The Heart Wants What The Heart Wants.
Oh shoot... not again! These dang veins and arteries keep multiplying and twisting themselves through my skeleton, tightening their grasp on bone like roots around rebar! I know it's just my goofy old heart trying to gain purchase, that it can thrust itself out with enough force to crack my sternum and escape the blackened hellscape of my diseased chest cavity; but dang it, I sure do like that feel of thick and grimy blood pumping sluggishly through my useless body!
If I go without sleep, I should just be able to tear out the new arteriovenous webbing from my guts about as fast as it grows in, and keep Hearty from absconding from its horrible perch. Nothing doing, old friend!
