I said there were two facts and then got lost in the telling of the first. This is the second fact: Our lives are much longer now. In some strange way which no one pretends to understand, the process of aging, if not halted, has been slowed. I have not seemed to age at all, nor have any of the others, in these last fifty years. If there are a few more white hairs I cannot detect them; if I walk a little slower after fifty years I am not aware of it. I was sixty then and I still am sixty. The youngsters develop to maturity in the usual manner and the normal course of time, but once they reach maturity, the aging seems to stop. Our twin grandsons, whose twenty-first birthday we observed fifty years ago, still are twenty-one. They are, to all physical appearances, the same age as their sons and their oldest grandsons and at times this becomes somewhat disconcerting to someone like myself, who has lived his entire life with aging, and with the expectation of it. But disconcerting as it may be, I do not quibble with it, for with the inhibition of aging has come, as well, unbelievable good health. That was something that had worried us to start with—with all the people gone, what would we do for doctors or hospital care if we should happen to fall ill? Luckily, perhaps, the chronological years during which a woman remains capable of bearing children are about the same as they were before the span of life was lengthened. The female reproductive system apparently exhausts its supply of potential egg cells within some thirty years or so, as it did before.
