Every so often, a study comes along that challenges the operating assumptions underneath how we think about health.  Not with drama, or with sweeping claims, but with results that feel just a little out of step with the story we’ve been telling. The dominant narrative has been simple:  protect the body, support it, reduce stress wherever possible.  And certainly, there is truth in that.  But biology has always been more nuanced than our narratives.  Because alongside the harms of excessive stress, there exists another, less appreciated truth, that the right kind of stress, in the right dose, doesn’t damage the system, it sharpens it. A recent study in Aging Cell, titled “Periodic Therapeutic Phlebotomy Mitigates Systemic Aging Phenotypes by Promoting Bone Marrow Function“,  explored this idea in a…

What it Really Means to Stay Active for Life There’s a quiet revolution happening in longevity science, and it doesn’t come from a pill bottle, a peptide vial, or some gleaming machine humming in a high-end clinic.  It comes from something much older than all of that – older than medicine itself.  It comes from staying connected, staying engaged, and simply staying in motion. I’m watching it unfold in real time.  Not in a lab or a lecture.  But on cobblestone streets in Spain and Portugal, and in the mountain air outside Marrakesh.  And at the center of it are two people in their 80s, my parents, who have absolutely no interest in slowing down. They are not “doing well for their age.”  They are doing well, period.…

From renewed FDA scrutiny to sharp criticism from segments of organized medicine, and even debates spilling into mainstream media, compounded medications have become the focus of a growing national conversation.  At first glance, the issue is framed as one of safety.  But as with many things in medicine, the reality is more nuanced.  And now, with Colorado Senate Bill 26-066, that nuance is at risk of being lost in a wave of well-intentioned but potentially harmful regulation. This moment deserves careful attention, not just from physicians and pharmacists, but from patients whose care may be directly affected. What Compounding Really Is Compounded medications are not experimental or fringe.  They are customized prescriptions, created by licensed pharmacists based on a physician’s order to meet the specific needs of an…

Where the Story Begins If you want to understand the Mediterranean diet, you don’t begin in a laboratory or a clinic or even with a stack of nutritional studies.  You begin on a narrow stone street somewhere in Spain or Portugal, where the morning air carries the smell of strong coffee, warm bread, olive oil, and the faint salt of the sea. Right now my wife and I are traveling through the Iberian Peninsula, with my parents, and my sister and her husband, wandering through Madrid, crossing the old bridges of Porto over the Douro River, and sitting at small outdoor cafés where life seems to unfold at a pace that feels both ancient and strangely healthy.  We’ve walked miles and miles over cobblestones, up steep hills, through…

How to Turn 101 and Still Know Where You Left Your Glasses Some people collect stamps.  Some people collect regrets.  And some people, apparently, collect proteins that refuse to age. In 2026, a group of Swiss researchers did something wonderfully inconvenient: they drew blood from centenarians – actual, verified, triple-digit humans – and asked a molecular question that modern medicine has been politely avoiding.  “What exactly are you people doing differently?” They didn’t find anti-aging magic dust.  They didn’t find a secret Alpine herb.  They found something far more subversive.  They found that certain proteins in centenarians behave as though the body forgot to read the expiration date. Not younger-looking.  Not Botoxed.  Biochemically younger.  Let’s talk about what that means. Aging Is Supposed to Be a Slow Systems…

Cultivating the Biology of Cancer Remission There is a new kind of limbo in oncology.  It did not exist twenty years ago.  It arrived with molecular surveillance.  It lives in the space between what we can see and what we can measure. The cancer is in “remission”.  Then a tumor-informed circulating tumor DNA test turns positive.  Or a circulating tumor cell test remains positive.  The PET scan, however, is pristine.  You’re tumor free, but not cancer free.  The radiologist shrugs politely.  The oncologist says, “We’ll repeat imaging in a few months.” And so the patient goes home.  And waits. This moment is medically rational and psychologically devastating.  We can’t see a tumor.  We can’t target what we can’t see.  But biologically, this is not neutral territory.  This is…

Particles, Payloads, and Why Counting Trucks Matters More Than We Thought For most of modern medicine, cholesterol has been treated like a suspicious substance sneaking through the bloodstream – greasy, malevolent, and best arrested on sight.  This is unfortunate, because cholesterol is not only innocent, it’s indispensable.  It’s so important our body recycles it.  Without it, you don’t get hormones, cell membranes, bile acids, or a functioning brain.  You also don’t get very far in evolutionary history. The real problem, as it turns out, was never cholesterol.  The problem was that we were looking at the cargo instead of the traffic.  The cholesterol hypothesis turns out to be more myth than medicine. Blood is a lipid highway.  Lipoproteins are vehicles.  Cholesterol and triglycerides are cargo.  Cardiovascular disease, when…

A Slightly Irreverent Field Guide to Cellular Energy If you zoomed in far enough, past skin, past muscle, past internal organs and all the way into your cells, you’d find a city of tiny power plants humming along in the dark.  These are mitochondria.  They do not care about your emails.  They do not care about your cholesterol score.  They only care about one thing:  ATP ATP (adenosine triphosphate) is the spendable currency of biology.  It pays for muscle contraction, neurotransmitters, immune surveillance, hormone synthesis, and the quiet dignity of staying alive.  When ATP flows, you feel capable.  When it falters, you feel like someone unplugged your soul. Let’s step inside the machine. The Engine Room Where Mitochondria Make Energy Mitochondria sit inside your cells like coiled red…

French fries have an image problem.  They sit in the cultural dock like repeat offenders – greasy, addictive, and somehow responsible for everything from metabolic syndrome to the collapse of Western civilization.  The potato, the poor innocent tuber, has been convicted without a fair trial. But here’s the inconvenient truth:  it’s not the potato.  It’s the oil.  And more specifically, it’s the type of oil and what we’ve done to the oil.  If you could interview a French fry, it would probably say, “I was fine until the oil went bad.” Once upon a time, fries were not the villain.  There was a time, not that long ago, when people ate fried potatoes regularly and didn’t need a recovery day afterward.  Belgian fries cooked in beef tallow.  American…

Mitochondria, Meaning, and the Long Goodbye of Viral Illness Long after the fever breaks and the test turns negative, many people discover that something essential never came back online.  The body is present.  The labs look acceptable.  The doctors are polite.  And yet energy – real energy, the kind that lets you think clearly, walk uphill, or feel joy without planning it – remains stubbornly unavailable. This is the strange aftermath of post-viral illness, now most visible under the banner of Long COVID but familiar to clinicians who have followed patients through Epstein–Barr, Lyme, influenza, and other infections that refuse to leave quietly.  These syndromes are not defined by a single symptom but by a shared absence of vitality without explanation. A growing body of research now suggests…

Modern medicine is spectacular at emergencies.  It can replace hips, restart hearts, and peer into the body with machines that would have looked like witchcraft a century ago.  Yet it remains strangely awkward around one of the most ancient, effective, and low-tech healing tools humans have ever known:  touch. Massage therapy, despite being practiced in nearly every culture for thousands of years, is still treated as indulgence – something you do on vacation, or after you’ve “earned it.”  This is a mistake.  Regular massage is not a spa accessory.  It is a neurological intervention, an immune modulator, a circulatory assist, and a stress-biology reset button – all delivered through the skin, the largest sensory organ we have. If the body were a novel, massage would be the editor…

There was a time – recent enough that your grandparents could still complain about it – when Americans spent a ridiculous amount of money on food.  Not truffle oil money.  Not chia-seed pudding money.  Just… food.  Real food.  Flour, eggs, vegetables that looked like vegetables, meat that once had opinions. Back then, food took up nearly a quarter of the household budget.  A quarter. Imagine that now.  You’d have to refinance your house just to buy an apple that hadn’t been in a factory relationship with corn syrup. Healthcare, on the other hand, was modest.  A doctor’s visit didn’t require a second opinion from your accountant.  Insurance was something you bought for your car, not a philosophy you argued about at dinner parties. Then something very American happened. …

Why the New Guidelines Caused Confusion Every few years, new dietary guidelines are released and a familiar wave of anxiety follows. This time, the emphasis on protein has left many people wondering whether everything they’ve learned about healthy eating has suddenly been overturned. Questions come quickly: Does this mean I should eat more meat? Is plant-based eating outdated? Have vegetables been quietly demoted? The short answer is no. The longer, more accurate answer is that the guidelines haven’t changed direction nearly as much as the headlines suggest. What the Guidelines Are Actually Saying When read carefully, the guidelines continue to emphasize whole, minimally processed foods as the foundation of good health. They encourage adequate protein intake, especially for aging adults, but they do not prescribe meat as the…

What That Little Red Light Actually Reveals About Your Sleep Nocturnal oximetry is a simple overnight test that continuously measures oxygen saturation (SpO₂) and pulse rate while you sleep. It is not a full sleep study, but it is an effective screening tool. When interpreted properly, it can reveal patterns suggestive of sleep apnea, hypoventilation, or other forms of nighttime oxygen instability. Baseline Oxygen Saturation In healthy adults at sea level, normal sleeping oxygen saturation is typically between 95 and 100 percent. It is common for saturation to drift slightly lower during REM sleep, and brief dips to 92 or 93 percent may occur even in healthy individuals. Concern begins when oxygen levels fall below 90 percent, particularly if the drops are sustained or repetitive. Oxygen levels below…

“Before you heal someone, ask him if he’s willing to give up the things that made him sick.” —Hippocrates (Who, it should be noted, did not own a microwave.) The Long, Unsexy Truth About Health Health does not arrive on a white horse.  It does not burst through the door yelling, “Surprise! You’re cured!”  And it definitely does not come with free shipping. There is no secret handshake. No magic smoothie. No supplement discovered in the Peruvian rainforest that absolves you of yesterday’s decisions. Health, like trust or wisdom or a decent sourdough starter, is built slowly – through repetition, patience, and the occasional failure followed by a better choice the next day. Great health is not achieved by heroics.  It’s achieved by boringly good decisions made over…

If laughter is the best medicine, then I’d like to think music is a close second.  I discovered around the age of 18 that I have an ear for playing music, which is a blessing and a curse.  I’m confessing that my love for music borders on problematic.  Most days if I’m running behind I can blame it on the irresistible gravitational pull of that glorious black and white keyed beast that lives in our living room.  Other times, the guitar is impugned.  If the jazz bars would have me and I could pay the bills, I’m afraid medicine might become my hobby. Listening to music is equally appealing.  Mozart helps the infant brain grow and the college student score higher in math.  Whether it’s Beatles or Stones,…
