Recently I was at a family gathering with several adults (me being the oldest, at 64), a few teenagers and a toddler. My grand daughter and her 2 friends challenged each of us to walk with a book on our head and see who would succeed, and laugh at those who didn't.
Everyone's jaw dropped when I was the ONLY one who could do it, and I even added a curtsy at the end! I said: "Thank you, Fitness Blender "
A milestone? To those in that room....yes!!
