Sooner or later, all fighters get the message that it's time to retire.
Count Shane Mosley in the group who will get the message later.
Mosley won a decision over a fighter named Pablo Cesar Cano on Saturday. It was Mosley's first victory since 2009 and the narrow decision was enough for Mosley to send out an Instagram announcement that he was going to continue his boxing career and he has no plans to retire yet.
Mosley (47-8-1) has been fighting professionally since 1993. He fought as an amateur long before that. He is 41 years old and he has little of the speed and quickness that marked his prime fighting years.
But it's hard for fighters to say goodbye, especially for those who have been champions and among the great pound-for-pound fighters of his era. Fame is addicting to all athletes; boxers seem to get caught in its anaconda-like grip more than most.
Some of the most noteworthy fighters who stayed around too long include Joe Louis, Muhammad Ali, Roberto Duran, Sugar Ray Leonard, Evander Holyfield and Julio Cesar Chavez.
There's one obvious reason that boxers refuse to hang up their gloves once their reflexes start to dull, their speed starts to wane and their combinations lose their sting.
Mosley, who has been through a divorce, said on Twitter that he still has enough money and he is not forced to remain in the ring to survive economically.
It's the public adulation—or the memory of it—that keeps fighters putting their bodies at risk.
Mosley has to know his days of fighting Manny Pacquiao, Floyd Mayweather and Saul "Canelo" Alvarez are over.
His victory over Cano was about one year after Alvarez trounced him and took a lopsided decision. Pacquiao took him apart in May, 2011 in a one-sided decision. Mayweather did the same to him in May, 2010.
Mosley has not won a fight since he pounded out a TKO over Antonio Margarito in September, 2009. Mosley is 3-4-1 in his last eight fights.
Mosley could put himself on a dangerous path. If he decides he can work himself back into contention by beating inexperienced or lesser fighters, he could eventually get himself a higher profile fight.
What happens then? What happens if he gets back into the ring with an angry and motivated fighter like Robert Guerrero or Devon Alexander? That's when Mosley could find himself flat on his back and in serious trouble.
That's how older fighters get hurt badly.
But Mosley, who once had a dominating skill set, is not worried about that. He wants to keep fighting and he's not worried about the consequences.
Some promoter will always give Mosley a chance to get back into the ring. Until he stops selling tickets.
When the public stops responding to him, he'll be forced to say goodbye because he won't get the kind of paydays that make it worth his while.
But for now, Mosley is still in the game.
He's clinging desperately to hope and glory when it's time let go and move on to the next phase of his life.
