Life expectancy

It was in northern Japan, a few years ago, that I first noticed the rhythm of walking was... slower. Not lazily so, but deliberate. People had time. The old man at the tofu stand poured miso soup with a kind of eternal gentleness, as if rushing it might shorten something sacred. Not just the soup. Life itself. I remember thinking: what if the pace of your street reflected the life span of its people?

What Are We Really Measuring?

Life expectancy. The term itself is suspiciously clinical—almost falsely calm, like the phrase “cost of living.” It sounds like a projection in an actuarial table, something one accepts with the same dispassion one accepts the boiling point of water. But look closer: life expectancy is a full-body mirror held up to a society. It reflects violence, sanitation, income, food, medicine, culture, peace, trust, roads, women’s rights, air quality, war, and refrigeration. It reflects everything.

Technically, it’s the average number of years a newborn is expected to live if current mortality rates persist. But the term hides the volatility under the average. It doesn’t say: if you are poor in Mississippi and Black, your life may end 15 years before your white neighbor. Or that if you're born female in Sierra Leone, your statistical future is written in maternal blood.

Longevity Is Unevenly Distributed

Monaco tops the world life expectancy charts. Eighty-nine years. Monaco! The tiny playground of the ultra-wealthy, bathed in medical abundance and champagne. Meanwhile, the Central African Republic trails near the bottom: 55 years. A chasm of 34 years—nearly two adult lifetimes between the world’s statistically longest and shortest human lives. That gap isn’t just numerical. It’s atmospheric. People in Monaco die of old age; people in CAR die of possibility stolen.

Japan, meanwhile, perennially hovers near the top, but that’s not just sushi and seaweed. There’s a whole philosophy of daily life—ikigai, walking, universal healthcare, rice measured by hand, not machine. And yes, the portion sizes matter. Even the bentos are balanced like diplomatic treaties.

In the United States, the richest country in human history, life expectancy is now declining. Not flat. Declining. For the first time in over a century, American babies can now expect to live shorter lives than their parents. A collapse brought on by opioids, gun deaths, untreated diabetes, suicides. And loneliness, which sounds soft but is hard on organs. There's no ICD-10 code for “chronic despair,” but maybe there should be.

Modernity Doesn’t Guarantee Immortality

It was easy to believe, sometime around 1995, that the future would just keep extending human lives—more pills, better diagnostics, robotic surgeries, personalized genomes. We saw charts curving upward and assumed the curve would go on forever. But longevity gains can plateau. Or reverse.

Cuba, for instance, has roughly the same life expectancy as the United States—despite being poorer by almost every conventional measure. Their secret? Universal healthcare. A dense network of community-based medicine. Doctors doing house calls. A deeply preventive system.

Then there’s Hong Kong. A city whose density, stress, and vertical living would suggest high cortisol and early death. And yet it boasts the longest life expectancy in the world for women: over 88 years. Here, one sees a peculiar mix—an Eastern diet, obsessive cleanliness, Confucian elder care norms, and brutal economic pressure coexisting.

It’s not simply wealth that extends life. It’s what you do with it.

The Shadow of Inequality

The United Kingdom, my own somewhat fractured homeland, is not exempt from the statistics of shame. A child born in a poor neighborhood in Glasgow can expect to live two decades less than one born in an affluent corner of London. Twenty years. That’s an entire adulthood lopped off by postcode. You can cross the River Clyde and lose the equivalent of your 60s and 70s.

Even within the same hospital in a major Western city, you’ll find life expectancy mapped along ethnicity, income, gender. There are two systems running in parallel, like dual bloodstreams—one gliding with early intervention and cautious diets; the other battered by delayed appointments, environmental toxins, and a resigned fatalism.

Aging Is Political

The politics of life expectancy are always quietly boiling. Pension systems, healthcare spending, voting blocs—all hinge on how long people live. A rapidly aging society like Italy or Japan must decide: will we tax the young more, raise retirement ages, automate eldercare, or import younger workers?

In China, where over 400 million people will be over 60 by 2050, the demographic crunch is a looming economic headache—and a cultural crisis. The Confucian obligation to care for one’s elders isn’t easily scaled to millions of isolated urban seniors. There are apartment towers now—silent and sunlit—where the old sit alone, staring out at a youth that left them behind.

Meanwhile, in sub-Saharan Africa, the opposite challenge. The median age in Niger is just 15. Youth surging. But infrastructure cannot keep pace. In many countries with rapidly growing populations, child mortality rates still inflate the life expectancy figures downward. And yet, hope is born in quantity, if not yet in quality.

Disease, War, and the Human Clock

Consider the shock events—the pandemics, the wars, the famines. These don’t just kill; they drag life expectancy down like a boulder tied to a helium balloon. The 1994 Rwandan genocide collapsed life expectancy in a matter of months. AIDS erased decades of gains across southern Africa.

COVID-19, globally, pulled the average life expectancy down by nearly two years between 2019 and 2021—the first universal drop since World War II. In the U.S., the hit was sharper—2.7 years lost in total, disproportionately among Black, Latino, and Indigenous communities. You could hear it in the breathlessness of an ER at midnight, in the quiet disappearance of grandparents from family tables.

But in a grim way, disease also shows us what systems work. South Korea, New Zealand, and Singapore weathered COVID with minimal life expectancy decline. Structure, discipline, investment, and public trust—a rare cocktail—proved as life-extending as any medicine.

The Hidden Contributors

Clean water. Road safety. Refrigeration. These aren't romantic, but they keep us alive.

In Peru, a study found that installing simple handwashing stations in rural villages reduced child mortality by over 40%. That’s not gene editing or AI diagnostics. That’s soap.

Traffic fatalities kill over 1.3 million people annually. That’s more than malaria. Life expectancy rises with better signage, slower speeds, and reflective jackets.

And diet, oh god, diet. In Italy’s Cilento region, old men still bike to markets, eat olive oil with their bread, drink small wines, laugh in the sun, and make it to 100. Meanwhile, in parts of the American Midwest, entire towns eat like carnival booths—funnel cakes, bacon-wrapped burgers, sweet tea the color of rust—and die before Medicare kicks in.

The Gender Imbalance

Globally, women live longer than men. This is near-universal, from Finland to Nepal. Why?

Biological factors play a role—estrogen has protective cardiovascular effects; women’s immune systems are generally more robust. But so do behavioral ones. Men are more likely to smoke, drink excessively, avoid checkups, die in accidents, and commit suicide. In Russia, for example, the life expectancy gap between men and women is 10 years. Ten.

There’s also the emotional reticence of men. The refusal to say, “I’m not okay.” Longevity requires vulnerability. Silence can kill.

An Anecdote, Unscientific But Honest

My grandfather died at 82, three years after my grandmother. She had been the organizer, the appointment-keeper, the cook. After she passed, he forgot to eat lunch. Not out of confusion—out of disinterest. When people say, “he died of a broken heart,” we roll our eyes. But maybe there’s something to it. Maybe life expectancy isn’t just about inputs and interventions. Maybe it’s also about company.

Extending Life vs. Expanding It

One final note, and this one sticks in the teeth a bit.

We often speak of extending life. But seldom of expanding it. The two are not identical. Extending life means adding years. Expanding life means making those years vibrant, autonomous, interconnected, and, ideally, pleasurable.

A bedridden 92-year-old, surrounded by beeping machines, is alive. But is that what we aspire to? Or do we mean the 84-year-old dancing barefoot in the Balearic dusk?

Longevity is not just about being less dead. It’s about more life.
