If you, like many I’ve read, admire Doc’s attitude (as portrayed by Val Kilmer below, at least) then please consider this:
“Tsunetomo believed that becoming one with death in one’s
thoughts, even in life, was the highest attainment of purity
and focus. He felt that a resolution to die gives rise to a
higher state of life, infused with beauty and grace beyond
the reach of those concerned with self-preservation.”
– Wikipedia on Yamamoto Tsunetomo
Doc WAS dying, but still, I think there’s a point there.
