The point of pain where your body shuts down is actually not that bad. I could watch myself die no problem. You don’t really experience death anyways. Your consciousness exists in user space but your body functions in kernel space. If kernel space dies, you don’t even get a memo. It is all kinda shocking and hard to take in when a super traumatic thing happens like breaking your neck back and a bunch of other stuff. It is like you are not part of it. The pain kinda just fades into a noise you barely hear your own thoughts over. I’ve been damn close to dead, and only barely recall little bits and pieces while missing most of three hours. I’ve watched people die from far far less severe injuries. They did not see their kernel space fail. So yeah I don’t think it matters. Smaller injuries hurt worse most of the time. The really big stuff passes a threshold where pain is kinda irrelevant.
