We tend to think of dementia as something that either happens to you or it doesn't. A genetic lottery, maybe, or just the cruel arithmetic of getting old. But the science tells a more interesting, and honestly more hopeful, story. It turns out that the brain is not a passive bystander in its own decline. And the concept sitting at the heart of that story is cognitive reserve. This isn't fringe thinking. It's one of the more robust ideas to emerge from neuroscience in the past

There's a particular kind of diet culture that doesn't look like diet culture. It doesn't involve calorie counting or bikini-body promises. It comes dressed in the language of healing, of gut health, of listening to your body. It shows up in wellness blogs and functional medicine clinics and your friend who swears she finally feels like herself again after cutting out gluten, dairy, soy, corn, eggs, and - just to be safe, nightshades. This is elimination dieting. And it can b

Three conditions that look almost identical from the outside, and are routinely confused even by clinicians. Understanding how they diverge might be the most useful thing you learn about your own health this year. Let's start with a question that's probably crossed your mind, or the mind of someone you know: Am I burnt out, am I depressed, or is something else going on entirely? The honest answer is that those three categories overlap more than our tidy diagnostic labels like

If you've been anywhere near health news for the last few decades, you've probably felt that specific kind of exhausted cynicism that sets in after the tenth time the rules change. Fat is bad. No wait, fat is fine. Carbs are the enemy. Actually, it's sugar. Eggs will destroy your heart. Eggs are a superfood now. Butter is terrible. Butter is back. At some point you just want to throw your hands up and eat a cheeseburger out of spite. I get it. But I think that frustration, as

Cold plunges have had quite the glow-up over the past decade. What used to be the domain of Scandinavian athletes and masochistic weekend warriors has become a mainstream wellness ritual, complete with influencer endorsements, purpose-built tubs, and a library of podcast episodes where someone inevitably credits ice baths with transforming their life. And look, some of the enthusiasm is warranted. There's real, interesting biology happening when you submerge yourself in cold

Most people are at least vaguely familiar with the idea that some of us are morning people and some of us are night owls. But the science of chronotypes runs considerably deeper than personal preference or habit, and the implications for how we structure our cognitive work, physical training, and even social lives are more specific and actionable than most people realize. Let's dig into what's actually going on under the hood, and more importantly, what you can do with that k

The Problem With Testing Everything More Data Doesn't Mean Better Health There's a billion-dollar industry built on a simple and deeply appealing idea: the more you know about your body, the healthier you can be. And look, I get it. When you're handed a report with 80 values and your name on the top, it feels like personalized, cutting-edge medicine. It feels like you're ahead of the curve. But here's the uncomfortable truth - most of it is noise. That's not me being cynical

A clear-eyed look at which genetic variants genuinely change how you should eat, and which ones are mostly marketing. The pitch is irresistible: spit in a tube, send it off, and get back a personalized roadmap telling you exactly what to eat, what to avoid, and which supplements your unique genetic code supposedly demands. Precision nutrition at the DNA level. It sounds incredible, and honestly, part of it actually is real. The problem is that the marketing has sprinted about

The fitness world throws around "overtraining" like it explains everything. But there's a real difference between being run down and your body actually breaking down - and it matters. We've Normalised Being Wrecked Somewhere along the line, feeling terrible became a badge of honour in fitness culture. You're always tired? Grinding. Constantly sore? Dedicated. Can't sleep, irritable, performing worse every week? Clearly, you're just working hard. But here's the thing, there's

We've All Been Sold a Dream The pitch is irresistible: forget generic food pyramids and one-size-fits-all diet advice. Your DNA, your gut bacteria, your glucose tracker, they all hold the secret to the perfect diet, custom-built for your body. In a world where personalized medicine is becoming a real thing, why wouldn't personalized nutrition be right around the corner? Here's the honest answer: the science is genuinely exciting, but what's being sold to most people right no

Why the Most “Boring” Cardio Might Be the Most Powerful Longevity Tool We Have Intensity Is Overrated (At Least for Longevity) We've been sold on the idea that a good workout has to hurt. The harder you push, the more you're doing for your health, right? The fitness world rewards the dramatic: interval sprints, max-effort classes, anything that leaves you gasping on the floor. It feels like progress because it feels like suffering. But here's the uncomfortable truth: when sci

Fatigue Is More Than Just Being Tired I'll be honest: for a long time, I think the medical world got fatigue badly wrong. We've had a habit of slapping a psychological label on anything we couldn't easily explain; "stress," "depression," "deconditioning." And for millions of people dealing with crushing, relentless exhaustion, that dismissal has done real damage. But research over the last decade or so has been quietly building a much more compelling case. What if chronic fat
