aging: creatively?

On the I.N.K. (Interesting Nonfiction for Kids) blog, author Jan Greenberg writes:

"Here is a question that comes up every now and then in my writers workshops with adults. How does aging affect your writing, especially your ability to connect with kids? I usually answer jokingly. “ Who me? Age?” or something to that effect.
Recently, when I was invited to be on a panel, sponsored by Washington University Medical School, entitled “In the Words of the Artist: The Influence of Age on Creativity and Expression,” I was forced to give this subject more thought.

"I mentioned to my daughter that I actually had agreed to participate on such a panel, and she remarked, “Perhaps you’ve decided finally to act your age.” It occurs to me that our children expect us to age gracefully, to age with dignity. What popped into my head was a line from Dylan Thomas’ poem “Do Not Go Gentle into that Good Night.” “Rage, rage, rage against the dying of the light.” Well, forget the rage. I prefer to age creatively."
