We wouldnt able to tell on what are those possible effects but its true that implications do really always come in last which means it is unknown until it would come out and would be known publicly about health conditions which is something a very common issue into aging boxers or to those who had retired.
This is one of the cons or something to be paid up after all the years that theyve been doing boxing or sticking into this career but well its their choice to make though and its their body to be handled.
I agree into that words about respect on which Wilder did really accepted his defeat and didnt say any bullshit reasoning just like on what he had done in the past.
It isn't just boxers, but it's a sport wide concern at the moment. More research needs to be done, and there isn't a lot of concrete evidence out there currently, at least not that I'm aware of. However, I know those that regulate football competitions have come under pressure to prevent heading the ball recently, I think that's probably a little too extreme of a restriction, but I can see why boxing, MMA, and high impact sports are detrimental to the athletes health. Well, we know that boxers have had brain damage, and various permanent damage done, so it's definitely an issue.
Getting knocked out isn't really a natural thing either, Yeah our body knows how to cope with it, and switches off our conscious mind, but it's still working in the background keeping everything in check. So, getting knocked out while not really a natural or expected thing doesn't always mean there's permanent damage being done, however Wilder in the second, and this recent fight took a lot of damage.
I respect the man for taking a beaten, because that's practically what it was outside his two knockdowns, but he probably did himself more harm than good by staying on his feet so long. If he had woken up in time, and could stand I think he would have tried to get up from the knockout blow too if the ref gave him the chance.
