as i've gotten older as a fan and watched some greats die, or have health problems, I no longer think the sport is only bad for the brain. I believe the attrition of it all an the bodies ability to recover an repair has a limit for each and every person an It must takes years off their lives, the average lifespan for boxers is 67 and with the brain issues, often those aren't good years for these men. Anyway, body shots are still damaging and ribs will still get broken, so there goes your bright idea that you can always go to work the next day. I have have had broken ribs before and I was a college student and I showed up to class and grunted as I felt my ribs pop back into place, looking back, I thought somethiing like that was unfair to the other students around me, and if I'd had a physical job, expectiing help with my work wouldn't have been fair to everyone else.
People will always come up with bright ideas but the sport will never be safe an risk free unless you come up with some fake AI version of fightng.
Ali had a personal doctor who quit on him after he advised him to retire because he ran some tests and found that Ali's kidneys were deteriorating. Mayweather berates Ali for losing to Spinks, not acknowledging all the previous damage from the ammies, the monsters he had to face, the worst line of destroyers any great heavy ever had to beat which is just petty. Roy Jones is trying to fight him over that but it's not necessary. Floyd didn't have killers that he beat all throughout his career, that simple. Liston, Frazier, Big Cat, Shavers, Foreman, all capable of kayoing any other heavyweight who ever live, and that's not to mention the Nortons, Lyle's, Coopers etc..,
