Who Rules The Body?

“Who rules the body, the heart or the head?
Perhaps it is both, for with neither, we’re dead!
But then, so many parts, without which we would die
And others, like hands, upon which we rely
You can live without eyes, or a tongue, or an ear
Sure, it is nice, if you can see, taste or hear
Fingernails aren’t life-threatening parts in the least
Until they’re clipped during dinner, then you’re as good as deceased.”
I blinked the blood out of my eyes and looked up at the torturer.
“Please kill me before you read me another of those.”
