Frequently Asked Questions About Dr. Giorgio Longevity vs. Health Span Filter
20 answers covering everything from basics to advanced usage.
// Basics
What does 'Health Span over Lifespan' actually mean in practice?
It means you evaluate every intervention by its impact on healthy, disability-free years first, not on total years alive. Adding five years of chronic illness at the end of life is not a win under this framework. In practice, it redirects goals toward staying functional and active longer, rather than chasing a bigger number on a mortality chart.
What is the oxidative stress 'rust model' of aging?
Cells constantly produce energy, and that process leaves behind a byproduct called oxidative stress — like rust accumulating inside your cells. It's the predominant theory of why cells age and deteriorate. Any credible anti-aging intervention must address this mechanism or a proven downstream pathway to be taken seriously.
What is cellular reprogramming and why does it matter?
Cellular reprogramming is the frontier process of taking an aging cell and restoring it to the profile it had in youth or embryonic state. It's Nobel Prize-grounded science and underlies the most credible drug research. It matters because it's fundamentally different from adding antioxidants — it targets the aging program itself, not just symptoms.
What are the strongest evidence-based Health Span levers right now?
Regular exercise (the most under-utilized lever), diet quality, sleep, and management of chronic disease risk. These are unglamorous but are the only currently validated Health Span extenders. The framework anchors every evaluation back to these — because for most people, closing the gap on exercise and sleep beats any supplement stack.
// How To
How do I audit my current supplement stack with this filter?
Go supplement by supplement: bucket each, then ask if it has human clinical proof of Health Span benefit. Check whether it addresses oxidative stress or reprogramming, and flag interactions with your medications and any bleeding, GI, or cancer-correlation risks. Anything that fails the Human Proof Standard is 'hopeful, not real' — decide if it's worth the cost and risk.
How do I evaluate an online biological age calculator result?
Treat it as a motivational prompt, not a diagnosis. Online calculators are fun and occasionally surface a lifestyle blind spot, but they aren't clinically accurate. If a calculator says you're eight years 'older,' don't panic — identify the one or two factors it flagged (usually exercise or sleep) and act on those. For accuracy, an epigenetic clock test is far better.
How do I clarify whether I want lifespan or health span?
Ask yourself: 'Am I trying to live longer, live better for longer, or both?' Most people say 'both' but are secretly optimizing for raw years. The framework redirects any lifespan-only framing toward Health Span, because a longer life spent disabled or chronically ill fails the actual goal of feeling good and staying functional.
Can I use this filter without knowing my medications or conditions?
Yes, but the safety audit is weaker. Medications and conditions are optional inputs, but they matter enormously for step 5 — flagging bleeding, GI, and drug-interaction risks. Without them you can still assess evidence and mechanism, but you should treat any 'safe to try' conclusion cautiously and confirm interactions with a pharmacist or physician.
// Troubleshooting
My epigenetic clock test contradicts my online calculator — which do I trust?
Trust the epigenetic clock more, but neither is a clinical decision tool yet. Epigenetic clocks are more accurate than a birth certificate for predicting Lifespan and disease risk, while online calculators are motivational toys. If they disagree, don't overreact to either — use both as prompts to double down on exercise, sleep, and diet.
A biohacker claims he reversed his biological age by 10 years — is that real?
Almost certainly not proven. Claims of reversing biological age via supplements like NMN fail the Human Proof Standard, since the evidence is mostly in mice. The 'reversal' is often measured on tools that aren't clinically validated. Don't spend $800/month chasing an anecdote — that money buys far more Health Span invested in a gym membership and better sleep.
I'm on blood thinners — which longevity supplements should I be cautious about?
Be very cautious with any antioxidant or nutraceutical, since several can interfere with bleeding and interact with anticoagulants. This framework's step 5 explicitly checks whether an intervention affects bleeding, causes GI effects, or renders other medications ineffective. Never add a supplement stack on blood thinners without clearing it with your prescribing physician first.
Why do so many longevity supplements seem promising but fail this filter?
Because most supplement marketing relies on mechanism plausibility and mouse studies, not human clinical trials. A sound antioxidant mechanism looks convincing on paper, but the execution in supplement form hasn't been validated in humans. The filter doesn't dismiss the mechanism — it just refuses to overstate the evidence until human proof exists.
// Comparisons
How does this filter compare to trusting the $2 trillion longevity industry?
The industry's size reflects consumer demand and hope, not scientific validation. This filter treats market popularity as irrelevant to proof — it demands human clinical evidence regardless of how heavily something is marketed. Where the industry sells expensive unproven stacks, the filter routes you to cheap, boring, validated levers like exercise and sleep.
How does NMN compare to Metformin under this framework?
NMN is a supplement studied mostly in mice with no established human proof of aging reversal — it's 'hopeful, not real.' Metformin is a pharmaceutical with an established human safety profile and active human trials for aging pathways — it's real-science category. Same goal, very different evidence levels. The framework treats them completely differently.
How does an epigenetic clock compare to an online age calculator?
An epigenetic clock is a blood-based test ($200–$1,000+) that examines DNA fragments and is more accurate than a birth certificate for predicting Lifespan and illness. An online calculator is a free self-assessment that isn't clinically accurate. The clock is a real measurement tool (still maturing); the calculator is a motivational prompt.
How does this framework differ from generic 'eat healthy and exercise' advice?
It reaches the same conclusion but arms you to evaluate everything in between. Generic advice can't tell you whether NMN, Rapamycin, or an epigenetic clock is worth it. This filter gives you a repeatable process — categorize, apply Human Proof Standard, audit mechanism, flag risks, deliver a hype-vs-real verdict — before defaulting to the validated basics.
// Advanced
When are cellular reprogramming drugs actually going to be available?
Roughly a decade away from routine human use, according to this framework. The science is real and Nobel Prize-grounded, but routine clinical application isn't here yet. Be skeptical of anyone claiming reversal drugs are available now — the current real-science candidates are Metformin and Rapamycin, still in trials, plus improving epigenetic clocks.
Why can activating healthy cells also be dangerous?
Because an intervention that makes healthy cells more active may also make unhealthy cells more active. This is a critical safety flag: two antioxidant supplements have shown possible correlations with breast and prostate cancer in some studies. Anything that broadly stimulates cellular activity carries this theoretical risk and should be evaluated accordingly.
Should I take Rapamycin for longevity?
Rapamycin is one of the two leading anti-aging pharmaceutical candidates under extensive study, but it's an immunosuppressant used in transplant patients — not a proven or approved anti-aging drug. It sits in the real-science category as a serious contender, but it carries meaningful risks and requires physician supervision. Don't self-experiment with it.
How should I weigh mechanism plausibility versus human evidence?
Human evidence wins. A sound mechanism — like antioxidation addressing oxidative stress — earns an intervention 'hopeful' status but never 'real' status. The framework deliberately separates the two: don't dismiss a plausible mechanism entirely, but don't let it substitute for the Human Proof Standard. Overstating mechanism as proof is the core error of supplement marketing.
