“[...] the absence of sensation can be devastating. But an absence of pain – the loudest of our sensations – sounds like a blessing, not a curse. Pain screams its way into our consciousness, blotting out everything else. The blinding sear of stubbing one’s toe, cracking one’s head, or cutting your finger, elbows all other sensations and senses out of the way, demanding immediate attention and action.”
