"Youth, Day, Old Age, and Night"
di Walt Whitman (1819-1892)

Youth, large, lusty, loving -- youth full of grace, force, fascination,
Do you know that Old Age may come after you with equal grace,
force, fascination?
Day full-blown and splendid -- day of the immense sun, action,
ambition, laughter,
The Night follows close with millions of suns, and sleep and
restoring darkness.
