Episode Summary

In this episode of The Longevity Lab, we explore the fascinating convergence of billion-dollar medical breakthroughs and the raw power of human sweat. We dive into the world of Natural Killer (NK) cells—the "special forces" of your immune system—and how they serve as the ultimate bouncers of your biological city.

We start with the revolutionary work of Dr. Patrick Soon-Shiong, the billionaire surgeon behind the "Cancer BioShield." Learn how his "Triangle Offense" uses low-dose chemotherapy and the FDA-approved drug Anktiva to wake up dormant NK cells and hunt down "invisible" tumors.

Then, we pivot to the track. Discover how chasing an elite VO2 Max isn't just about athletic performance—it’s about biological de-aging. We break down the science of how high-intensity exercise mimics cutting-edge immunotherapy by flooding your system with adrenaline and IL-6, mobilizing a "search party" of NK cells that can increase by up to 500% in a single workout.

Whether you are interested in the future of cancer treatment or looking to build a "BioShield" through your own fitness, this episode reveals how to empower your body's natural assassins.

• The "Missing-Self" Mystery: Why NK cells can see the cancer cells that hide from the rest of your immune system.

• The Soon-Shiong Protocol: A deep dive into Anktiva (IL-15) and the future of "off-the-shelf" immune reinforcements.

• The VO2 Max Advantage: Why moving from average fitness to the top 25% provides the biggest "longevity bang for your buck."

• Exercise as Medicine: The specific role of Epinephrine and Interleukin-6 in guiding your immune cells to the front lines.

• The 1% Goal: What happens to the immune system of a 60-year-old with the fitness of a 20-year-old.

• [00:00] Introduction: The primitive warriors living inside you.

• [05:30] Dr. Patrick Soon-Shiong and the "Cancer BioShield."

• [12:45] Natural Killer Cells 101: Perforins, Granzymes, and the "Kiss of Death."

• [22:15] The Proof: From the "Missing-Self" hypothesis to real-time imaging of cell lysis.

• [30:00] VO2 Max: The gold standard for more than just your heart.

• [38:20] Building your own BioShield: Incremental gains and elite protection.

• Dr. Patrick Soon-Shiong: Inventor of Abraxane and architect of the "Triangle Offense" against cancer.

• The Pioneers: The story of Rolf Kiessling, Ronald Herberman, and Klas Kärre.

• Anktiva (N-803): The IL-15 superagonist currently changing the landscape of immunotherapy.

"Your pursuit of an elite VO2 Max is a natural biological mimic of the most advanced cancer protocols on earth."

The Longevity Builder Health Lab Software — Why It Had To Exist

Subtitle: From Barry Irvin’s Diagnosis to Duncan Armstrong’s Heart Attack—The Story Behind the World’s First Unified Longevity Operating System.

In this flagship bonus episode, Shane Stubbs pulls back the curtain on the "why" behind the Longevity Builder Health Lab. This isn't just about another health app; it’s about a radical shift from fragmented health data to a unified, life-saving system.

Shane shares two deeply personal encounters with Australian icons—Bega Cheese Chairman Barry Irvin and Olympic Gold Medalist Duncan Armstrong—that revealed a terrifying truth: even the most successful and "fit" among us are often flying blind when it comes to clinical risk. Shane breaks down his own biomarker transformation, his journey to a 52 ml/kg/min VO₂ Max, and why he spent years building the blueprint that these men didn't have before their catastrophic health events.

• The "Four Days" That Changed Everything: The chilling conversation with Barry Irvin following his Stage 4 cancer diagnosis and the realization that high-level success does not equal high-level health literacy.

• The Myth of the "Fit" Athlete: Why Olympic champion Duncan Armstrong suffered a heart attack at 52 despite his elite background, and his honest admission about understanding clinical risk.

• The "Thousand Islands" Problem: Why having 15 different apps for sleep, steps, and biomarkers is failing us. Shane explains how fragmentation hides the true picture of your health.

• Shane’s Personal Lab Results: A transparent look at Shane’s transformation:

  • Weight: 124 kg ➡️ Transformed.

  • VO₂ Max: 33 ml/kg/min ➡️ 52 ml/kg/min (targeting 60 by age 60).

  • Triglycerides: 1.0 ➡️ 0.7.

  • LDL: 3.4 ➡️ 1.7 (and improving).

• The Four Pillars of the Health Lab:

  • Oxygen Efficiency App: Driving mitochondrial biogenesis and endothelial repair.

  • Activity Quotient (AQ): Moving beyond steps to measure real molecular adaptation.

  • Marginal Decade Blueprint: Mapping your training today to the physical independence you want at age 90.

  • Biomarker Lab: Turning static PDF blood results into an interactive, educational roadmap.

"Health is not a mystery. Longevity isn’t a guess. But the world treats it like one because we’ve handed people fragments instead of the full picture." — Shane Stubbs

"Barry Irvin didn’t get a warning. He got four days that changed everything. Most people never see it coming. But you can." — Shane Stubbs

Don't wait for your "four days." The Longevity Builder Health Lab was created to give you the clarity and the system that Barry and Duncan were missing.

• JOIN THE WAITLIST: The Health Lab and the new Longevity Builder Hardcover Book launch on Shane’s 60th birthday—April 20, 2026.

• SECURE YOUR SPOT: Be the first to access the world's first unified longevity system.

Episode Summary

For decades, the standard medical advice for cancer patients was simple: "Rest. Take it easy. Avoid exertion." Today’s guest has spent her career proving that advice is not just outdated—it is dangerous.

In this episode, Shane Stubbs sits down with Dr. Kathryn Schmitz, the world’s leading authority in Exercise Oncology. Dr. Schmitz is the scientist who literally wrote the book on moving through cancer. She spearheaded the "Exercise is Medicine" initiative and has led over $30 million in research funding to prove that exercise changes the biology of cancer.

We dive deep into why building a resilient body is your best defense, the specific "Move, Lift, Eat, Sleep, Log" framework, and how resistance training impacts survivorship.

PLUS: Stay tuned until the very end for a "Science Spotlight" Bonus Segment. Shane breaks down new research highlighted by Dr. Rhonda Patrick on "Shear Stress"—explaining the physics of how vigorous exercise can mechanically destroy circulating tumor cells and reverse heart aging by 20 years.

• The Paradigm Shift: Why the old advice to "rest" during cancer treatment is being replaced by a prescription for movement.

• The Science: Dr. Schmitz’s $30M+ research journey and her role in writing the ACSM guidelines for cancer survivors.

• The Protocol: The "Move, Lift, Eat, Sleep, Log" framework for building a body that can withstand the "Big Four" (Cancer, Heart Disease, Metabolic Dysfunction, Neurodegeneration).

• Exercise as Medicine: How specific doses of activity can alleviate symptoms, improve chemotherapy tolerance, and boost survival rates.

• BONUS Segment: The physics of Shear Stress. We discuss Dr. Rhonda Patrick’s breakdown of how high-intensity blood flow can kill Circulating Tumor Cells (CTCs) and scrub your arteries.

Dr. Kathryn Schmitz is a Distinguished Professor of Public Health Sciences and a Professor of Physical Medicine and Rehabilitation. A trailblazer in the field of Exercise Oncology, she served as the President of the American College of Sports Medicine (ACSM) and founded the Moving Through Cancer initiative.

With a PhD in Exercise Physiology, an MPH in Epidemiology, and over 300 peer-reviewed scientific papers, Dr. Schmitz is the foremost voice on the intersection of movement and malignancy. She is the author of the book Moving Through Cancer.
