It"s a safe bet that David Joyce knows more than you did when you were his birth age. That"s not hard, since what you knew back then was pretty much nothing at all. You knew warmth, you knew darkness, you knew a sublime, drifting peace. You had been conceived 29 weeks earlier, and if you were like most people, you had 11 weeks to go before you reached your fully formed 40. It was only then that you"d emerge into the storm of stimuli that is the world. No such luck for David. He was born on Jan. 28—well shy of his April 16 due date—in an e-mergency cesarean(剖腹产的)section after his mother had begun bleeding heavily.

Under their care, he had grown to 18. lin.(46cm)and weighed 51b. 11.5 oz.(2594g), nourished by breast milk from his mother, which was fed to him through a nasogastric tube(鼻胃管)threaded through his nose to his stomach. David"s father and mother live 90 minutes away in Randolph, Wis. They had been at the hospital every day after work for 51 days straight at that point—a three-hour round-trip—to spend a few more hours with David. We know from the text that______.
