Episode 73: The Symphony of Aging: Dr. Raghav Sehgal on Epigenetic Clocks & Longevity

In this episode, Dr. Jeremy Koenig sits down with Dr. Raghav Sehgal, a Yale-trained computational biologist and longevity researcher, to uncover the science behind aging, resilience, and the future of preventative medicine. From his unconventional journey starting in electronics engineering in India to pioneering breakthroughs in epigenetic clocks and system-specific biomarkers of aging, Dr. Sehgal reveals how technology, biology, and proactive healthcare intersect to redefine longevity. Together, they explore how aging is not a single timeline but a complex symphony across 11 bodily systems, why resilience is as important as lifespan, and how interventions—from intermittent fasting to personalized medicine—can reshape healthspan. The conversation also dives into the limitations of reactive healthcare, the role of big pharma, and the promise of proactive, precision-based longevity science. Whether you’re a biohacker, physician, or someone curious about living not just longer but better, this episode offers insights into the future of aging research and human flourishing.✨ Key Takeaways:🧬 Aging is not one clock—it’s 11 interconnected systems that can be tuned like instruments. 🩺 Moving from reactive medicine to proactive longevity science is the key to healthier lives. 💊 Epigenetic clocks reveal how interventions like Ozempic and lifestyle changes target specific organ systems. ⚡ Resilience—your body’s ability to bounce back—is a stronger predictor of healthy aging than years alone. 🤝 Social connections and mental health are just as critical as diet, exercise, and sleep for longevity. 🥗 Intermittent fasting, diverse exercise, and preventative care are simple but powerful tools for better healthspan. 🌍 The future of medicine may include longevity clinics, personalized dashboards, and even gamification of aging. LINKS:https://www.drjeremykoenig.com/https://www.instagram.com/drjeremykoenig/https://www.youtube.com/@drjeremykoenigHere's the link for this week's episode: https://drjeremykoenig.substack.com/.
