Death Date 3000 is a retro arcade-styled life expectancy calculator, built by Nick — one person who thought a joke website about dying needed way more effort than it strictly deserved.
What started as a simple "guess your death date" gag turned into a full factor-by-factor breakdown grounded in actual published research on smoking, exercise, alcohol, sleep, and more — because if you're going to build a novelty tool, it might as well be an honest novelty tool.
