Longevity Cities Series — Part One
Longevity is often imagined as the domain of labs, biotech startups, or Bryan Johnson–style protocols. But the most powerful engine of healthy longevity today is far older, broader, and much more familiar: The City.
Cities are where our environments, behaviors, stress levels, mobility patterns, air quality, wages, social networks, and public institutions intertwine to shape how long — and how well — we live. They are the world’s largest biotechnologies: intricate sociotechnical systems that influence health more profoundly than any available medical intervention. And they are also the primary sites where any future breakthroughs — including those that might finally push humanity beyond the Calment Limit, the long-standing world record of 122 years and 164 days — will take root and scale.
This essay introduces The Longevity City: a technoprogressive framework for remaking urban life so that cities can systematically expand the longevity dividend — the economic and social benefits that emerge when more people live longer, healthier lives.
Importantly — as Part Two will explore — this framework is not speculative. The essential components already exist in cities around the world. Our task, therefore, is not to invent a new paradigm from scratch, but to weave existing models into a coherent, longevity-focused civic architecture, and then push the conversation towards a more democratic innovation model for actualizing the next stage of breakthroughs.
This essay is a call for technoprogressives to take the lead in maximizing our longevity potential using every tool available — in the cities, towns, and regions where we already live and work. And if you don’t yet identify as a technoprogressive, consider this framework an invitation into the practical work of building a future where healthy longevity is a public good, accessible to all.
Why Cities Are the Future of Longevity
Cities regulate the primary determinants of health: air, water, mobility, social participation, safety, wages, rest, heat exposure, social networks, and stress. Modern public health emerged from cities — sanitation systems, vaccination programs, emergency medicine, public health agencies, and crisis response infrastructures.
Nearly every major improvement in lifespan was forged through urban networks of doctors, researchers, planners, labor organizers, and civic movements.
Cities remain the world’s engines of scientific and civic innovation.
If healthy longevity — or Longevity 2.0 — is going to emerge, it will follow the developmental pathways of Longevity 1.0. It will take root in the dense, collaborative, richly infrastructured terrain of the modern city.
Public Health Maximalism: A New Paradigm for Urban Governance
The foundational principle of The Longevity City is simple:
Every urban system is a health system.
Housing, transportation, wages, childcare, school quality, pollution exposure, neighborhood design, digital infrastructure — all of these shape lifespan and healthspan.
To maximize the number of quality-adjusted life years (QALYs) available today, we have to treat cities as unified systems of systems — capable of fostering healthy longevity through a paradigm I call public health maximalism.
Public health maximalism reinterprets public health according to its most expansive and scientifically grounded definition. Instead of focusing only on disease prevention, it treats public health as the coordinating logic for how cities design policy, deploy interventions, and build grassroots demands.
This gives us a shared evidentiary foundation — standardized metrics rather than vague appeals to “well-being” or “flourishing.”
A few principles illustrate what this looks like:
Systems are interconnected
Transit influences pollution, which affects cardiovascular health, but it also shapes land use, mobility, stress, and economic opportunity. Small design choices cascade across systems.
Public health must be a protocol, not a department
Public health should no longer be confined to a regulatory silo. It must become the standard that governs decisions in housing, labor, transportation, climate, policing, technology, and more.
Coalitions multiply
Labor organizers, disability justice advocates, urbanists, Vision Zero campaigns, climate planners, and child- and elder-friendly city proponents all benefit from a public-health-first urbanism.
Public health maximalism creates shared terrain for powerful, technoprogressive municipal coalitions.
The Social Longevity Gap: The Crisis We Can Solve
Within any metropolitan area, life expectancy often varies 20–30 years across neighborhood lines. These disparities are not genetic. They are the result of structural inequalities in policy, infrastructure, and opportunity.
Layered on top of this is the expanding red zone — the number of years people spend alive but not healthy. Across the world, healthspan is failing to keep up with lifespan, putting immense strain on families, workers, and healthcare systems. In many countries, this divergence is becoming an existential threat to social and economic stability as populations age rapidly.
These twin crises — the neighborhood longevity gap and the healthspan gap — are among the defining public health challenges of the 21st century. Left unaddressed, they could produce catastrophic demographic pressures.
But they also reveal one of the most powerful opportunities for technoprogressive municipal governance. If cities can close these gaps — extending healthspan, reducing inequality, and compressing the red zone — they will generate enormous social, economic, and ethical dividends.
The Longevity City offers a roadmap for doing exactly that.

I very much enjoyed this essay because it shifts longevity from an individual biomedical challenge to an emergent property of an urban socio-technical system. That is precisely the level at which many of our greatest gains in health have historically occurred.
From a systems science perspective, however, one question naturally follows: How do cities discover where to intervene?
In complex systems, leverage points are rarely intuitive. Optimizing transportation may improve air quality, but also employment, stress, social participation, and healthcare access. Investing in parks may reduce chronic disease, strengthen community ties, improve mental health, and even stimulate local economic activity. The challenge is not simply recognizing that "everything is connected," but identifying which interventions produce the greatest systemic effects under local conditions.
My experience with Structured Democratic Dialogue suggests that this cannot be solved by experts alone. When citizens, scientists, practitioners, businesses, and policymakers collectively map the influences among obstacles and opportunities, they consistently identify high-leverage actions that no single discipline could have predicted. Equally important, they create the ownership and trust needed for implementation.
Perhaps the defining characteristic of a true Longevity City will not simply be better technology or better healthcare, but better collective intelligence.
The healthiest cities of the future will not necessarily be those with the best hospitals or the smartest AI. They will be the cities that learn fastest.
So what are the components that will create this sort of city?
The interesting thing about this idea, is that it’s only really possible if you turn cities into carbon sinks which generate their own renewable energy, and biodiversity hotspots where trees and vines (clean the air alongside tech/materials which do this) and agroforestry are integrated into the city. Engineering and growing infrastructure systems using both hard engineering and biota- plants, fungi, microbes and reedbeds for grey water purification for instance, or make them 15-min walkable cities with lots of neighbourhood identity, opportunities for sub-culture activities, and many communal outdoor and indoor spaces where people and Nature can thrive together, exercise together, do arts and music and gatherings together are also needed. A city is the sociotechnical organism by means of which purpose can be lived. So the purpose of a longevity city might be to enable the purposes of its citizens, which entail the very particularities and differences that collectively express its identity.
Without clear cultural identities, and lots of arts and street life, cities die. When administrative modes/behaviours do not align with the inhabitants collective and community’ ethos, cities lose their ability to adapt and be self-sustaining.
One also needs viable cybernetic governance which can allow boroughs to self-regulate with a high degree of autonomy, and infrastructure that is non-siloed, data coordinated across systems, and operational initiatives with very clear outcomes.
And a happy city is where people feel they have a direct say in how their borough is run, and that it serves their local priorities and needs.
Furthermore, to maintain their neighbourhood “Umweldt” it must monitor what matters particularly to their vision of what quality of life means, and what “expression” of architecture, people and Sense of Place is meaningful to them. That includes its history as a living complex sociotechnical cultural organism, so to speak.
Creating these niche-multi-domain environments drives feedback loops to culture and economics, which then changes the nature of life as it’s lived in that city (Singapore). The city then affords creativity, scientific inquiry, ingenuity, exchange and trade, happiness and a healthful life. It engenders in its co-making, a sense of Belonging. A sense of being part-of something inspiring and energising, where anyone can thrive.
For this to be possible, you need parallel forms of Open Money, ways in which neighbourhoods can “sense” what’s going on amongst their own “open measure” platforms which allow folk to transparently record say, # baby birds born, # kindly acts of x type, and so forth. But it gets even more interesting when you start looking at how Open Money systems can amplify relational activities in local boroughs/neighbourhoods, thus increasing city and national currency economic activity.
Of course cities like Lille in Belgium are drawing their local farmers closer in to directly serve the food needs of its citizens. All of this encourages good behaviour of local ‘polluting/neglectful’ companies as they eat the food and drink the water that’s locally produced too.
It gets even more interesting Ito behaviours which orient towards the greater-good while allowing each person to satisfy basic needs and build businesses. Ethics norms arise from relation, connection and aren’t so abstract as to be meaningless.
However, without an integrated information system-of-systems, where nature and cities and energy systems are brought into coherent coordination, healthful prosperous longevity will be unattainable.
There are many studies demonstrating that it’s the sustained stress of poverty, few opportunities, unaffordable education and skills training, and polluted environment which make folk more susceptible to illness for the last 2-3 decades of life. I’ve some idea what it will do if we don’t step-in and decide what we value more highly, but unemployment and loss of identity and sense of being valued and being able to contributed and be socially acknowledged (respect, independence, status etc) for it this coupled to longer life will drive stress higher and increase poor diet. This may well then reduce lifespan and health. However, before we worry about how long we live, and how healthily, ought we not to first consider children and the sorts of “habitats” they thrive in?
Once each city has discovered its “shared values” - what matters the most for itself and its place ito cultures, bioregional location, historical and Ito economic activities & possibilities and its people and children, this vision shapes individual activity towards coherent creation and implementation of the very concept.
Shanghai has decided it is the City Of A Thousand Parks. Apparently one can hear crickets chirp and songbirds sing EV has made the centre so clean and pleasant.
