waiting.
And this pattern had consequences. It kept population growth in check. It created a pool of unmarried young adults who worked as servants and laborers. It shaped the whole social structure.
And it's a reminder that "the past" is not one thing. Different regions had different marriage patterns. Eastern Europe, for example, had earlier marriage. The Mediterranean had its own patterns. The European marriage pattern is specific to northwest Europe, and it's the one most people are implicitly thinking of when they imagine the pre-modern West.
So even the premise that "people married earlier in the past" is only true in some places, and for reasons that have nothing to do with life expectancy.
The demographic clock wasn't driving marriage timing. Economics and property were.
Let's talk about the invention of retirement, because I think that's the other big inversion.
Retirement as a mass phenomenon is a product of the late nineteenth and early twentieth centuries. Bismarck introduced the first old-age pension in Germany in the eighteen-eighties. The United States got Social Security in the nineteen-thirties. Before that, old-age support was a family matter, or a charity matter, or a matter of just keeping working until you dropped.
And the idea of a fixed retirement age, sixty-five, that was originally an actuarial convenience, not a biological observation. Someone picked a number that made the pension math work.
Then the number became a social fact. Sixty-five became "old" because the pension system said so, not because biology said so. The institution created the life stage, not the other way around.
When Daniel imagines a thirty-five-year-old retiree in the past, he's projecting a modern institution backwards onto a world that didn't have it.
The projection fails. The past had rich people who didn't work, but they weren't retirees. They were rentiers, landlords, gentlemen. The word "retiree" implies a career that ended, a pension that began, a system that recognized the transition. None of that existed.
The closest thing to a retiree in the pre-modern world was probably a monk or a nun. People who left the world and were supported by a community. But that was a religious vocation, not a life stage.
The monastery was a kind of retirement institution, but it was chosen, not assigned by age. A forty-year-old who entered a monastery wasn't retiring from a career, he was changing his life.
The past didn't have compressed life stages. It had different life stages, shaped by different institutions.
The institutions we think of as natural—retirement, adolescence, the empty nest—those are all recent inventions. The past wasn't a compressed version of the present. It was a different thing entirely.
Let's go back to the elder role, because I think that's the most emotionally resonant part of Daniel's question. He's imagining being the wise, wistful, grumpy elder at thirty-seven. And the answer is no, but the reason is interesting.
The reason is that the elder role was a scarcity premium. When almost no one reached seventy, the person who did was a living archive. They'd seen things no one else had seen. They remembered the last famine, the last war, the last time the river flooded. So the culture built a role around them, a role of reverence and consultation.
The role wasn't assigned by age alone. It was assigned by survival. You had to outlive your cohort to become the elder. A thirty-seven-year-old hadn't outlived anyone. His parents were probably still alive. His grandparents might be alive. He was in the middle of the pack, not the tail.
The elder was the tail of the survival distribution. The person who'd made it to the far end. And in a world where the far end was rare, that person was precious.
The wise elder archetype is partly a response to rarity. It's not that people in the past aged faster. It's that surviving to old age was rare, and rarity created mystique.
As the old became common, the mystique evaporated. You can't revere every seventy-year-old when there are millions of them. The role fragmented. Some old people became sages, some became grumpy old men, some just became people.
The grumpy old man trope is a luxury of a society where old age is common enough to be mundane. In a world where the seventy-year-old is the only one in the village, you don't make jokes about him.
You ask him what the winter of 1607 was like.
He tells you, and you listen, because no one else alive remembers.
The compression Daniel imagined is real in one sense, but it's the institutional life stages that are modern inventions, not the biological ones. The biology was never as compressed as the statistic suggested. The institutions were invented much later than people assume.
The statistic was doing something sneaky. It was converting a tragedy of childhood into a false claim about adulthood.
The dead children are invisible in the headline. The number just says thirty-five, and everyone imagines a world of thirty-five-year-old corpses. The reality is a world of tiny graves and long adult lives.
What's the honest answer to Daniel's question? In most historical periods, a thirty-seven-year-old man who'd survived childhood was a middle-aged adult, probably with living parents, in a world where the very old were rare and therefore culturally marked. He wasn't dead, and he wasn't the village elder. He was the guy doing the work.
The "dead by thirty-seven" thing, that's the statistical illusion. The number that says thirty-five is answering a question about newborns, not about him.
The number he should care about is e of thirty-seven. Conditional life expectancy at his exact age. And in most historical populations with decent records, that number was a lot more than zero.
Let me add one more wrinkle. The class gradient. We've been talking about averages, but the experience of a thirty-seven-year-old aristocrat was completely different from a thirty-seven-year-old laborer. The aristocrat might have another thirty years ahead of him. The laborer might be broken by work and disease by forty.
The enslaved person's life expectancy was a different universe entirely. The transatlantic slave trade created mortality conditions that were worse than almost anything in the pre-modern world. Adult slaves on Caribbean sugar plantations had life expectancies that were short, not just statistically short.
The answer to Daniel's question depends on who he's imagining himself as. A seventeenth-century English farmer? He's fine. An enslaved person on a sugar plantation? He's in one of the worst mortality environments in human history.
The statistic hides that too. A single life expectancy number for a whole society flattens the class gradient into one misleading average.
The class gradient is where the real suffering was. The headline number of thirty-five was produced by dead children and dead slaves and dead laborers. The aristocrat living to seventy was in the same average as the laborer dying at forty.
The number isn't just misleading about age. It's misleading about class.
The life expectancy statistic is a lossy compression of human experience. It takes a complex distribution of suffering and survival and flattens it into one number that everyone misreads.
The misreading has consequences. People look at the past and think it was a world of young corpses, when it was actually a world of dead children and long-lived survivors, with brutal inequality in between.
The past was worse than the present in almost every way, but it wasn't worse in the specific way the life expectancy statistic suggests. It wasn't a world where everyone died at thirty-five. It was a world where children died at horrifying rates, and the adults who survived often lived long enough to see their grandchildren.
The grandchildren were the reward. The elder role, the reverence, the consultation, that was the payoff for surviving. You got to be the archive.
Now the archive is everywhere. Everyone's a seventy-year-old with a story. The scarcity premium is gone.
What happens to the elder role now that the old are common? That's the open question.
I think the role is still there, but it's been pushed up the age distribution. The genuine elder now is ninety, not seventy. The person who's outlived almost everyone they knew. The person who remembers a world that's gone.
That person is still rare. The ninety-year-old is still a statistical anomaly, even in a world where seventy is mundane.
The elder mystique hasn't disappeared. It's just moved. The scarcity premium now attaches to the very old, not the merely old.
Which means Daniel at thirty-seven is even further from the elder role than he would have been in the past. In the seventeenth century, he was a middle-aged adult. Now he's barely out of young adulthood.
The life stages have stretched, not compressed. Adolescence extends into the twenties. Young adulthood extends into the thirties. Middle age starts at forty-five or fifty. The elder role is reserved for the old.
The compression Daniel imagined is the opposite of what actually happened. The past had fewer formal life stages, but the biological ones weren't compressed. The present has more formal life stages, and they're stretched out.
The compression is a modern artifact. We invented adolescence, retirement, the empty nest, the golden years. Those are all recent creations. The past didn't have them, but not because life was short. Because the institutions hadn't been invented yet.
The institutions were invented in response to rising life expectancy, not the other way around. Retirement exists because people started living long enough to need it.
Bismarck didn't create old age. He created a system to fund it.
Let's talk about the maternal mortality point, because I think it's the one place where the "adults lived long" story breaks down.
It's the brutal exception. Women in their twenties and thirties died in childbirth at rates that would horrify any modern clinician. In some populations, maternal mortality was the single largest cause of death for women of reproductive age. So when we say a thirty-seven-year-old could expect to reach his sixties, there's a gender asymmetry hiding in there.
The male thirty-seven-year-old had a decent outlook. The female thirty-seven-year-old had already survived a decade and a half of the most dangerous thing a pre-modern body could do.
The danger didn't end at thirty-seven. Women continued to die in childbirth into their forties. The maternal mortality rate was a constant background threat for the entire reproductive span.
The life expectancy statistic hides a gender gap too. Women's life expectancy at birth was often similar to men's, but the causes of death were completely different. Men died of violence and accident and occupational hazards. Women died of childbirth.
The childbirth deaths were concentrated in the twenties and thirties, exactly the ages Daniel is asking about. A thirty-seven-year-old woman in the past had survived something that killed a significant fraction of her cohort.
If Daniel were asking about a thirty-seven-year-old woman, the answer would be more complicated. She wasn't an elder, but she was a survivor.
She was a survivor of the most dangerous thing a pre-modern body could do. That's not the same as being old, but it's not nothing.
The life expectancy statistic doesn't capture any of that. It just says thirty-five, and everyone imagines a world of thirty-five-year-old corpses.
The statistic is a lossy compression of human experience. It takes a complex distribution of suffering and survival and flattens it into one number that everyone misreads.
What's the one thing Daniel should take from this?
The one thing is that the number he's been handed is answering a question he didn't ask. Life expectancy at birth is about newborns. His question is about thirty-seven-year-olds. And the number for thirty-seven-year-olds is a lot more than zero.
The elder role was never about being thirty-seven. It was about being rare. The wise elder was the person who'd outlived almost everyone else. That was a seventy-year-old, not a thirty-seven-year-old.
Daniel at thirty-seven in the past would have been a middle-aged adult with living parents, doing the work, and not particularly remarkable. The remarkable person was his grandparent, if he had one.
The grandparent was remarkable because he was rare. Scarcity created the mystique.
Which is a strange inversion of what Daniel imagined. He thought the past compressed the elder role into the thirties. Actually, the past reserved the elder role for the old, and the old were rare.
The compression was in the statistics, not in the society.
The statistic was lying.
Or rather, it was answering a different question than the one people thought they were asking.
The honest answer to Daniel's question is: no, you probably wouldn't have been dead, and no, you probably wouldn't have been an elder. You'd have been a middle-aged adult in a world where the very old were rare and therefore culturally marked.
The "dead by thirty-seven" thing is a statistical illusion. The number that says thirty-five is about dead children, not about you.
The dead children are invisible in the headline.
The headline is wrong about what it implies.
The next time someone says people used to live to thirty-five, the correct response is: no, children used to die at rates that would break your heart, and the adults who survived often lived long enough to see their grandchildren.
The grandchildren were the reward.
The grandchildren were the reward.
Let's talk about something that's been nagging at me. The phrase "wise, wistful, and maybe a little grumpy." That's a very specific archetype. Where does that come from?
It's a modern archetype. The grumpy old man is a stock character in comedy. He's the guy who's seen it all and is annoyed by everything. He's wistful about the past and grumpy about the present. And he's usually played for laughs.
But in a world where the old were rare, that archetype couldn't exist. You couldn't play the elder for laughs. He was too important.
The grumpy old man is a luxury of a society where old age is common enough to be mundane. When seventy-year-olds are everywhere, you can make jokes about them. When the seventy-year-old is the only one in the village, you ask him what the winter of 1607 was like.
The archetype Daniel is imagining, the wise, wistful, grumpy elder, that's a modern projection. The past had wise elders, but they weren't grumpy. They were revered.
They weren't thirty-seven. They were seventy.
The grumpiness is a modern addition. It's what happens when reverence decays into familiarity.
Familiarity breeds contempt, and contempt breeds comedy.
The archetype Daniel is imagining is a modern creation projected backwards onto a past that wouldn't have recognized it.
The past had sages. It didn't have grumpy old men. The grumpy old man is what happens when the sage becomes common.
The sage became common because life expectancy rose.
The grumpy old man is a side effect of progress.
That's a very strange conclusion.
It's the kind of thing this show exists to notice.
Let's sum up. Daniel asked whether life milestones compressed when life expectancy was shorter. The answer is no, and the reason is that life expectancy at birth is a misleading statistic.
The headline number of thirty-five is dominated by infant and child mortality. Adults who survived childhood often lived into their sixties and seventies.
Marriage wasn't earlier. In much of pre-modern Europe, it was later than modern assumptions.
Retirement didn't exist. It was invented in the late nineteenth and twentieth centuries.
The elder role wasn't assigned to thirty-seven-year-olds. It was assigned to the old, who were rare and therefore revered.
The compression Daniel imagined is a statistical illusion, not a historical reality.
The historical reality is more interesting than the illusion. It's a world of dead children and long-lived survivors, of brutal inequality and scarce elders, of institutions that hadn't been invented yet and roles that were shaped by scarcity rather than age.
The past wasn't a compressed version of the present. It was a different thing entirely.
The difference is hidden in the statistic.
The statistic is a lossy compression of human experience.
The next time someone says people used to live to thirty-five, the correct response is: no, children used to die at rates that would break your heart, and the adults who survived often lived long enough to see their grandchildren.
The grandchildren were the reward.
The grandchildren were the reward.
I keep thinking about the toy cohort. A hundred births. Thirty dead by five. Ten more by twenty. Sixty adults, most of them reaching their sixties. The mean is thirty-five, but the modal adult death is sixty-five.
The mean is a lie about the mode.
The mean is a lie about the mode. That's the whole episode in one sentence.
The lie has consequences. It makes people think the past was a world of young corpses, when it was actually a world of dead children and long-lived survivors.
The dead children are invisible in the headline.
The headline is wrong about what it implies.
The next time someone says people used to live to thirty-five, the correct response is: no, children used to die at rates that would break your heart, and the adults who survived often lived long enough to see their grandchildren.
The grandchildren were the reward.
The grandchildren were the reward.
We're circling. Let's move on.
Agreed.
What's the open question? If the wise elder role was a response to scarcity, what happens to that role now that the old are common?
I think the role is still there, but it's been pushed up the age distribution. The genuine elder now is ninety, not seventy. The person who's outlived almost everyone they knew. The person who remembers a world that's gone.
That person is still rare. The ninety-year-old is still a statistical anomaly, even in a world where seventy is mundane.
The elder mystique hasn't disappeared. It's just moved. The scarcity premium now attaches to the very old, not the merely old.
Which means Daniel at thirty-seven is even further from the elder role than he would have been in the past. In the seventeenth century, he was a middle-aged adult. Now he's barely out of young adulthood.
The life stages have stretched, not compressed. Adolescence extends into the twenties. Young adulthood extends into the thirties. Middle age starts at forty-five or fifty. The elder role is reserved for the old.
The compression Daniel imagined is the opposite of what actually happened. The past had fewer formal life stages, but the biological ones weren't compressed. The present has more formal life stages, and they're stretched out.
The compression is a modern artifact. We invented adolescence, retirement, the empty nest, the golden years. Those are all recent creations. The past didn't have them, but not because life was short. Because the institutions hadn't been invented yet.
The institutions were invented in response to rising life expectancy, not the other way around. Retirement exists because people started living long enough to need it.
Bismarck didn't create old age. He created a system to fund it.
The honest answer to Daniel's question is: no, you probably wouldn't have been dead, and no, you probably wouldn't have been an elder. You'd have been a middle-aged adult in a world where the very old were rare and therefore culturally marked.
