Actually, there is no time to start a diet. Diets presume deprivation of the pleasure of eating tasty food, like turkey, sage dressing, cranberry sauce, mashed potatoes, pumpkin pie, pecan pie, whipped cream, and I could go on. At my age, however, diets are somewhat anti-climactic. I am already considered by some to be past my expiration date. This confers some freedom in dietary choices, a freedom that I plan to exploit at every opportunity. So, bicycle guy, deprive yourself as much as you want. I will live joyously for the both of us.
