One day, in the (hopefully) far distant future, my heart will issue its last, vital beat, my lungs will resign from their tediously repetitive job of inflating and deflating to provide me with oxygen, and, in quick succession, every organ, system, and function within my body will shut down, never to be restarted. The deafening noise of the trillions of explosions in my brain will go quiet, and the light that lives just behind my tired eyes will go out for the last time.
