The Killing Fields

What is the worst death that you can possibly imagine? It's a hard quesiton. But something you'd never think of:

Literally working yourself to death. You have no food to eat, but are still forced to work in rice fields the whole time. If you mess anything up, you are dead. They even suffocated people that slipped up with plastic bags. The killing fields were ruthless. If you confessed to anything the Khmer Rouge didn't like, they would kill you. Confessions were even made that were untrue just to escape the retched place.There were only 2 options to escape:

Death or running. And they both resulted about the same.
