Japanese human experimentation during WW2: “To determine the treatment of frostbite, prisoners were taken outside in freezing weather and left with exposed arms, periodically drenched with water until frozen solid.

Misfortune can cause a human to become, of no will of theirs, less intelligent, less sane, and less of a good person.

There was a guy, and he had a tapeworm, and the tapeworm had cancer, and the cancer metastatized. And the worm’s cancer cells frolicked all through the guy’s body and took root and grew tumors in his lungs, and the tumors weren’t made of human cells – they were masses of worm flesh. Then he died.
