It's no secret that the constant grind of an 82-game regular season schedule, perennial playoff and international play during the summer have been catching up with San Antonio Spurs star Manu Ginobili.
As the Argentine plays out the last year of a three-year extension he signed back in 2010, he wonders whether this is the last hurrah with Coach Greg Popovich, teammates Tony Parker and Tim Duncan.
Ginobili, perhaps the best player to come out of Latin America, has won three NBA titles and a fourth could be in hand in what could be his ninth and final NBA season.
On days that he's feeling great, Ginobili says he feels like his engine can keep going. But on those nights when he's just achy after a tough battle, the feeling of whether it's time to hang up his sneakers creeps in.
The 35-year-old told Fox News Latino that at the beginning of the season his back "was hurting a lot" and he wasn't able to be in shape. "But now I'm feeling well without any pain," he says.
"When you're like that, your desire comes back and you feel good. If everything ended the way it does (today), I will tell you I'd keep playing. I'm not sure until when but I will keep on," he adds.
Ginobili is making $14.1 million this season and will become an unrestricted free-agent in the summer. But don't expect to see him in another uniform: before the season started he stated that if he was to come back for another year, it would be with San Antonio.
After accomplishing so much in the NBA and leading Argentina to a gold medal at the 2004 Athens Olympics, why would he want to continue to put his body through more wear and tear?
"I enjoy a lot what I do," Ginobili said.
The Spurs (27-10) are third in the Western Conference and hold a 2 1/2 game lead over Memphis in the Southwest division and it seems like Ginobili is ready for another run at The Finals.
"I'm just very fortunate to have been able to live off of this. I enjoy every game. As long as I'm healthy, I will keep going."
Ginobili has been averaging 12.7 points and 4.6 assists so far in 33 games this season, playing slightly over 24 minutes a game as Popovich keeps his team fresh for the playoff stretch run come April.
Over his last 10 games, he's stepped it up on the offensive end of the floor, posting up 14.8 points a game and 4.7 assists, shooting at a 48 percent clip.
The one thing that could draw Ginobili closer to retirement could be his twin boys, Dante and Nicola, whom will turn three years old in May.
Ginobli spent some time with them last season; he missed 22 games last season due to a broken bone in his left hand and spent a lot of time with them.
"It's always great being with your family. (But) you never want to miss time on the court. I had the advantage of being able to relax in my home," Ginobili said.
