What’s actually breaking down inside your body as you age? In this episode of The Functional Code, Dr. Jace and Dr. Addie explore the biology of aging from the inside out — DNA damage, epigenetics, mitochondrial function, autophagy, senolytics, NAD+, stem cells, peptides, air quality, and the lifestyle factors that shape how your body repairs itself over time. Every cell in your body experiences thousands of DNA lesions per day, and your body repairs almost all of them. But the problem may not be the damage itself — it may be the cost of constantly repairing that damage. The doctors break down aging through powerful metaphors, including the “repair crew” analogy and the orchestra analogy, where your DNA is the sheet music and your epigenome is the conductor. As the conductor loses precision, the same genetic code can start producing different outcomes: wrinkles, arrhythmias, immune dysfunction, cognitive decline, and other signs of aging. They also explore the future of longevity science and ask a deeper question: If we can slow or reverse aging, should we? This episode covers: DNA damage and cellular repairEpigenetics and gene expressionWhy aging may be the cost of repairUV radiation, stress, alcohol, tobacco, and processed foodsMitochondrial dysfunction and cellular declineAutophagy, fasting, and exerciseNAD+, sirtuins, senolytics, and peptidesStem cells and regenerative medicineAir quality and environmental agingAI, culture, mental health, and the future of human healthWhy exercise, sleep, and nutrition still sit at the top of the longevity pyramid Key takeaway:The future of anti-aging medicine may be powerful, but the highest-value tools are still the fundamentals: exercise, sleep, nutrition, clean air, stress regulation, and doing hard things consistently.
