And, on a wide view, I could see that it makes little difference whether one dies at the age of thirty or threescore and ten—since, in either case, other men and women will continue living, the world will go on as before. Also, whether I died now or forty years hence, this business of dying had to be got through, inevitably. Still, somehow this line of thought wasn't as consoling as it should have been; the idea of all those years of life in hand was a galling reminder!
