Now, blessings light on him that first invented this same sleep! It
covers a man all over, thoughts and all, like a cloak; it is meat
for the hungry, drink for the thirsty, heat for the cold, and cold
for the hot. It is the current coin that purchases all the pleasures
of the world cheap, and the balance that sets the king and the shepherd,
the fool and the wise man, even.
-- Miguel de Cervantes (1547-1616)
-- Don Quixote, Part ii, Book iv, Chap. lxviii
