Based on Joe Biden's current health status, the records of US presidents' longevity, and life expectancy calculations, it is statistically likely that he will still be alive in November 2028. Current life expectancy calculations, based on individual health and lifestyle factors give Joe Biden a 75% chance of living until at least 91 (Vernon, 2023). Furthermore, the average age of dead former US presidents born after 1850, excluding assassinations is 88 years, which supports the likelihood of Biden living beyond the age of 86 (Excel, 1.1).
