Is Your Watch Predicting Your Death?
What Biologic Age Really Means — and What It Doesn’t My Whoop tells me I’m eight years older than I actually am. Naturally, that raises a question. Does that mean I’m going to die eight years sooner? Is my watch quietly chiseling a new date onto my tombstone? Fortunately, the answer is no. Still, confusion around biologic age has exploded. Wearables promise insight. Apps offer scores. Some even whisper about your future health, as if destiny lives on your wrist. So let’s slow this down and talk about what biologic age really is — and why it matters far less than you think. The Two Numbers and the Dash Every tombstone has two numbers. One marks when you were born. The other marks when you died. However, the most important part isn’t either number. It’s the dash in between. That dash represents your life. It reflects your health, mobility, independence, and curiosity. When we talk about longevity, we shouldn’t obsess over the second number. Instead, we should focus on making those two numbers far apart — and keeping the dash strong for as long as possible. That’s healthspan.
Why Biologic Age Sounds Scarier Than It Is Biologic age is not a prophecy. It isn’t a death clock. It doesn’t predict how long you’ll live. Instead, biologic age is a model. It estimates how your body is functioning right now based on things like: resting heart rate heart-rate variability sleep duration and consistency activity and recovery patterns sometimes weight or blood pressure
Different devices use different inputs. As a result, they often give different answers. In other words, biologic age reflects recent stress and behavior, not your destiny. Think of it as feedback — not fate.
Why Your Watch Isn’t Measuring “Real” Aging Earlier in the Fork U longevity series, we talked about telomeres. Those shorten slowly over decades, one cell division at a time. Your wearable isn’t tracking that. Instead, devices like Whoop measure physiology, not DNA. They detect how hard you’ve been living lately, not how much time you have left. A bad week of sleep, travel, stress, or alcohol can push your biologic age higher. A calm, consistent routine can bring it back down. That’s not aging. That’s load management.
A Simple Experiment That Tells the Whole Story Here’s a trick I tried. I told Whoop I was younger than I actually am. Guess what happened? Suddenly, my biological age dropped below my real age. That alone tells you everything. Whoop isn’t predicting where you’re going. It’s comparing how you’re doing relative to the age you told it you are. Once again, that’s feedback — not destiny.
Why I Prefer Withings I use multiple devices because, frankly, I’m a nerd. However, I tend to prefer Withings for one simple reason. They don’t try to scare you. Instead of telling you how old you “really” are, Withings focuses on things that actually improve your life today: blood pressure trends body weight and composition heart rhythm sleep duration long-term consistency
More importantly, they ask better questions. Are you sleeping better? Is your blood pressure improving? Are your habits trending in the right direction? That’s medicine. Not numerology. And no — Withings didn’t pay me to say that.
The Biggest Mistake People Make Many people treat biologic age like a grade. Others see it as a moral judgment. When the number drops, they feel virtuous. When it rises, they panic. That framing misses the point. The only question that matters is this: Is it moving in the right direction over time? One bad week doesn’t define you. One good week doesn’t either. Trends matter. Moments don’t.
What No Device Can Tell You No wearable can tell you: when you’ll die whether you’ll get cancer if you’ll have a stroke how many years you have left
Anyone claiming otherwise is selling fear — or subscriptions. Technology can guide behavior. It cannot predict destiny.

With all the spices we have access to, it is amazing how bland recipes have become. I have many cookbooks, some from great chefs, television personalities, and friends. What I am always surprised by is how bland the food has become. People seem to think a bit of salt, pepper, maybe onions, and garlic provide the spices one needs. Perhaps it is because some associate spice with heat. Mostly because many have never experimented with some of those great warm spices available. A pinch of coriander, some freshly ground cumin, a little cardamom, or a touch of cinnamon can turn an ordinary dish into something remarkable. And the most astonishing part is that these spices financed voyages around the world, built cities, created fortunes, and caused people to kill one another. Without the spice trade, it is safe to say that the United States, as we know it, would be vastly different from what it is now. The money loaned to the United States, when we were a fledgling country, came from the wealthy spice merchants from what was considered one of the great hyperempires of the world, based in Amsterdam. But before we go to the birth of the United States, let me take you to the meatball.

MesoAmerica and Chocolate In our series looking at foods that built civilizations, today we are going to stay in the Americas with chocolate. Chocolate has been used as currency, consumed by kings, incorporated into religious ceremonies, and prescribed as medicine. Today, it is a multibillion-dollar industry that wants you to believe that eating chocolate is an act of preventive cardiology. I mean, why not? They convinced us to give chocolate to people we love, eat it when we are happy, when we are sad, when only the dog understands us. Don’t feed chocolate to your dog. And we have done all this with a bitter seed that most of us would probably spit out if we tasted it straight from the tree.
I’ve been doing a series about foods that built civilizations. In this episode, we are talking about the potato. It is difficult to imagine that thousands of years ago, people constructed large buildings, managed rivers, built monuments, and created art. We have glimpses of these civilizations through stories, archaeology, and the structures they left behind, but much of their history has been lost. Imagine, we don’t even know where Cleopatra or Alexander the Great are buried, yet we know their stories. As European powers conquered Indigenous peoples, their languages, cultures, and oral traditions were suppressed. When a language disappears, so are the stories preserved within it. Our clues come from archaeology when we uncover a monument, a building, or an ancient settlement. In the Andes, the potatoes they cultivated were not the Russets, Yukon Golds, or fingerlings you find in the store today. Different colors, shapes, and textures. Adapted to survive the elevations, temperatures, and growing conditions. Biodiversity protected their food supply against frost, disease, and changing environmental conditions. If one variety failed, another might survive. The ancient wisdom of diversity that Andean farmers developed over thousands of years was lost when the potato eventually reached Ireland.
In our series about foods that built civilization, we talked a lot about grains, from wheat to corn to rice. Today, we are taking you to the ocean, with the civilizations that salmon built. From California to the interior of Alaska, salmon, a staple, allowed people to settle into villages, develop complex social networks, art, and trade routes. Those trade routes are as large as the ones in the Mediterranean. Some tribes built communal homes and developed complex art and language. Some were Seafaring tribes with canoes up to 60 feet long that traveled across oceans. All because there was a fish that would return in large numbers to streams and rivers, reliably, predictably. So predictable, the people could build their lives around salmon runs. So much so that some built a calendar not only with lunar cycles, but also with the return of the salmon. Civilizations have always gathered around food and water. The Mediterranean connected people who grew wheat and olives, giving people time to make wine, mine copper, build ships, trade with their neighbors, and occasionally go to war with them. Asia had rice and grain near the great river systems. The reliable calories from rice and grains allowed villages to become cities and to travel by water to trade. Today we are going to my home, from the Ventura River in California to my home state of Alaska.
