“Drink more water” might be the most common health advice there is. It’s good advice — but the reason it matters goes deeper than most people realize, and it connects directly to how your cells function. Water isn’t just something that keeps you from feeling thirsty. It’s the medium every cellular process happens in. Think … Read more
Almost everyone past a certain age describes some version of the same thing: they just don’t have the energy they used to. The usual advice is more sleep, more coffee, more B vitamins, maybe an energy drink. Some of that helps at the margins. But most of it treats energy as something you top up … Read more
Inside almost every cell in your body are structures called mitochondria. (Mature red blood cells are the notable exception — they drop theirs to carry more oxygen.) They’re the power plants — they take the food you eat and the oxygen you breathe and turn it into the energy your cells actually run on. When … Read more
People occasionally ask what I actually do — not the science, but the practical day-to-day. I’m 61, I feel better than I did in my 40s, and I’m happy to lay out the real routine. There’s no secret in it, and the boring foundations matter far more than any single product. Sleep comes first. I … Read more
Here’s something that genuinely surprised me when I first read the research, and it flips a common assumption on its head. When you exercise, your muscles produce reactive oxygen molecules — the very things antioxidant marketing tells you to fear. And it turns out those molecules are a required part of how exercise makes you … Read more
People ask me regularly what I do to maintain my health. I’m 61, I do demanding physical work, I recover quickly, and I don’t carry the signs of aging that many people my age do. So the question is understandable. I try to be honest and specific rather than giving a list of things that … Read more
Energy is one of the most common health complaints. Not the dramatic fatigue of illness, but the everyday sense of running below capacity — needing more coffee than you used to, hitting a wall in the afternoon, not having the reserves you remember having a decade ago. The conventional response to this is to look … Read more
Athletes are among the most scientifically demanding consumers in the health space. Performance is measurable. Recovery time is measurable. Endurance, strength, and reaction time are all measurable. When something works, athletes know it. When it doesn’t, they know that too. That’s why the growing interest in redox signaling among serious athletes is worth paying attention … Read more
Most people track how they feel in broad strokes. Good day. Bad day. Tired. Energetic. Foggy. Clear. These are the categories most of us use to describe our daily experience of health. What’s happening underneath those categories is far more specific — and far more interesting. Every subjective experience you have of your own body … Read more
