This is not to say that nostalgia is our inescapable fate. The lesson I am trying to draw from reflecting on the examples of Snowden and the N.F.L. is not that the thrill ends early. Rather, in their extremity these examples bring out something else. For most of us, as our lives unfold we simply do not, we cannot, know whether we have peaked in an area of our lives — or in our lives themselves — in ways that are most important to us. The past weighs upon us, not because it must cancel the future, but because it is of uncertain heft.
~ Todd May, from The Weight of the Past
