A heroic red blood cell – courageous, selfless, hard-working, picking up billions of oxygen molecules in the alveoli and coursing through the heart and every corner of the body electric feeding hungry tissues
Or a quick bounding platelet – a cohesive force that brings everyone together to bond, hold hands across a gaping wound and save the waste of precious fluids and life itself
Perhaps a mighty macrophage – a giant of a cell, a shape-shifter and relentless pursuer of evil, patrolling the body, taking care of its enemies and protecting all
Or maybe a noble dendritic cell – the sentinel, the informer, the presenter of infectious evil to everyone in the immune world
Perhaps you would be a stem cell – the creator, progenitor, mother, artistic source of all blood cells
Which one would you be?
