Dear Eduardo, The reason for my chubby calculus is that I do the cooking at my house. Like my dog Jacob, I have a tendency to prefer high-fat dairy products to the low-fat varieties. Blame it on Pythagoras. The Pythagoreans forbid eating beans. I'm certain this leads to chubby calculus. To accompany lamb dishes or to enrich and thicken fresh soup (or boiled beef), I often use beans. Unlike David's dog, I have never been able to achieve a proper form. Fortunately, my tall, elegant wife has a fondness for short, slightly chubby calculists who are losing hair and growing long in the tooth. Along with the dogs in my pack, Ditte likes my cooking. Somehow, her form never changes, while mine does. Yours, Ken Eduardo Corte-Real wrote: “your calculus seems a bit chubby.”
