He explores how to build and interpret a meaningful family health history, how individual risk tolerance influences decisions around testing and treatment, and why heart disease remains poorly prevented despite available tools. He also examines whether it's possible to carry excess body fat while remaining metabolically healthy, outlines the minimum effective dose for strength training for those with limited time, and discusses the habits and interventions most likely to reduce dementia risk. Additional topics include what evidence would need to emerge for him to reconsider his current stance on NAD-boosting supplements, and when hydration and electrolyte strategies are truly beneficial versus unnecessary.
