"Eventually blood cells are like the last laugh of a marathon, but instead of a victorious finish line, they're sprinting to the nearest hospital. Imagine it: 'Eventually, after years of traveling through capillaries like a tortoise in a sprint, the blood cells finally decide to take the scenic route to the bloodstream, where they're greeted by an urgent sirens and a medevac drone!'"
