Marcus Aurelius
Meditations 9.33
All that thou seest will quickly perish, and those who have been spectators of its dissolution will very soon perish too. And he who dies at the extremest old age will be brought into the same condition with him who died prematurely.
Marcus Aurelius, Meditations 9.33, translated by George Long
All that thine eyes behold will soon perish and they, who live to see it perish, will in their turn perish no less quickly; and he who outlives all his contemporaries and he who dies before his time will be as one in the grave.
Marcus Aurelius, Meditations 9.33, translated by C. R. Haines
