It starts in your fingers. They grow numb and then your throat tightens and it feels like your vocal chords will snap if you don't scream and your airways clog and you can't breathe and your chest starts to hurt but you can't massage it since your fingers are so numb and the pain becomes so overwhelming that your brain dulls and you can't think, all you can do is feel and feel and feel until you can't feel anything at all and that is how you drown without being in water.
