If man were immortal he could be perfectly sure of seeing the day when everything in which he had trusted should betray his trust, and, in short, of coming eventually to hopeless misery. He would break down, at last, as every good fortune, as every dynasty, as every civilization does. In place of this we have death. ~Charles Sanders Peirce
I like this one. It makes me think that...while dying should be put off as long as possible, if we are happy with our lives when we die, we get to enjoy the best part of life without having to endure the inevitable pain that would have followed it had we lived for a great deal longer. Him, you, her. I think he was happy with you two when he died. I think he avoided the pain that I worry I'll face one day. The pain of losing you.
