In the last years of the boxer's life, Muhammad Ali had Parkinson's disease, diagnosed in the early 1980s. In 2010, he went to Israel to be treated for the disease. The work was done with adult stem cells. The tests carried out so far with mice were successful, but their effectiveness in humans is yet to be tested. In 2001, Will Smith played Muhammad Ali in the movie Ali.
Several times, the fight between Ali, the world champion of professionals, against the Cuban Teófilo Stevenson, world champion of the amateurs and Olympic champion, was announced, but, due to technical and political problems, this fight never took place. In 2010, Muhammad, along with singer Christina Aguilera, promoted the victims of the earthquake that destroyed Haiti.
Ali was considered one of the greatest icons in boxing history!
