"When the dough has doubled in bulk, punch it down." A human baby doubles its birth weight by six months. It's a milestone, an occasion, a passage, like a birthday. Call it First Doubling. May it have its own page in all the world's baby books from this day forth. Call it Punching Down Day.
Most adults stop gaining weight after their fourth doubling. Starting at 8 pounds, they go to 16, 32, 64, 128, and a bit more. Most stop a bit after four; I, after a long pause, kept going until a bit after five. It's exponential.
And me? You thought I was an exhibitionist, discussing my embonpoint so boldly here on the embonet? No. Not an exhibitionist. I'm an exponentialist.
