In this special “Ask Me Anything” (AMA) episode, Peter answers a wide range of questions spanning the topics that come up most often in conversations about longevity and health optimization. He discusses which strength and power benchmarks matter most for long-term health, how beginners or time-constrained individuals can start exercising effectively, and why VO₂ max targets reflect planning for the life you ultimately want to live rather than overly aggressive goals. Peter explores the roles of exercise, sleep, and metabolic health in reducing the risk of cognitive decline and dementia, clarifies common misconceptions about insulin resistance and how to detect it earlier, and examines which supplements may be worth considering versus those that are likely noise. He also explains how GLP-1 medications work and where the evidence continues to evolve, how to use wearable health technology productively without increasing anxiety, practical strategies for improving sleep as a foundational pillar of healthspan, and much more.
