Where biomarkers appear In this channel's material, biomarkers show up as one category of self-knowledge worth encoding in Jonny Miller's Codex Vitae — the personal knowledge base he gives an AI so its coaching responses become much more relevant and personalized. His codex lists, among other things, ideal weekly calendar, energetic black holes, reactivity triggers, burnout warning signs, decision-making principles, biomarkers, biometrics, and prior experiment results.[^367224da-ffda-58fc-a5a5-55381e01ef16@0] How it is used Biomarkers are treated as data about yourself that an AI coach can reference.
