A great deal of emphasis nowadays is placed on the importance of healthy living: eating the right foods, drinking the right (unpolluted) liquids, taking in as much good clean air as possible at all times, and exercising until the muscles begin to creak. Nutritionists have written millions of words about junk foods, about the critical importance of fruit and vegetables to be taken on a daily basis by everyone in order to keep us free from the ravages of disease. No boozing. Plenty of walking or running and good living. Sometimes it’s hell on earth trying to keep the pounds down by eating well. I believe such an existence can be unutterably boring – after all a little of what you fancy does you good. Or at least not much harm.
