Non-clinical Sleep and Wake-up Uses

Famous quotes containing the word sleep:
“A song is no song unless the circumstance is free and fine. If a singer sing from a sense of duty or from seeing no way to escape, I had rather have none. Those only can sleep who do not care to sleep; and those only write or speak best who do not too much respect the writing or the speaking.”
—Ralph Waldo Emerson (1803–1882)
