" She was fast approaching thirty, and with that impending birthday the way she thought of her own life was beginning to change. When she was twenty, she thought of people in their thirties as, well, old: after all, they had lived as long as she had and half as long again, and so they must have been tired, with the beginnings of aches in their bones and the first intimations of their own mortality.
But the peculiar horror of growing older was not what she expected. In fact, she felt the same age as she had eight years ago, and twenty-eight years of life had managed to compress themselves into a life-span that once comfortably held twenty. It wasn't that she was getting older, but that the years were getting shorter, and were therefore more precious. You had to use them sparingly. "
