Blagosklonny of Roswell Park Cancer Institute.\u003c\/p\u003e\n\u003cp\u003eThe author's approach is grounded in the \u003cstrong\u003ehyperfunction theory of aging\u003c\/strong\u003e, which proposes that aging is not simply wear-and-tear damage, but rather a continuation of growth and development gone awry. In this view, growth-promoting pathways in the body—especially the \u003cstrong\u003emTOR pathway\u003c\/strong\u003e (a cellular \"master switch\" that regulates growth and metabolism)—remain inappropriately active later in life, driving age-related diseases like cancer, heart disease, and Alzheimer's.\u003c\/p\u003e\n\u003cp\u003eIf that sounds technical, here's the takeaway: the author believes we already have drugs that can slow this process. The key question is which drugs actually work—and the evidence, he argues, points strongly to one clear champion.\u003c\/p\u003e\n\n\u003ch2 id=\"antioxidants\"\u003eWhy Antioxidants Failed to Extend Life\u003c\/h2\u003e\n\u003cp\u003eYou've probably heard that antioxidants—like vitamins C and E, beta-carotene, and selenium—can fight aging by neutralizing harmful molecules called \u003cstrong\u003ereactive oxygen species (ROS)\u003c\/strong\u003e. The logic seems simple: if ROS cause molecular damage, and damage causes aging, then antioxidants should slow aging.\u003c\/p\u003e\n\u003cp\u003eBut the evidence tells a very different story. The author points out that while knocking out antioxidant enzymes in animals can shorten lifespan, giving extra antioxidants does \u003cstrong\u003enot\u003c\/strong\u003e extend it. Even worse:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eClinical trials of antioxidants in humans have actually shown \u003cstrong\u003eincreased mortality\u003c\/strong\u003e\n\u003c\/li\u003e\n  \u003cli\u003eSome trials were \u003cstrong\u003eterminated early\u003c\/strong\u003e because of increased cancer incidence\u003c\/li\u003e\n  \u003cli\u003eAntioxidants were shown to \u003cstrong\u003epromote cancer in mice\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWhy? According to the author, ROS do cause molecular damage, but no organism lives long enough to die from that damage alone. The hyperfunctional, mTOR-driven aging process \"terminates life first.\" In other words, you cannot extend life by fixing a problem that isn't the one actually killing you. \"We cannot extend life by targeting a non-life-limiting process,\" he writes.\u003c\/p\u003e\n\n\u003ch2 id=\"goal\"\u003eThe Real Goal of Geroscience\u003c\/h2\u003e\n\u003cp\u003eThe \u003cstrong\u003egeroscience hypothesis\u003c\/strong\u003e holds that aging itself is the root cause of most chronic diseases, so by slowing aging, you can simultaneously prevent or delay many diseases. The author embraces this concept but extends it: the ultimate goal of geroscience is \u003cstrong\u003elife extension achieved through health extension\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eThis is an important distinction. Standard medical interventions can extend life without improving health—for example, putting a comatose patient on a ventilator. But anti-aging interventions are different: they extend life by slowing the aging process and thereby delaying all age-related diseases at once.\u003c\/p\u003e\n\n\u003ch2 id=\"healthspan\"\u003eHealthspan vs. Lifespan: What's the Difference?\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eHealthspan\u003c\/strong\u003e is defined as the period of life free of age-related diseases. It's essentially \"disease-free survival.\" And here's where the author takes a strong stance: if a drug genuinely increases healthspan, it \u003cstrong\u003emust\u003c\/strong\u003e also increase lifespan—because animals and humans don't die from good health; they die from diseases. If diseases are delayed, the animal lives longer.\u003c\/p\u003e\n\u003cp\u003eSo how do some studies claim that drugs like resveratrol, senolytics, or NAD boosters improve healthspan without extending lifespan? The author offers several explanations:\u003c\/p\u003e\n\u003col\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThey may not actually improve healthspan at all.\u003c\/strong\u003e Many studies use \"ambiguous or irrelevant markers of health\" that can be associated with either good or bad health depending on the underlying cause.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSome diseases are not deadly.\u003c\/strong\u003e Treating non-fatal conditions can improve quality of life without extending lifespan, and healthspan should not be measured only by such conditions.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSome age-related changes are not life-limiting.\u003c\/strong\u003e For example, accumulation of mitochondrial DNA mutations, telomere shortening, and NAD+ depletion may never reach a lethal threshold during a normal lifetime, because hyperfunctional aging kills the organism first.\u003c\/li\u003e\n\u003c\/ol\u003e\n\n\u003cp\u003eThis last point matters. These \"non-limiting\" deteriorations \u003cem\u003ecan\u003c\/em\u003e become lethal if normal aging is dramatically slowed. So there's an exciting possibility: once a true anti-aging drug like rapamycin decelerates aging, adding a \"healthspan-only\" drug might extend life even further—because the organism may now live long enough for those other deteriorations to become relevant.\u003c\/p\u003e\n\n\u003ch2 id=\"mice-to-humans\"\u003eIf It Doesn't Work in Mice, Why Would It Work in Humans?\u003c\/h2\u003e\n\u003cp\u003eHere's the author's central argument: \u003cstrong\u003eif a drug doesn't extend lifespan in mammals like mice, there's no reason to think it will work in humans.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eConsider calorie restriction (CR), the best-studied longevity intervention. It extends lifespan in mice, rats, and even monkeys. Even then, some gerontologists debate whether it would extend life in humans. But imagine if CR didn't extend lifespan in \u003cem\u003eany\u003c\/em\u003e mammal—would anyone suggest it might \"mysteriously\" work only in humans? Of course not. Yet that's exactly what happens with drugs that fail to extend life in mice but are still promoted for human longevity.\u003c\/p\u003e\n\u003cp\u003eTo reasonably expect a drug to extend human lifespan, it must at minimum extend \u003cstrong\u003emedian and maximum lifespan\u003c\/strong\u003e in genetically heterogeneous mice, multiple strains of mice, and cancer-prone mice.\u003c\/p\u003e\n\n\u003ch2 id=\"resveratrol\"\u003eResveratrol: The Red Wine Compound That Fell Short\u003c\/h2\u003e\n\u003cp\u003eResveratrol—the compound found in red wine and grapes—has been one of the most hyped anti-aging molecules.

The HCD shortened lifespan by increasing early death, and resveratrol prevented that shortening—but it did \u003cstrong\u003enot\u003c\/strong\u003e extend lifespan beyond what a normal standard diet provided.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIn other words, resveratrol may reverse life-shortening caused by a poor diet, but it does not extend normal lifespan. The author notes that this is like giving insulin to animals dying prematurely from type 1 diabetes—it extends their lives, but insulin is not an anti-aging drug. In fact, insulin is \"pro-aging rather than anti-aging.\"\u003c\/p\u003e\n\n\u003ch2 id=\"rapamycin\"\u003eRapamycin: The Standout Drug\u003c\/h2\u003e\n\u003cp\u003eIf there is one clear winner in this review, it's \u003cstrong\u003erapamycin\u003c\/strong\u003e.

Lifespan is how long you live.

Since 2009, multiple studies have shown it extends median and maximum lifespan in both male and female mice, across many strains, and even in some short-lived mice. It extends life whether given early or late, and higher doses produce greater effects. It doubled lifespan in some mice.\u003c\/p\u003e\n\u003ch3\u003eDoes metformin extend lifespan in mice?\u003c\/h3\u003e\n\u003cp\u003eMetformin's effects in mice are mixed and depend on strain, sex, age, and dose. For example, it decreased male lifespan in one study and increased female lifespan in another. It extended lifespan in female SHR mice and in cancer-prone mice. However, in normal mice, results ranged from life extension to life shortening. In humans, it may lower all-cause mortality, but the ideal dose matters.\u003c\/p\u003e\n\u003ch3\u003eDo NAD boosters like NMN and NR extend lifespan?\u003c\/h3\u003e\n\u003cp\u003eNicotinamide riboside (NR) extended mouse lifespan by 4.7%, a result that was only marginally significant.

The article's argument is academic and not mainstream medical advice. Rapamycin can suppress immunity and impair wound healing. Metformin has toxic effects at high doses. Always consult your doctor before using any medication for anti-aging.

These are prescription drugs with real side effects; rapamycin is an immunosuppressant and may increase infection risk, impair wound healing, and alter metabolism. No human longevity data exist for these drugs, and extending mouse findings to humans is controversial. A second opinion can clarify whether your personal health profile makes off-label use advisable or whether safer alternatives, including lifestyle changes, are more appropriate.
