>>23066064bleeding out is probably the quickest and most peaceful way to die
trauma or some shot to the brain/spine might be more instant but dont underestimate how fucking painful the nervous system shock could be
most drugs will end with muscle spasms and your body desperately trying to fight to be alive while it very slowly dies off (same with asphyxiation)
but in bleeding out everything just goes black and your cells start dying
sure the cut seems painful but it wont be as painful as other kinds of trauma and it wont hurt for a very long time
