Thin as a Slab of Tofu

If you’ll check it, the distance of the human heart to the exterior of the skin of the chest is only a little over an inch and a quarter. About the same thinness as a slab of tofu. Nothing much. I have read others and I am currently reading a famous story in which I can’t figure out who to root for. I just don’t care about any of the characters. You may call your character a robot or a mouse or (most original I’ve heard lately) a “glitchling” – the creatures that cause dropped calls, lost e-mails and dead letters. But no matter what you say, you are writing about a being that ends up with humanlike responses. As the story teller, you MUST find somewhere a buccaneer’s cutlass and slash your protagonist’s chest to the bone. You MUST lay open your character’s chest and cause your reader to see that tiny Cardium beating in there, so determinately and hopefully, behind the white grid of the rib cage.
