"The message of sunset is sadness; the message of dawn is hope. The rest and the spell of sleep in the middle of the day refresh the human frame far more than a long night. We were not made by Nature to work, or even play, from eight o’clock in the morning till midnight. We throw a strain upon our system which is unfair and improvident. For every purpose of business or pleasure, mental or physical, we ought to break our days and our marches into two."
