In this episode of The Science of Age-less Living, Dr. Ethan cuts through the noise around “anti-aging” and peptide culture to lay out what longevity medicine actually is: evidence-based risk management, not influencer-driven optimization. You’ll hear why the biggest threats to lifespan and healthspan are still cardiovascular disease, metabolic dysfunction, neurodegeneration, and cancer—and why no peptide stack can compensate for ignored biomarkers, unchecked ApoB, poor glucose control, or low fitness.

Dr. Ethan breaks longevity into a practical hierarchy: Tier 1 fundamentals (sleep, VO2 max, ApoB control, insulin sensitivity), Tier 2 amplifiers (mitochondrial function, inflammation control, physiologic hormone optimization), and only then Tier 3—targeted peptides used selectively, with clear indications and lab monitoring. He highlights where specific peptides may have legitimate utility in narrow clinical contexts, and calls out the most common “longevity clinic” hype—from exosomes and stem-cell claims to reckless GLP-1 use in already-lean patients.

The takeaway is simple: peptides can be useful tools, but they’re not the foundation. Real longevity comes from mastering the boring, proven levers—and using advanced interventions only when the data says you actually need them.

In this episode of The Science of Age-less Living, Dr. Ethan argues that aging is not primarily about accumulated damage (oxidative stress, inflammation, telomere shortening), but a loss of timing and synchronization in the body’s biological clocks.

The master clock (SCN in the brain) and peripheral clocks in organs coordinate hormones, gene expression, metabolism, repair, and immunity in precise rhythms—strong and harmonious in youth, but increasingly damped and desynchronized with age. This breakdown causes inefficient repair, unchecked inflammation, and rapid functional decline, explaining why organs age at different rates and why short-term sleep loss accelerates aging markers faster than expected.

Sleep is highlighted as the key synchronizer (via melatonin, growth hormone pulses, etc.), while continuous, non-rhythmic interventions (daily NAD+ boosters, peptides, supplements) often backfire by flattening natural oscillations and worsening discord.

The solution: prioritize rhythm restoration through optimized sleep, light-dark alignment, and pulsed, cyclical, personalized protocols that respect the body’s innate timing rather than brute-force constant stimulation. By re-synchronizing the “orchestra,” vitality and healthy lifespan can be meaningfully extended.

In this episode of The Science of Ageless Living, Dr. Ethan Hausman-Marquis unpacks autoimmune fatigue in conditions like MS, lupus, and rheumatoid arthritis—and why it’s so often misunderstood. Fatigue isn’t laziness or deconditioning; it’s a biological safety response to chronic inflammation.

He explains how inflammation disrupts neurotransmitters, autonomic balance, and oxidative stress, with mitochondria at the center. In autoimmune disease, mitochondria intentionally downshift energy production to protect cells from damage—an intelligent adaptation, not failure.

A key takeaway: more energy isn’t always better. Aggressive interventions like NAD+ or stimulants can override the body’s protective signals, increasing the risk of flares. True repair happens in parasympathetic, rest-and-digest states.

The episode outlines a smarter strategy built on timing, low-and-slow dosing, and restraint—prioritizing nutrition, sleep, gentle movement, and stress regulation before metabolic “boosts.” Fatigue is reframed as a signal to respect biology, not fight it.
