Death from Old Age

Death caused by the natural aging process rather than by injury or disease.

By the time of Operation Snake Eater, the centenarian sniper, The End, had very nearly reached the end of his lifespan.

In ordinary life, he was practically dead already, barely moving or speaking, waiting for one last battle worthy of what little life he had left.

At last, The End got the battle he was waiting for when he faced Naked Snake, The Boss's final disciple.
