Every day, over 150,000 people die—from illness, age, accidents, war, and everything in between. But Gordy asks a deceptively simple question: Has there ever been a day when no human died?

To find out, we dive deep into prehistoric population crashes, explore the Toba supervolcano, and run the numbers on what it would take to have a true deathless day in human history.

This episode of Smartest Year Ever blends population science, anthropology, mortality data, and genetics to answer one of the eeriest thought experiments of all time. If it ever happened... you probably didn’t hear about it.
