Originally published October 30, 2002. I recently celebrated my 55th birthday. I use the word 'celebrated' advisedly. This is the first birthday that has mentally challenged me. Twenty-five was a positive milestone. Thirty, Forty and Fifty were all acceptable because, being in the media business, I justified to myself that I remained within the boundaries of marketing desirability and demand. But now I am no longer 25-54. I have, with the passage of one day, transferred from youthful cohabitation with 25-year-olds, to the never-never land of 55 plus. In the minds of advertising media buyers, I have become old and irrelevant. Of course, I still feel young; in fact, younger than ever.
