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.

Our time in Paris has come to an end. It's time to get back to the greatest city in the world (Toronto). As has become customary around here, I'd like to summarize some of my anecdotal observations from the trip. Here goes:
The first one is an obvious one. Paris has transformed itself into a cycling city. Bold planning moves have explicitly prioritized biking, and you can feel it everywhere you go, including outside of the Périphérique. Young and old, families and individuals, everyone seems to cycle in Paris. In parallel to this, it feels like there has been a noticeable reduction in vehicular traffic. Many of the smaller streets around Paris almost feel like they've been pedestrianized. But in fact, it's just because there are so few cars.
Because of this change, I asked an Uber driver this past week if traffic has gotten worse and if it has generally gotten harder to drive in Paris. His response was absolutely. So I then asked him how Parisians generally feel about all of the changes and all of the new cycling lanes. The first part of his answer didn't surprise me. He said people who live in Paris love it because it's now easier to get around and they don't need to own a car. It's more efficient. But people who drive into the city or pass through it don't like it. Fair. However, as somebody who drives for a living, the second part of his answer did surprise me. He said, the changes needed to be done — bikes are a more efficient form of transport and they have greatly reduced pollution within the city. I thought this was quite an enlightened and selfless response.
The geography of Paris is changing. Parisians used to think of their city as only existing within the boundaries of the Boulevard Périphérique. (This is technically the boundary of Paris proper, but there is also the Métropole du Grand Paris, which encompasses the greater urban region.) New investments in transit, new developments, and pioneering urbanists are changing this mental model. A New Paris has arrived. And its modal split seems to be skewed toward non-car forms of mobility, to the point that younger Parisians don’t even seem to bother getting a driver’s license.
Anecdotally, I also noticed a big uptick in running, in the number of gyms/fitness studios in the city, and in the number of people walking around in athleisure wear. I view this as North American culture creeping in. Historically, my understanding is that running — and getting sweaty in public — was considered a bit of a faux pas. But at one point this week, I saw a parade of people running in and out of a Drip and doing laps down a busy street filled with cafés. Clearly, attitudes have changed.
Paris is, of course, well known for its cafés and terraces. But I would like to emphasize how beneficial these spaces are for the city. Every terrace comes equipped with a large awning that extends out into the street and creates a kind of outdoor room. These rooms then fill up with an endless supply of people facing outward, adding life, conversation, and eyes on the street. It's a wonderful way to create urban vibrancy, and you really feel the difference on streets where they don't exist. More cities need to figure out how to replicate this simple formula.
Food is different in Paris (and in Europe more broadly). There is real concern over the quality of ingredients and what we put in our bodies. We touched on this briefly, here. The difference is that you feel as if you can eat whatever you want, and the end result is that you feel satisfied, not gross. You also don't feel as if you've just ingested a sodium bomb.
On this trip, Bianca and I spent a lot of time exploring the 9ème, 10ème (where we were staying), and 11ème arrondissements, with regular trips south to Le Marais. We've now been to Paris enough that we're starting to figure out which areas we like the most. (If you have a favorite area, please leave it in the comments section below.)
Finally, I would like to end by saying that the trains in Paris are something they should be proud of. When we come to Paris, we always take the train into the city and, on this trip, we took the metro on a number of occasions to get out to places like Pantin and Boulogne. Not once did we wait more than a minute or two for a train. In fact, even during off-peak times, the maximum headway between trains seemed to be 4 minutes. With this at your doorstep, and with all the new cycling infrastructure that has been introduced, I guess it's no wonder that many Parisians couldn't care less about driving.
Until next time, Paris.
Yesterday, Bianca and I biked around 60 km from Cortina d’Ampezzo to Dobbiaco and then back again. It was the most beautiful bike ride that either of us had ever been on. Here's the Strava report.
Leaving Cortina, we were on a paved bike trail that had one side dedicated to cyclists and one side dedicated to pedestrians. The views of the valley were breathtaking — both the mountains and the community itself. It felt like we were riding through an idyllic mountain town that couldn't possibly be a real place.
The trail then switched to gravel and that's what we rode on through most of the mountains, including over bridges and through mountain tunnels. I couldn't tell you how many times we had to stop to take photos.
Our first official stop was for a picnic at Lago di Dobbiaco.
Here we were greeted by a bike counter. It was 13:11 and we were cyclist number 243 for the day. The counter for the year was acting up, but I'm guessing it was trying to say between 50-60k cyclists year to date. It was also here that we learned we were on a 560-kilometer trail that runs from Venice to Munich, all the way through the Alps. That would be a fun adventure for another day.
Overall, the cycling infrastructure was incredible. It was one of the things we were most impressed by. When we arrived in the predominantly German-speaking town of Dobbiaco — which is also known as Toblach in German — we were on a dedicated bike path that looked like this:
I couldn't even find any roads leading to some of the homes we were passing. It seemed like residents would have to drive their car onto the bike path just to get home. And once we arrived in the center of town, we were presented with bike lanes, like this, to take us around and underneath busy traffic roundabouts.
This is some of the most impressive biking infrastructure that I have ever experienced, and it's in a small town of 3,300 people. It's also an alpine town that gets bitterly cold winters — significantly colder than even cities like Toronto. So if they can make this happen, why can't we?
