How to read the library
Different questions need different formats.
Root Notes explores an everyday health question. Healthspan Map puts measurements into context. Longevity Brief examines evidence and its limits.
Field Guides organizes practical learning. Rewrite Program offers reflection and planning exercises. RootBook Letters considers meaning, agency, and the experience of aging.
These are editorial formats. Practical exercises are identified as such and are not presented as clinically validated programs.
