Vijay Singh believes age is no hindrance to success after becoming the oldest winner of a World Golf Championship event at the weekend.
The 45-year-old holed a three-foot putt on the final hole to win the Bridgestone Invitational and says the victory has left him feeling 20 years younger.
It was the Fijian's 20th success since turning 40 and admits that his attitude towards fitness and the recent example set by 53-year-old Greg Norman prove that you can stay at the top for as long as you want.
"I always feel 10 years younger," Singh said. "Now I feel like 20 years younger.
"It shows that you can still play no matter what your age is. It's just a number.
"I just feel comfortable right now. I'm not worried about being 40 or 45 or even next year for that matter.
"I have a great trainer who's taken me to the next level, and I think he's done wonders for me. I've got to give all the kudos to him. I think he really took me through a difficult program and it's showing up now.
"As you get older, I guess you just have to work a little harder, and that's what he's done to me, and I just have to thank him a lot for that. That shows that if you're physically fit, you can play as long as you want to play.
"Look what Greg Norman did. He looks pretty much the same as he did when he was playing the tour. He's as fit as he ever was."
Singh goes into the final major of the season this week at Oakland Hills full of confidence following his performance as Firestone that saw him peppering the flagstick with some unerring iron play.
"It gives me a lot of confidence," added the two-time USPGA champion. "You know, I struck the ball really well, especially with my irons. Except for the second day, my driver was really good all week.
"It puts me in a really good frame of mind going into next week and the rest of the season.
"I was really confident, and although I hadn't won, I was confident I was going to win. I told everybody that knows me that it's just a matter of time, it's going to come.
"So I'm glad that it's happened so quickly. I mean, this was a six-week run, and I was geared up to win. I'm glad that it happened the first week out."
