What if aging didn't have to mean an inevitable decline in energy, strength, cognition, and performance? In this episode of The Curious Cardiologist, Dr. Sanjay Bhojraj sits down with Dr. Jeffrey Gladden, an interventional cardiologist who transitioned into functional, integrative, and longevity medicine after experiencing his own health challenges. After approximately 25 years practicing interventional cardiology, Dr. Gladden began experiencing persistent fatigue, weight gain, loss of strength, brain fog, anxiety, and depression. When his initial medical evaluation suggested that his results were normal for his age, he decided to investigate further. That personal journey changed his approach to medicine and led him to explore a more individualized model of health—one that considers multiple biological systems, personal risk factors, physical performance, psychological well-being, and the environments that shape our habits. Together, Sanjay and Dr. Gladden discuss why treating disease is different from optimizing health, why one test cannot tell the whole story, and how emerging technologies could transform the future of personalized longevity care. In this episode, you'll learn about: Dr. Gladden's transition from interventional cardiology to longevity medicineHis personal health journey and the search for answers beyond “normal for your age”Why personalized medicine looks beyond population averagesThe role of genetic differences and individual responses in health decisionsThe relationship between stress, trauma, mental health, and physical healthThe five areas Dr. Gladden uses to organize his approach to longevityWhy physical fitness involves the nervous system, coordination, and balance—not just muscleResilience, robustness, and the idea of becoming stronger after challengesHormesis: the concept of beneficial adaptation to certain forms of stressWhy biological aging is more complex than a single numberHow AI, quantum computing, and digital twins might support personalized health optimizationThe emerging role of technology in understanding individual biologyWhy purpose, relationships, and psychological well-being belong in the longevity conversationThe five areas of Dr. Gladden's longevity framework During the conversation, Dr. Gladden describes five interconnected areas: Life energy: Psychological and spiritual well-being.Longevity: The biological processes associated with aging.Health: Understanding and addressing health issues.Performance: Strength, speed, agility, balance, flexibility, and cardiovascular capacity.Environments: Designing surroundings and routines that make healthy behaviors easier to maintain.The broader goal is to understand the individual more completely instead of relying on a single metric or a one-size-fits-all approach.
