This lady may not have (yet) reached the other's age, but I LOVE her way of staying young and limber through YOGA.
I used to do all those stretches with ease (and more), but never again since my spine was encased in a titanium armature.
I suspect I have Ehler's Dehlers hypermobility Syndrome (the kind where you're extra stretchy). I thought it was enviable from Jr High on up, but not now. I think it was the result of that hereditary disorder - not my daily exercises. In those days they didn't check school-children for scoliosis and the like.
Have a look.
