My father got polio when he was 6 months old. Both of his legs were skinny bean poles and both of his feet were crippled beyond belief.
When he needed shoes,,he would send me to the store to order them. His size was 6E/EEEE. They were like square boxes.
He died when he was 85. He always slept on the floor and he could always get up easily.
I have a knees with a replacement that makes it difficult to get up off of the floor, but i can sit with my legs crossed on the floor. I can get up, just not too fast.
My husband who is 70 can sit on the floor with crossed legs and he can get up just like a kid could.
Nancy is a young woman. I would guess most people her age can sit on the floor and get up quickly. All my adult kids can...age 49, 42 and 43. ...and my 49 year old has MS.
I am not impressed. What she can do is normal for somone her age with no ortho problems. I think Rick D is 62 and he sits on the floor too.
