Would he keep fighting till he's 50 like Evander ? Would he be a commentator ? Trainer ? Promoter ? Referee ? Ring card girl ? One thing is for sure with his charisma and wit the guy would be a great ambassador for boxing.
If Ali didn't get sick there would be more fighters willing to die like Biggie in the ring. The truth of the matter is that the neurological problems suffered by high-profile, TV era fighters {Ali, Frazier, Quarry, etc etc etc} has made fighters cautious and more health-conscious. There are exceptions- Gatti, for instance, who is, you may have noticed, dead. Ali, if he had remained comparatively healthy, would have fought on until he no longer remained healthy or capable of demanding large purses, two events which I feel would have coincided with each other as a rule. He took the Holmes and Berbick fights principally for money, money to deal with his marital expenses, entourages, high cost of living etc. He only got well paid for those fights because he maintained the illusion, via Spinks II,shattered forever by the Holmes fight, that he was capable of miraculous comebacks and of beating any man, anytime. To cut a long post short, if the Holmes and Berbick fights didn't finish him, then the Tyson fight would have, and he'd have gone on to become the shell of a man he is today. In other words, once Ali was born and took up boxing, he was pretty much fated to get sick.
