In this "Ask Me Anything" (AMA) episode, Peter answers listener questions across a wide range of topics, focusing on practical decision-making and real-world application. He explores how health priorities and strategies should evolve across different decades of life, which chronic diseases are most challenging to manage and how to think about risk hierarchies, and which emerging interventions—beyond exercise—show the most promise for dementia prevention. Peter also breaks down the utility of wearables and explains how to use and interpret DEXA scans effectively. He discusses the challenges of behavior change and how to make healthy habits stick, along with training strategies for balance, stability, and injury resilience, drawing lessons from his own setbacks. Additional topics include high-protein diets and mTOR, how to weigh mechanisms versus outcomes, how to evaluate diet sodas and non-nutritive sweeteners in context, and a range of listener questions covering health fads, emotional health, and sleep routines.
