Eli5: In movies people instruct bleeding out characters to stay with them and to keep their eyes open. Does falling asleep/ blacking out actually accelerate the process of dying or is that just a movie cliche?
A person awake is easier to see a change in their condition. If a person slumps over, are they sleeping? Unconscious? or dead? A person awake and talking to you is alert, eyes closed and resting things changes get harder to notice.
