Time, of course, is the merciless slaughterer of all these infinitely qualified anchors of the meaning of life. Wait long enough, and every truth will crumble. Wait long enough, and every value will dissolve into moral ambiguity. Wait long enough, and every habit will decay, first into ritual, then into farce. Wait long enough, and every slain demon will rise again. And then you will be free. Something almost nobody wants, but almost everyone is forced to endure past 40.
