Steady of Age

I've been having a Jane Austen weekend - watching the movies "Becoming Jane" and "Persuasion" and listening to the audio book of Persuasion. One quote from the book cracked me up. They described her as a Baroness "Steady of age and of character." What a great way to describe this current developmental stage where I find myself. Here is the new about me fact:
I am steady of age and of character.
