The Short Answer
If you mean the immediate why, a blow to the carotid sinus nerves can cause an immediate drop in blood pressure that makes you faint. If you mean the teleological why, what benefit comes from it that evolution selected for this trait, we can only hypothesize: – If you're attacked by a predator / dangerous herbivore, appearing to die may cause the animal to lose interest before doing fatal damage. – If you are relaxed in a physical situation beyond your control, like a rockslide or something, it's less likely you'll go into shock and suffer certain musculoskeletal injuries. – If you're doing something dangerous that may cause brain trauma, a hard reset will prevent you from continuing the stupid thing and possibly convince you to change course of action when you wake up.
