Years 1–3
Baseline literacy
Vocabulary building, consent-forward data handling lessons, and neutral summaries of public research about sleep timing.
How to read it
Scroll sideways; background tint follows your position
The effect is decorative. It does not read sensor data or store scroll metrics beyond ordinary browser behavior.
Years 4–7
Habit documentation
Participants learn to archive notes without interpreting them as clinical signs. Coaches emphasize referral language.
Years 8–12
Systems thinking
Modules connect transportation, kitchen planning, and desk ergonomics as lifestyle context rather than prescriptions.
Years 13–20
Peer circles
Discussion guides focus on sharing resources and citing limitations. No challenges or competitive framing.
Years 21–30
Archivist mindset
Advanced readers maintain longitudinal journals for personal interest, with explicit reminders that archives are not medical records.
Cadence
Seasonal releases
Quarterly PDFs refresh reading lists. Each issue states its editorial cutoff date so you can judge currency.
