We spend too much time being scared of dying in a plane crash or being eaten by a shark, when those things are exceedingly rare. It's prudent to be cautious of traffic accidents, which are a too-common way to die prematurely, but that's a relatively modern problem. Over the course of human history, most deaths come from the natural world. We've been pretty good at battling some of those causes of death, while others are maddeningly constant. Minute Earth details the most common causes of death in human history, one era at a time. Along the way, they tease us about "three other big killers," which are eventually revealed and may or may not surprise you. But they are the things we haven't been able to conquer yet.
