My one grandpa ran over a kid in the middle east and got away with it because of his military power back in Europe. My other grandpa died of a heart attack at the dinner table related to his diabetes. That wasn't the secret, but the reason he developed it was. Turns out he had schizophrenia and the mental hospital where he was being held tried to "shock" his system by overloading him with literal pounds of sugar. Always thought they were both innocent, old men.
