Walkback: A Life Replayed in Reverse
A free, multilingual experience that generates a hypothetical life from demographic and habit inputs, reveals its modeled ending, then lets users rewind it year by year.
- For
- People exploring mortality statistics through interactive scenarios
- Worth noticing
- The page explicitly separates real statistics from invented stories: “The numbers are real. The story isn’t.”
Field notes
The simulator assigns a hypothetical starting life using country, sex, age, and four habits, then presents an estimated lifespan and cause of death before letting the user rewind year by year. Some layers can be changed through probability-based choices; the page says unknown conditions such as hypertension or diabetes may affect the modeled outcome. It cites the UN World Population Prospects 2024 revision and says calculations run in the browser without registration or stored data.
