Travel without flying

I am not a tourist. I try to live as locally as possible to blend into the culture and environment. It helps, at least, with my Spanish, which has improved substantially. Being surrounded by the language makes you absorb words and phrases almost subconsciously. However, this immersive approach isn’t always healthy at least not when your goal is longevity. Street food? Maybe delicious, definitely not healthy. Especially when you’re standing next to the grill, inhaling the smoke of a thousand tacos al pastor. Pollution in Mexico is no joke. I still don’t know how I survived Mexico City. Sleeping there felt like army training for chemical warfare the kind where you have to sleep with your gas mask on. And so did I. I actually wore mine at night as well, because being indoors didn’t make much difference not for me, and not for my Atmotube device, which I carry with me all the time to monitor air quality. Poor thing was probably begging for mercy. And those fumes! Old cars with exhausts tha...

After my recent speed of aging test done through the Blueprint company founded by Bryan Johnson, I found out that I’m aging at a speed of 0.63x. So what does that mean? It means that for every year that passes, I age only 0.63 of a biological year. In other words, my aging is about 37% slower than normal. Imagine watching a movie at 63% speed while everyone else watches it at full speed when they’re rolling the credits, I’m still somewhere in the middle of the story. 😅 That’s basically my life right now. Others accumulate biological “damage” faster, while I seem to be taking the scenic route to aging. So… Who Am I? I’ve been vegan since May 2014, and I figured out early that it was one of the best choices for health, animal well-being, and climate impact. It wasn’t only about what’s on my plate it was about being aware of how my actions echo through the system. Being mindful of the world around me also helped me understand the rise of AI. After all, AI is a human creation our digital ...

  I’ve now been to several places in the U.S. New York, St. Louis, Dallas and San Antonio and I can say I had a real cultural shock . After living in Sweden and Canada (Montreal), the U.S. feels like the far edge of the spectrum in terms of urban planning, culture, safety nets, food, roads and public transport. Basically everything looks and feels exactly as chaotic as it seems and I expected more from the world’s biggest economy. Let’s be fair: the U.S. is enormous. But still, numbers are numbers. USA GDP per capita: $89,105 Sweden GDP per capita: $74,900 Some might argue the U.S. is too big to keep everything as neat, clean, and well-organized as Sweden. But let’s look at my own invented metric GDP per square kilometer : USA: $3,102,347 / km² Sweden: $1,775,902 / km² So by this measure, the U.S. has almost double the dollars per square kilometer . Yet paradoxically the roads are full of potholes old buildings are collapsing next to fancy hotels and “newly built”...

Globalized World We live in a strange contradiction. On one hand, humans invented nations, borders, religions, gender roles, and money, concepts so “real” they exist mostly in our collective imagination. On the other hand, local societies often had to endure very real hardships: closed-minded living, few opportunities, and self-imposed cages of limitation. Then, for a glorious moment, salvation seemed near: the internet arrived, international organizations popped up, borders softened, and the “Union of Countries” type projects promised free movement. The world felt open. Of course, nothing global comes without side effects. Alongside global trade and collaboration came global tax loopholes, worldwide criminal syndicates, and scams that can now reach everyone, everywhere, from anywhere . Online Scams 2.0 Online fraud isn’t new. What is new is how easy it’s become. In the beginning, only a few highly skilled nerds knew how to exploit digital cracks in the system. Today? Anyone with a Wi...

  Simulation Creates Realities I can see a near future where humans stop smashing things in real life just to see what happens. No more expensive crash tests, no more wind tunnels sucking up billions of dollars, no more logistic and production nightmare on construction site or “oops, we broke another robot.” Instead, simulations will do the heavy lifting. Immense AI databases will crunch the properties of materials down to the atomic level and give us the most precise outcome imaginable. And honestly we’re already halfway there. Today, companies use AI to simulate how robots move, or to teach one how to do a backflip. Is that a useful feature? Probably not. But hey, at least it’s cheaper to fail in virtual reality than in the factory, where “oops” means six months of repairs and a crying engineer. The result? Fewer broken robots, fewer wasted weeks, and a lot more laughing at digital screw-ups before trying them in real life. We are heading into a world where we trust the s...

Hello, world long time no see 😊s ince January 2021, when I paused blogging, it feels like I lived another life. On the road I met an amazing girl who became my wife. We moved from place to place and eventually landed in Stockholm, Sweden, where routine and daily challenges took over. We divorced about half a year ago for for the same reason many couples divorce, the usual mix of personality, feelings, and mindset. In the same time, I got deep into tracking and improving my health, and the wave of new AI tools surprised us all with what they can do. The pace of change is crazy. In these four years my awareness grew a lot, and since June 2025 I’m back on my path, exploring new places. What’s best for whom when crossing the ocean                Today I’m in Canada. I didn’t take the “usual” way I would’ve liked I took the plane. As a curious note, flying pumps out far more CO₂ than a sailboat would, and it adds a bit of extra radiation to the...
