Canada must become a global superpower
The silver lining to the US starting a trade war with Canada and regularly threatening annexation is that it has forced this country out of complacency. Indeed, I'm hard pressed to remember a time, at least in my lifetime, when patriotism and nationalism has united so much of Canada. According to a recent survey by Angus Reid, the percentage of Canadians expressing a "deep emotional attachment" to the country jumped from 49% in December 2024 to 59% in February 2025. And as further evidence of...

The bank robbery capital of the world
Between 1985 and 1995, Los Angeles' retail bank branches were robbed some 17,106 times. In 1992, which was the the city's worst year for robberies, the number was 2,641. This roughly translated into about one bank robbery every 45 minutes of each banking day. All of this, according to this CrimeReads piece by Peter Houlahan, gave Los Angeles the dubious title of "The Bank Robbery Capital of the World" during this time period. So what caused this? Well according to Peter it was facil...
The story behind those pixelated video game mosaics in Paris
If you've ever been to Paris, you've probably noticed the small pixelated art pieces that are scattered all around the city on buildings and various other hard surfaces. Or maybe you haven't seen or noticed them in Paris, but you've seen similarly pixelated mosaics in one of the other 79 cities around the world where they can be found. Or maybe you have no idea what I'm talking about right now. Huh? Here's an example from Bolivia (click here if you can't see...

Because my blog emails go out at 6AM every morning, many people think that I am up at 4AM every day typing away at my computer and drinking coffee. I do not get up this early. In fact, I’m naturally more of a night person. But since our world is heavily biased against night people, I do what I can to conform.
Perhaps because of this, I am very interested in sleep optimization. I have a Fitbit that I occasionally use, but I seem to go through phases with it. I think part of the problem is that the data I get from it doesn’t feel like enough.
This week I was intrigued to learn about something called the ŌURA ring. Yes, it’s another sleep and activity tracker. But it does some unique things. And because it’s a ring, it’s in constant contact with your finger’s arteries. So presumably the data is better.
The ring’s output appears to be centered around something called “readiness”, which the company refers to as “an optimal physical and mental state that can be achieved by acquiring the ultimate balance between sleep and activity.”
To give a more concrete example, the ring tracks something known as heart rate variability (HRV). Fitbit and Apple devices don’t do this, but supposedly it’s quite a telling datapoint. Professional sports teams are starting to track this so they know how “ready” the players are.
I’m not yet sure I’m ready to invest in the ring (they start at USD$299), but I am definitely intrigued.
If you’d like to read more about “the science” behind it, you can do that here. If you’d like to watch a mini-review, click here. And if you’re ready to pull the trigger, you can use the coupon code “kevinrose” to get 25% off. I discovered the ring via his newsletter.
