Dr. Lin: I want to assure you both that there is nothing debilitating about your son's condition. He's totally healthy, normal in appearance, alert and quite happy. However, his cells are developing at what we feel is four times the normal rate. Even though your son was only 10 weeks old when he was born, physically he was nine months and ready to leave your womb. Dr. Benfante: Nature has given us all an internal clock. It meters out lifespan; controls our growth. Your son's internal clock seems to be ticking faster than usual.

I want to assure you both that there is nothing debilitating about your son's condition. He's totally healthy and normal in appearance, alert and quite happy. However, his cells are developing at what we feel… Is four times the normal rate. Even though your son was only ten weeks old when he was born, physically, he was nine months and ready to leave your womb. Nature has given us all an internal clock. It meters out life span, controls our growth. Your son's internal clock seems to be ticking… Faster than usual. - But he's healthy? - Absolutely. I'm sorry. I still don't understand. I've never heard anything like this before. Well, quite frankly, neither have we. There are other aging syndromes that we know of. Progeria, for example, which is very devastating to the child, but… Jack's cells are replicating at an unheard of rate. Is he gonna age like this the rest of his life? Sir, this is only speculation. But, uh, we feel that at age one, your son may be physically around age four. And if this continues throughout his life, by the time he reaches age ten, well, he could… Appear to be an ordinary, full-grown, 40-year-old man. Are you serious? Baa! That's where he lives. Right there down the street my whole life, and I didn't even know about it.
