Most of us have heard of the so-called "Blue Zones." These are the parts of the world where there is an exceptionally high number of centenarians — people over the age of 100. We've talked about this topic before, covering the importance of things like diet, community, and constant moderate physical activity. But I would like to reiterate just how impactful our physical environments can be on our overall well-being.
The island of Sardinia is one of the world's Blue Zones. But it's not actually the entire island of Sardinia; it's a specific inner mountain region that is the Blue Zone. And in this region, at least two things are fascinating: First, the men have some of the longest average life expectancies in the world and second, the men live just as long as the women do. This is unique. Ordinarily, women outlive men. But not here.
The data overwhelmingly suggests that this outcome is the result of topography and employment. Because it is a mountainous region, the built environment is filled with steep inclines and staircases everywhere you go. The result is that even walking down the street to go to church or the grocery store results in organic moderate physical activity.
At the same time, the men in this region have historically worked as shepherds. This meant that work also involved walking up and down hills all day. Again, more organic moderate physical activity. Because of this, research has found very significant correlations between longevity and pastoralism, the average slope of the territory, and the average daily distance required to reach work. The steeper the better.
There's little mystery here. We know that more activity is better for us than less. The challenge is that we can't all live in bucolic mountain towns and chase sheep around all day. Modern society demands a lot of sitting and typing and vibe coding. We also have a market economy that is constantly looking for ways to make our lives more convenient so that we're able to do even more sitting around.
We try to compensate for this with gyms and other fixes (“Urban Cycles” cover image by Marcellus Hall):

But the better and more fundamental solution is organic moderate physical activity. Meaning, moderate physical activity that we don't have to actively seek out, and that is organically embedded throughout our everyday lives. It's best when it's a lifestyle. And this is one of the reasons why I view cities where walking and cycling are ingrained as a great luxury. All else being equal, these places are destined for better health outcomes.
If I look up my Apple Health data for 2025, there are very clear spikes in steps whenever I'm traveling. This makes sense. It's because I like going to places where I can walk around all day and be physically active. I can only sit on a beach for so long. But it's also ironic that modern life dictates that I have to go on vacation in order to be more active. That's not how Blue Zones work.
There is no greater luxury than our health. Without it, nothing else matters. And so I think it behooves us to make it a fundamental component of city building.

Over the weekend I learned about Dan Buettner’s Blue Zones. These are cities and parts of the world where, according to Dan, people have a much longer life expectancy. The five regions he identifies as Blue Zones are: Okinawa (Japan); Sardinia (Italy); Nicoya (Costa Rica); Icaria (Greece); and Loma Linda (California).
Many of you have probably heard of this finding from Malcolm Gladwell. I think he writes about it in Outliers. I had. But I didn’t know about Dan Buettner and his efforts to teach these “secrets” to other regions around the world.
I can’t speak for the efficacy of his consulting practice, but I think it’s interesting that some of the characteristics of these Blue Zones include a strong sense of family and community, as well as constant moderate physical activity. In other words, activity that is integral to normal life, such as lots of hills in a mountain town.
The links between urban form, walking and biking (instead of driving), and health outcomes are something that get a lot of air time. It is, of course, one of the reasons why denser cities are thought to be healthier cities. They encourage more active forms of mobility.
But what else could we be doing to make physical activity an inseparable part of urban life? In Rio de Janeiro, they often incorporate fitness facilities into their public spaces, whether it’s a parklet or the beach. That probably doesn’t qualify as inseparable, but it’s certainly a start.
