Athlete Aimee Mullins

“Born without fibulae in both legs, Aimee’s medical prognosis was discouraging; she was told she would never walk, and would likely spend the rest of her life using a wheelchair. In an attempt for an outside chance at independent mobility, doctors amputated both her legs below the knee on her first birthday. The decision paid off. By age two, she had learned to walk on prosthetic legs, and spent her childhood doing the usual athletic activities of her peers: swimming, biking, softball, soccer, and skiing, always alongside “able-bodies” kids.”
