There is a sweet spot at the nape of your neck, two fingerbreadths up from that bony bump. When a thin sharp object like an icepick or a stiletto is plunged in there, midline, your spinal cord will be severed but no major arteries will be touched. This will make you instantly quadriplegic but you will still remain alive and be able to breathe on your own.
The sensation to your face, eyes, and teeth directly comes off the trigeminal nerve (brainstem) so it will also remain intact. This means that you will still feel all the effects of the acetylene torch and power drill.
Sleep tight!
