Shirley W. Mitchell

Shirley W. Mitchell is the grande dame of positive aging.

She is the author of the books "Fabulous After 50" and "Sensational After 60," and as she approaches 70, she's planning her next book.

She's also a motivational speaker and the host of a weekly Internet radio show, Aging Outside the Box.

She says she didn't have many positive aging role models when she was a girl, and she hopes women today continue to shine the light on the great aspects of growing older.
