What if your doctor could predict what will kill you—before it ever becomes a problem? In this episode of Precision Medicine Made Simple, we dive into the evolving landscape of longevity medicine and health AI with Dr. Hillary Lin, Stanford-trained internist, former oncologist, and co-founder of CareCore—a platform empowering wellness creators and brands to offer doctor-supervised, data-driven care.

Dr. Lin shares her personal journey from frustration with traditional medicine to building one of the most forward-thinking longevity platforms today. She discusses how we can sift through misinformation, integrate wearables, genetics, and proteomics, and balance the promise of AI with the human art of medicine.

If you're interested in the intersection of tech, behavior change, and personalized healthcare—or you're a clinician navigating this fast-changing world—this episode is a must-listen.
