I was reflecting on what retirement means to me. Becoming a new entrepreneur at 70, launching my podcast Growing Older Living Younger 6 years later, and of course writing this book, kept me optimistic, happy and energized, and sustained me through the dark days of the pandemic.  Active retirement provides a path to aging that is rich in mental, physical, social and cultural growth.
