A man who died and was brought back to life again has revealed what he saw and how he felt during this time - saying there was no 'light at the end of the tunnel'.
Kevin Hill, 55, has calciphylaxis - a serious, uncommon disease in which calcium gathers in small blood vessels of the fat and skin tissues.
He says that his dead skin began eating away at his live skin, resulting in excruciating pain and five pints of blood loss - meaning his heart stopped and doctors had to work to revive him again.
