Hiroshi Ouchi was a nuclear worker that got 2x the maximum amount of radiation. His body began to deteriorate and fall apart, his chromosomes completely destroyed. Yet, doctors kept him alive over two months after resuscitating him 3 times after his heart had stopped for almost an hour. The doctors had kept him alive for research even though the pain was beyond extreme and (before he lost the ability to speak) he begged for them to let him die. He suffered a slow and painful death.
