Even physically impaired people can learn judo and take part in the Paralympics.
One of the greatest benefits of judo as a sport and for self-defense is that it has very little physical limitations in terms of technique; Judo incorporates techniques that can be performed by an average person. Due to the lack of kicks, punches and other kinds of strikes, almost anyone can learn and apply judo techniques, let it be a man, woman, old, young, non-athletic or superior athlete. Even physically impaired people can learn judo and take part in the Paralympics. The lack of punches and kicks can be overcome by cross-training in some other martial arts such as karate.
