In this fascinating New York Times Op-Doc, noted photographer Phil Toledano takes us on precisely this 3-year journey within himself, confronting all the various ways he can grow old, disease, wither, and die. At first blush it seems like Mr. Toledano's project was custom-designed to address only his deep fears and neuroses. But don't blink, or you might miss the ways his project speaks to what is universal in each of us.
