On "Mad Men," when Don Draper was pitching for the Kodak account, he played with the theme of nostalgia. That was a different time. At that time there were few old professionals in the workforce. Organizations gave them pensions and they vanished from sight.
Now, there are many of us old professionals out there hustling. And we sure don't want to be seen as "old." The objective is to come across as important, influential, and of commercial value. The Clintons, Rupert Murdoch, and Betty White are among those who pull that off.
When they address groups, they are in the now. They hold back the nostalgia, personal and national. If they reach back into the past, the journey is short. It was print queen Tina Brown, famous for restoring VANITY FAIR and THE NEW YORKER, who told a writer to have less past in an article and more present.
In addition, they aren't sheepish about age. They manage to lift themselves out from that category or, like White, exploit it for positive branding. She has become famous for referring in baking demonstrations to her "dusty muffin."
And, the ageless resist the siren of a comfort zone. Instead they are full of surprises. That's exactly why they are in demand with audiences.
