I remember a professor of Classics at Heidelberg College, Frank Kramer, who, in his late 80s had the interests and ideas of a young man and the balance of an old. (A good exchange for us, as we age, we trade physical balance for mental balance.) Seat him behind a curtain and ask him any question. He had spent the summer in Asia exploring archeological sites; he was curious about the similarity of problems faced by the ancient Greeks and modern society. And his voice was always youthful and his enthusiasms contagious. From your side of the curtain you couldn’t tell his age.
So with “soft” aging. You can always embrace, for example, the art, the music and the style of each new generation. They heal the broken parts of life (and make stronger the places where the breaks occurred). You can enjoy the new sounds, ideas and expressions that are not really foreign because they spring from that same life force that you tapped into when you were twenty-five.
The young are the reborn; they are us reborn.
We are always, throughout life, alive as conscious dreamers and unconscious spirit.
They say you can be young at heart, but I hear you saying we can be young at thought also.
