I once succumbed to the fad of fasting and went for six days and nights without eating. It wasn't difficult. I was less hungry at the end of the sixth day than I was at the end of the second. Yet I know, as you know, people who would think they had committed a crime if they let their families or employees go for six days without food; but they will let them go for six days, and six weeks, and sometimes sixty years without giving them the hearty appreciation that they crave almost as much as they crave food.
