Back by popular demand: Joseph Epstein, writing in 2004, on the perpetual adolescent. An excerpt:
Life in that different day was felt to observe the human equivalent of the Aristotelian unities: to have, like a good drama, a beginning, middle, and end. Each part, it was understood, had its own advantages and detractions, but the middle--adulthood--was the lengthiest and most earnest part, where everything serious happened and much was at stake. To violate the boundaries of any of the three divisions of life was to go against what was natural and thereby to appear unseemly, to put one's world somehow out of joint, to be, let us face it, a touch, and perhaps more than a touch, grotesque.
Today, of course, all this has been shattered. The ideal almost everywhere is to seem young for as long as possible. The health clubs and endemic workout clothes, the enormous increase in cosmetic surgery (for women and men), the special youth-oriented television programming and moviemaking, all these are merely the more obvious signs of the triumph of youth culture. When I say youth culture, I do not mean merely that the young today are transcendent, the group most admired among the various age groups in American society, but that youth is no longer viewed as a transitory state, through which one passes on the way from childhood to adulthood, but an aspiration, a vaunted condition in which, if one can only arrange it, to settle in perpetuity.
