"He was forty, which is the most frightening age in life. You don't feel sorry for the old, because they are old already; you don't feel sorry for the dead, because they are dead already. But you do feel sorry for those approaching old age, those approaching death. Forty! At fairgrounds you see roller coasters dashing up a steep slope followed by a steep drop and then another ascent. At the top of the slope, or rather just before the top, the vehicle has used up all the energy it acquired in the descent and it slows down and hesitates as if the top were unattainable, as it it were terrified of the approaching plunge. The man approaching forty is in a similar state of hesitation and uncertainty; his pace slackens, he is paralyzed by the approaching summit and the descent he cannot see but knows lies just ahead."
