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.

Last week in Japan was the first time I had ever driven a car on the left side of road. I spent a summer working in Dublin many years ago but I never once drove while I was there.
To be honest, I thought it was going to be more awkward than it was. But other than accidentally turning on the wipers a few times (they were on the opposite side to where turn signals typically live), it came to me pretty quickly.
I also noticed that left-hand traffic seems to impact the flow of many other things in Japan. On sidewalks, for example, people walk on the left. And on escalators, everyone stands on the left (and walks on the right), whereas the opposite tends to be true in Toronto.
Japan is also an orderly and rule-abiding place and so these conventions are widely followed. On more than a few occasions, I realized I was swimming upstream and then quickly switched sides.
What’s interesting is how this directional convention permeates so many aspects of everyday life. Which begs the question: where and when did it start? Do the "rules of the road" always influence everything else?
The answer seems to be that nobody really knows. There are many unproven theories. Some suggest that it has to do with how horses were ridden and walked, and that ~90% of people are right-handed.
But I couldn’t find anything definitive. What we do seem to know, at least anecdotally, is that once a side is chosen, it broadly impacts how people generally move around. Pay attention the next time you're on a busy sidewalk.
Let's resume looking at sidewalks and public spaces.
If you look in the City of Toronto's Official Plan for the stretch of Dundas Street West that runs between Dupont Street and Bloor Street West, you'll find a map that looks like this:

Let's resume looking at sidewalks and public spaces.
If you look in the City of Toronto's Official Plan for the stretch of Dundas Street West that runs between Dupont Street and Bloor Street West, you'll find a map that looks like this:
Red signifies "Mixed Use." And so if you were to just look at this map, you might naturally assume that, in the real world, this is a continuous main street that connects The Junction neighborhood down to Bloor. But that's not actually the case. Instead, it looks like this:
Because of the rail corridor on the east side, it is a single-sided street. And generally speaking, these don't make for the best retail streets. But it also has narrow sidewalks and a compromised public realm. If you go back to the map I shared yesterday, you get this:
I don't think 30cm is entirely accurate here, but that's beside the point. What matters is that this is just one of many examples in the city of a discontinuous public realm. (Here's another, undignified example, from Parkside Drive.)
Over the years, there have been a number of design concepts proposed. Below is one by Brown + Storey Architects that was done I don't know how many years ago. Their proposal widened the sidewalks along this stretch, and added bike lanes. They also proposed a roundabout at the intersection of Dundas, Dupont, and Annette, which is another matter that needs addressing.
But none of this has been implemented and I don't know of any plans to do it. When we were going through the rezoning process for Junction House, we were made aware of some transportation studies that had been done for the above intersection. But that's about it. There wasn't an actual ETA.
However, now that my commute consists of walking up and down this part of Dundas, I've been thinking more about how it could be improved.
I think there's no question that the sidewalks need to be widened. It would also be helpful if there were crosswalks to facilitate getting off the south end of this exotic island:
But equally important, I think that something should be done about the single-sided nature of the street. Given that there's limited width, my mind immediately goes to shipping containers, or something similar, to start activating the east side of the street.
This has already been done further south on Dundas (east of Bathurst):
And it could work here too. Already there's a Blondie's Pizza anchoring the south end of this stretch (really fantastic pizza, by the way):
But I would love to hear your ideas, as I'm currently in the market. I also don't think that you necessarily need to be from Toronto in order to comment. Great streets are great streets. So if it were up to you, what would you change, if anything, about this part of Dundas Street West? Let me know in the comment section below.
