Is there a cut-off point for how much pain we can feel? Like, say if you cut off a finger, you’d feel a certain degree of pain; if you then chopped off another one, would the pain necessarily double? Would chopping off ten fingers be ten times as painful? If you chopped an arm off after all that, would it even register?
Do different pains have different thresholds (say the pain of a pierce wound versus a serious burn)?
Can one die solely from pain?
