Most people experienced this with Mike Tyson I believe. I mean Mike is an old guy, out if the blue he decided to fight that young boxer, Jake Paul. Jake is well built, young and trained. Mike is a legend but old and no matter how much training he does, he won’t get any younger.
Some people made a bet on Mike’s victory. The nostalgia fooled them into thinking Mike could win. Didn’t happen.
What if it's a staged one? To be honest, I thought Mike Tyson was winning that fight but then the reality hit me harder.
It is better to avoid such bets, there's highly that the what will be the outcome of those match can be manipulated in a way that someone wants because it's all money not really the pride of sports at that point so avoid betting on special matches unless the competitors are equal in terms of age, level of their game, etc.
The outcome will be different if it's a staged one which the bet they made is because of nostalgia. Well, getting old means that you are not in your prime even if you have some good record or a legend in a sport although it may be different like what Jawhead999 explained where the person is not motivated and the first priority is to make money. I guess that's the reason why pros retired since they are no longer the same as before which their goal is to become the best at what they do.
