I stopped buying sugared soda for the house ages ago. Even when I had the metabolism of a man in his mid-Twenties, some sense of self-preservation noted that drinking as much as a liter of Coke a day was incompatible with long life. It’s a hazard of self-employment. One likes to have a tumbler of drinkable liquid at hand and when the tumbler is empty, it’s a wonderful excuse to walk away from the keyboard. It’s why successful crime novelists are alcoholics.
