" This is the way that it goes. In your mid forties you have your first crisis of mortality (death will not ignore me); and ten years later you have your first crisis of age (my body whispers that death is already intrigued by me). But something very interesting happens to you in between.
As the fiftieth birthday approaches, you get that sense that your life is thinning out, and will continue to thin out, until it thins out into nothing. And you sometimes say to yourself; That went a bit quick. That went a bit quick. In certain moods you may want to put it a bit more forcefully. As in: OY!! That went a BIT FUCKING QUICK!!!.... Then fifty comes and goes, and fifty-one, and fifty-two. And life thickens out again. Because there is now an enormous and unsuspected presence within your being, like an undiscovered continent. This is the past. "
