Pres Uchdorf gave a talk recently, perhaps during the Women's broadcast?, in which he described drinking many cans of a caffeinated soft drink that shall remain nameless, while he tried to learn how to use a computer. As someone who has to keep working till I get the right number, I say drink the Diet Coke. You gotta do what you gotta do. When you graduate, you can become a smug clear eyed health food nut who recommends roasted tofu to everyone and only eats organic till then drink the coke!
