A cursory Google search on the subject of sleep will instantly regale you with a wealth of trivia on the subject. 12% of people dream entirely in black and white. Two thirds of a cat's life is spent asleep. A giraffe only needs 1.9 hours of sleep a day, whereas a brown bat needs 19.9 hours a day. Humans spend 1/3 of their life sleeping.
