“All I know is that while I’m asleep, I’m never afraid, and I have no hopes, no struggles, no glories — and bless the man who invented sleep, a cloak over all human thought, food that drives away hunger, water that banishes thirst, fire that heats up cold, chill that moderates passion, and, finally, universal currency with which all things can be bought, weight and balance that brings the shepherd and the king, the fool and the wise, to the same level.”
—Miguel de Cervates, Don Quixote, published in 1605
