We have all read the children’s books telling us to count the sheep jumping over the moon to get to sleep. Who would have thought the actual tale of counting sheep could be traced back to ancient shepherds, who literally had to count sheep before they went to bed to make sure their flock was all there. Since the counting took place at night time, the Shepherds were so tired once they got in, it eventually turned into a night time sleep aid story according to Matt Soniak of Mental Floss.
