He can't breathe, and the hand around his throat isn't letting up any time soon.
He thrashes about and lashes out with his feet, but it's futile. His assailant continues to choke him, strangling him slowly. The hand on his throat is too strong. His eyes begin to water as he realizes he's never going to grow old with his wife, or see his kids get married.
His body goes limp and he stops fighting, yet the hand squeezes on. Finally, he dies, his face purple from exertion and lack of air, and tears rolling down his cheeks. His body is soon to grow cold, and his wife will awake to a bed shared with a corpse. Her scream will wake her kids, who will grow up without a father.
But most of all, the next day;s headlines will read "Frank Iero Chokes Self To Death".
There is something known as alien hand or something like that where your hand is outside your control and may try choking you.
