If you want to figure someone out quickly, tell them that they can’t do something and see how they react. Gabi Schull had cancer as a young child and as a result part of her leg was removed. The doctors took the lower part of her leg, turned it backwards and reattached it to her upper thigh so her ankle could act as a knee.
Gabbi learned to walk and dance again, which in itself is a phenominal achievement. But she still missed being able to dance on pointe. Impressed by her determination, Keith Andrews, a prosthesist, designed her a special leg complete with pointe shoe.
Watch how it works in this video which is really quite amazing.
