The pain of losing something so precious that you did not think you could live without it. Oxygen. The ice breaks beneath your feet: Your coat and boots fill with water and pull you down. An airlock blows: Vacuum pulls you apart by the eyes, the pores, the lungs. You awaken in a fire: The door and window are outlined in flames. You fall against a railing: The rusted iron slices through your femoral artery. You are dead already.
