In our day to day routines, we feel our lives most when they are running out; as we age, as we lose our physical abilities, our health, and of course, family members and friends who are important to us. Then we pause for a moment, sink into ourselves and feel: here was something and now it is gone. It will not return. And it may be that we understand it, truly and deeply, only when it is lost.
David Grossman, New Yorker, "The Age of Genius", June 8/14, p. 70.
