He was more than a fighter, he stood up for what he believed in. There is evidence for this in his refusal to fight against the Vietnamese in the war with Vietnam in the 1960s and early 70s. A great champion who took too much punishment and fought too many fights. He should have been prevented from carrying on his career as a fighter but was probably allowed because too many people would have lost out if he stopped. A great shame we have all been deprived of his spirit and intelligence.
