He is fortunate to still be able to take advantage of the opportunity of making some money through fighting.
This is a good fight that he can win. Francis made so much money from just his two fights even though he lost, shows that there is enough money to be made from boxing.
Tyson is doing the fight for both money and ego.
I adore how Mike Tyson is doing all in his power to resurrect his former self, and even at his advanced age, the man still has some moves. And the reason the man is receiving inspiration is due to the benefit of earning that kind of money. Since Mike Tyson last fought, he has been training again and is determined to win at all costs. This match will be well-attended because fans from all over the world will be watching, and you can only image how much money many will make from simply betting on it. Boxing as money receiving those blows are not for free. And even if any of them should lose they will still make there money. I hope that ego does not take over him during the match if not it won't end well for him. But if it was for the money then he needs it. Because everyone needs money.
