Kathleen, thank you so much for your kind words.
Identifying a neighborhood that's perfect for you depends on so many things.
I really don't know of any one neighborhood that might fit your needs off the top of my head. My subdivision, Brentwood (in North/Northeast Raleigh), has empty nesters (including yours truly) and is convenient to everything, but there are many, many areas around here that might fit the bill.
You might ask your friend in North Raleigh for suggestions or maybe others on this board can chime in.
As far as reinventing yourself -- think about Grandma Moses. She reinvented herself in her 70's when she began painting:

My psychology professor in college went back to school at age 50 to become a psychologist; he had been a caterer! There's someone in our neighborhood who was a journalist and became a lawyer in his 50's.
It's never too late to reinvent yourself, careerwise or otherwise. We're just all going through yet another of life's passages. I think this is one passage where we have more power and control than any other (less family pressure, fewer family obligations, and many people have fewer financial concerns).
It's not easy, but it's possible. During these economic times, I think people of all ages are in some way reinventing themselves.
As that old cliche goes, "Today is the first day of the rest of your life."
