I agree that frailty is an important factor, as is attitude. I turned 70 this year, and my internal self was amazed at "that BIG number"! I think my inner child thought that I would be my grandmother, or my mom at this age, and has been so surprised that I am still my same old self!! WHEW what a relief that is! I still love movement and quilting and eating. And I feel blessed in so many ways. Sending love to you all - young and old!
