Gennadiy Golovkin says he has no desire to retire despite approaching 40 on Friday.
The Kazakh middleweight hits the landmark age one day before he takes on Ryota Murata for the WBA and IBF titles.
Golovkin has been out of the ring for 16 months but is set to return on April 9 in a fight that has been rescheduled.
The bout with Murata was originally set to take place on December 29 but Covid-19 restrictions in Japan saw the fight postponed.
And GGG believes claims being older can give him 'an additional edge' going into his upcoming fight.
"There are advantages and drawbacks that come with age," Golovkin said. "I see all the changes as positive. I get smarter, I get more experienced and age gives me an additional edge.
"Time flies and the older you get the faster it goes. I continue to stick to my traditional training approach and when we get in the ring, we'll see the results.
"I wouldn't point out any particular goal that I'm still trying to achieve. I've achieved a lot and learned a lot during my career. I feel very comfortable in my current position.
"I've been in boxing pretty much throughout my entire life. I feel in top form and if there is demand, if there are interesting offers, you'll continue to see me in the ring."
A third bout against Saul 'Canelo' Alvarez, who is the only man to defeat Golovkin in his 43-fight professional career, has been mentioned by promoter Eddie Hearn.
The pair fought in 2017 and 2018. Many felt Golovkin got robbed in the first fight - which was scored as a draw - while others also believe GGG should have got his hand raised in the rematch rather than Canelo.
The Mexican has opened the door to a potential trilogy with Golovkin, claiming their rivalry is 'personal'.
Golovkin questioned his comments and asked why he decided to fight WBA regular light heavyweight champion Dmitry Bivol over him on May 7.
"I just like to get in the ring - against whom, this is secondary to me," Golovkin said.
"The comment that he's taking it personal, if he has some personal ambitions, he should have been looking for this fight to take place much earlier, not disappear, not go in different directions.
"Now to say that it's personal, I would say those sordid remarks are misplaced."
Golovkin's opponent is the underdog going into the contest but he holds something that GGG doesn't, and that's an Olympic gold medal.
Murata won the medal at London 2012 and has gone on to win 16 of his 18 fights, avenging both of his defeats against Hassan N'Dam and Rob Brant with stoppage victories.
Due to his achievements, Golovkin (41-1-1, 36KOs) is refusing to underestimate Murata - who is four years younger than him.
"It is going to be a top-class fight and of course this is the fight (that) warrants fans' attention, to say the least," Golovkin added.
"Both fighters are power-punchers, both fighters are dangerous and I would say it's totally unpredictable how it might play out."
