My aunt could do this with ease even well into her late 80's. It was so easy for her she didn't even think about it, but would just pop up from the floor this way after playing with her great-grandchildren. And me with my bad knee? Probably never.

Though of course my aunt (my mom's big sister) never really had a weight issue either. Though I do recall that in her early 70's, on her 50th wedding anniversary, about all the weight she had put on over the years. She was 5'4", and as she said sadly about it "on my wedding day I weighed 99 pounds, and today I weigh 124. In 50 years I have put on *25 pounds*!"
