"But doctors talk about cells as if they had such unlimited importance all by themselves. As if they didn't really belong to the person that has them." Teddy brushed back his hair from his forehead with one hand. "I grew my own body," he said. "Nobody else did it for me. So if I grew it, I must have known how to grow it. Unconsciously, at least. I may have lost the conscious knowledge of how to grow it sometime in the last few hundred thousand years, but the knowledge is still there, because—obviously—I've used it."

I rolled back onto the lawn and pressed my forehead to the ground again and made the noise that Father calls groaning. I make this noise when there is too much information coming into my head from the outside world. It is like when you are upset and you hold the radio against your ear and you tune it halfway between two stations so that all you get is white noise and then you turn the volume right up so that this is all can hear and then you know you are safe because you cannot hear anything else
