Methodology
Population context, held with humility.
TimeToLive will use public life-table data to create an illustrative range. It will never claim to predict an individual death date.
What the future illustration will do
A future phase will select an authoritative public life table by geography and statistical demographic input, then calculate conditional remaining expectancy for a person who has reached their current age. The central value and uncertainty range will retain the dataset, year, geography, and calculation version.
This is an illustration based on public population data, not an individual prediction.
What changes the estimate
Only population-table inputs will inform the illustration. Water, posture, sleep, sitting, and reminder completions will not be converted into exact lifespan gains or losses.
What Life Credits mean
Life Credits are symbolic motivation. They can grow today's plant and the historical garden; they never add literal time to a population illustration.
