Many years ago, Gloria and I used to go to the disco most Friday nights, where we got on chatting terms with a couple called Liz and Dave. Both Gloria and Liz were slightly overweight, and used to swap various dieting tips between dances. Sadly, Dave died, so we didn't see Liz at the disco for some weeks, but when we next saw her, she had lost quite a bit of weight. I assumed that this was caused by grief, stress, etc, but Gloria told me later that shortly after Dave's death, Liz had tried a variant of the Atkins diet. This, apparently involved eating nothing but pork, until you had consumed at least a ton of the stuff. Gloria was so impressed that she tried it, and it worked. And that is -how Liz, the widow of our discotheque, made Gloria slimmer by this ton of pork.
