ABOUT TWENTY YEARS AGO—AROUND THE TIME OF HIS HUNDREDTH birthday—Dr. Hu Noah (like all Ivyns, he put his family name first, because it was somehow supposed to be more logical) had made a conscious decision to give up on trying to explain to younger people just how little he had actually changed with age. It didn’t really matter that these people were making all sorts of wrong assumptions about how his mind and his body were changing. What mattered to them, he had finally come to realize, was that they believed such things to be true. It was more important to them to believe it than it was for him to explain the facts of the situation, and so he had decided to let them think what they thought and to try to find constructive ways to use it. Sometimes this meant sitting so quietly that they forgot he was there and began speaking of him in the third person, using Remembrance as a sort of interpreter. Sometimes he could astonish by speaking up, making it clear that he had been following the conversation all along. Or he would stand up—an action that was always described later, by witnesses, as "springing to his feet" even though it was nothing of the sort—and begin to move about under his own power, which many who didn’t know him well seemed to consider miraculous. Because Remembrance was always by his side, and his grabb was always scuttling along beside him, giving him a sort of universal banister and grab-rail, people assumed he was more unsteady than was really the case. In fact, this support system was nothing more than a simple way of playing the odds. A fall could cripple or kill him; why not have the grabb handy? And Remembrance, though she was assumed by most to be a health care worker, was really more of a general-purpose aide de camp and, to put it crudely, a cowcatcher for turning human obstacles out of his path.
