Tracking Biological Age with AI and Blood Biomarkers | Tyler Smith

Artificial intelligence is rapidly changing how we understand our health — not just how we feel today, but how fast we’re actually aging. On this episode of Live Long, host Peter Bowes continues his personal experiment with Hundred, the AI-powered longevity platform that combines advanced blood testing, wearable data and personalized insights to track biological age and guide smarter health decisions. After introducing the app in an earlier conversation, Peter reconnects with Hundred’s founder, Tyler Smith, to go deeper into the idea of a “health operating system” — essentially a personal doctor in your pocket. Together they explore how continuous testing and AI analysis could help prevent disease, spot risks earlier, and motivate lasting behavior change — while also addressing the realities of over-testing, false alarms, privacy concerns and health anxiety. Peter also shares the results of his own first round of testing, what surprised him most, and how he’s using the data to shape his approach to longevity and healthy aging. ----- JOIN HUNDRED Optimize your healthspan and potentially lower your biological age.
