When will you die if you are biologically immortal

This study examines how long a biologically non-senescent human might live if ageing were eliminated but death from external causes remained possible. Using a constant-hazard survival model and contemporary mortality data from injuries, violence, conflict, and catastrophe, we estimate that under present-day conditions average life expectancy would still be finite—roughly 1,000 to 2,000 years, depending on the dataset and assumptions used. Scenario analysis shows that outcomes vary dramatically with environment: safer, technologically advanced societies could extend expected lifespan to many thousands or even tens of thousands of years, while war, collapse, or frontier conditions could reduce it to mere decades or centuries. The central conclusion is simple: defeating ageing would not abolish death; it would shift the main limit on lifespan from biology to external risk.
