Derek Nance, a 30-year-old Kentucky man, has been eating only meat he has slaughtered—including rotten meat—for the past five years. After getting physical ill five years ago, Nance decided to change his eating habits, and ultimately took it to an extreme. He claims to have gotten stronger and "more physically robust" since eating this way. And when he's done with a meal, "I wash it all down with a good cup of blood," he said.
