With each pint of blood pumped through the superior vena cava, I die a little.
As the blood rushes into the right atrium, and is then forced past the tricuspid valve into the right ventricle, my body gives out a little.
When this blood is pumped out into the pulmonary artery, and more is brought in by my pulmonary veins, I age a little.
As this blood enters the left atrium, and is pushed past the mitral valve into the left ventricle, the lights fade a little.
When this blood enters my aorta and is pumped out into my body again, I grow a bit farther away.
Everytime my heart beats, I die.
