Longevity tracking is only useful when it connects interventions to context: labs, sleep, HRV, training, nutrition, side effects, and what actually changed.
| Category | Fields |
|---|---|
| Labs | Date, fasting status, lipid panel, glucose/A1c, liver/kidney markers, hormones if ordered, clinician notes. |
| Recovery | Sleep duration, HRV, resting heart rate, training load, soreness, fatigue. |
| Body composition | Weight trend, waist, strength markers, photos if useful, appetite. |
| Protocol changes | Start/stop dates, injection days, supplement changes, missed days, side effects. |
| Confounders | Travel, illness, alcohol, stress, poor sleep, dietary changes. |
The defensible part of longevity work is measurement discipline. If several variables change at once, the log should say that. If a lab moved after illness, travel, a medication change, and poor sleep, the timeline should preserve that context instead of forcing a clean story.
