What if the same symptoms we see in combat veterans — the broken sleep, the irritability, the brain fog — were already quietly spreading through the healthiest, highest-performing people you know?

In this episode of Health Longevity Secrets, Robert Lufkin MD sits down with Neil Markey — a former US Army Special Operations captain from the 75th Ranger Regiment turned McKinsey consultant, now the co-founder and CEO of Beckley Retreats and a Harvard Chan School student researching psychedelic-assisted integrated health. Neil walks us through his own journey out of post-combat trauma, the neuroscience of why psilocybin opens a rare window of neuroplasticity in the adult brain, and why he believes this work belongs upstream as preventative medicine for the well.

Five longevity beliefs that millions have followed for decades have just been overturned by the latest research. Some of these will surprise you.

In this explainer, Robert Lufkin MD walks through five of the most widely believed longevity myths — and what the most recent science actually says about each one. From genetics and middle age to antioxidants, alcohol, and caloric restriction, the evidence has shifted dramatically.

CHAPTERS:
00:00 — Introduction
00:32 — Myth 1: Your Genes Determine How Long You Live
01:51 — Myth 2: It's Too Late to Change After Middle Age
03:24 — Myth 3: Antioxidant Supplements Prevent Disease
05:22 — Myth 4: Moderate Alcohol Is Good for You
07:04 — Myth 5: Caloric Restriction Is King
08:50 — The Real Framework: Quality Beats Quantity
09:18 — Final Takeaway

KEY TAKEAWAYS:
• Genetics accounts for at most 25–50% of how long you live
• Quitting smoking before 40 eliminates ~90% of excess mortality risk
• Antioxidant supplements have no benefit and may increase mortality
• The protective J-curve for moderate alcohol disappears once you correct for the "sick quitter" effect
• Caloric restriction's primate magic was rescuing animals from a high-sugar control diet
• Diet quality matters more than diet quantity

What if the most dangerous metabolic inflection point in a woman's entire life is the one we've been taught to simply endure?

In this episode of Health Longevity Secrets, Robert Lufkin MD sits down with Dr. Mayoni Gooneratne — a London-trained former NHS colorectal and pelvic floor surgeon, now the founder of Human Health and vice-chair of the British College of Functional Medicine. Dr. Mayoni walks us through why she walked away from the operating theater and how perimenopause — not menopause — is the real window where metabolic disease, cognitive decline, and cardiovascular risk are either quietly programmed in or actively reversed.

CHAPTERS:
00:00 — Introduction

KEY TAKEAWAYS:
• Perimenopause — not menopause — is the real metabolic inflection point for women
• Loss of estrogen can trigger type 2 diabetes and cardiovascular disease within months
• Chronic high-cortisol lives prime the perimenopause crash
• "Normal" vitamin D isn't optimal vitamin D — aim for ~100
• Nutritional ketosis works as a 16-week reset, not a permanent lifestyle

What if aging isn't a hundred separate problems but a single one — an energy crisis inside the tiny power plants of every cell? At 91, Dr. John G. Cramer is betting his own body on the answer.

In this episode of Health Longevity Secrets, Robert Lufkin MD sits down with Dr. John G. Cramer — Emeritus Professor of Physics at the University of Washington and author of "How to Live Much Longer" — the oldest human on Earth to receive an experimental mitochondrial transplant. They unpack a unifying theory of aging built around damaged mitochondrial DNA, why replication errors (not just free radicals) drive most of the damage, and what it felt like to receive escalating doses of "Mitlets" — liposomes carrying fresh mitochondria harvested from young blood platelets — at a Texas right-to-try clinic.

Your doctor orders a lipid panel every year — but 3 cheap blood tests predict heart disease, diabetes, and even dementia far better than cholesterol, and most doctors never order them.

In this episode, Robert Lufkin MD walks through fasting insulin + HOMA-IR, homocysteine, and high-sensitivity CRP — three tests that together cost about $60, take one blood draw, and catch the metabolic dysfunction a standard lipid panel systematically misses.

CHAPTERS:

• 00:00 — The 3 Blood Tests Your Doctor Isn't Ordering
• 00:40 — Part 1: Fasting Insulin and HOMA-IR
• 01:15 — How Insulin Resistance Hides for 10–15 Years
• 01:45 — HOMA-IR vs Glucose: What 516,000 People Revealed
• 02:05 — 59% Higher Cardiovascular Risk in the 2023 ATVB Study
• 02:45 — Optimal Fasting Insulin: Why 5–8 Beats the Lab's "25"
• 03:05 — Part 2: Homocysteine and the MTHFR Connection
• 03:35 — How Homocysteine Damages Your Arteries (6 Mechanisms)
• 03:50 — 60% Higher Stroke Risk and 48% Alzheimer's Risk
• 04:35 — The Oxford VITACOG Trial: 53% Less Brain Atrophy
• 05:05 — Part 3: High-Sensitivity CRP and Inflammatory Plaque
• 05:40 — The JUPITER Trial: 44% Drop in Cardiac Events
• 06:15 — UK Biobank: Why hs-CRP Beats LDL Cholesterol
• 06:50 — AHA Risk Categories for hs-CRP Since 2003
• 07:15 — Part 4: The Metabolic Picture (Why Cholesterol Is the Wrong Target)
• 07:50 — 3 Tests, $60, One Blood Draw — The Full Framework

KEY TAKEAWAYS:

• Fasting insulin + HOMA-IR catches insulin resistance a decade before glucose goes abnormal — optimal is below 5–8, not the lab's reference range of 25
• Every 5 µmol/L rise in homocysteine raises coronary artery disease risk 20–30% and stroke risk 60%, independent of cholesterol
• hs-CRP predicted cardiovascular events better than LDL in a 322,000-person UK Biobank analysis — yet fewer than 10% of cardiac panels order it
• Cardiovascular disease, type 2 diabetes, and dementia share the same upstream driver: metabolic dysfunction, not cholesterol
• All three tests together cost roughly $60 and come from a single blood draw

What if the single device you hold closest to your body for 10+ hours a day is quietly rewriting your biology — and your grandchildren's?

In this episode of Health Longevity Secrets, Robert Lufkin MD sits down with Daniel DeBaun — a former Bell Labs and AT&T telecom engineer who helped build the very wireless standards the industry still runs on, then walked away to warn us about them. He is the founder and CEO of DefenderShield and co-author of "Radiation Nation," and he pulls back the curtain on what 4G, 5G and the coming 6G are actually doing to the human body, the gut microbiome, fertility, and the developing child.

CHAPTERS:
00:00 — Introduction
02:18 — Daniel's Bell Labs Origin Story
03:36 — The Laptop Incident That Changed Everything
05:51 — EMF 101: What You Need to Know

37:58 — DefenderShield and How Shielding Works
39:41 — Why Kids Are Most at Risk

KEY TAKEAWAYS:
• Heavy cellphone users (1+ hrs/day for 10+ years) face up to 3× the risk of frontal-lobe cancer
• Non-ionizing EMFs damage cells through calcium-channel disruption, not just heat
• The gut microbiome is directly altered by radio-frequency exposure
• Up to 50% of people now report symptoms of electro-hypersensitivity (headaches, nausea, stress)
• Current FCC safety standards were written in 1990 for a 6-foot male soldier — with the phone held 1 inch from the head
• Simple home changes — wired internet, phone off the body, distance from routers — cut most exposure

STUDIES & SOURCES MENTIONED:

• National Toxicology Program cell phone radiation study (2018) — "clear evidence" of heart tumors and DNA damage in rats
