Never have I enjoyed youth so thoroughly as I have in my old age. In writing Dialogues in Limbo  The Last Puritan  and now all these descriptions of the friends of my youth and the young friends of my middle age  I have drunk the pleasure of life more pure  more joyful than it ever was when mingled with all the hidden anxieties and little annoyances of actual living. Nothing is inherently and invincibly young except spirit. And spirit can enter a human being perhaps better in the quiet of old age and dwell there more undisturbed than in the turmoil of adventure.
George Santayana
