I stand, a cyborg micronaut, in front of the biggest human heart any person has ever seen.
It is Arch Obler huge, a flesh pump the size of a skyscraper, but I manipulate it with god-like facility, rotating it in midair with my hands and bisecting it with just a flick of the finger. Through ventricles and thundering aorta I dive, floating through heart chambers so enormous, they become corpuscle cathedrals.
