If so, that's great news for Australian football which is looking at a mass exodus of 2006 World Cup players after the World Cup in South Africa next year.

"As you get older, I think you become more professional. My life is based around football and family," Cahill told The Socceroo magazine.

"I help get the kids ready for school then I'm off to training at 8.30am. And that means I'm there 60-90 minutes before training starts.

"I get a massage, a bit of yoga or Pilates, some stretching, a warm-up and we're ready to train.

"And even after training the physio comes around. And in the evening I do some work after I've spent time with the kids bathing them and reading them stories.

"So I try mix family with football. It's the only thing that's in my life now. There's nothing else that I know or do because I've turned into a machine because basically I love what I do and I love who I share it with."

It's expected that the Socceroos will lose Mark Schwarzer, Lucas Neill, Scott Chipperfield, Harry Kewell, Mark Viduka and others from the current golden crop in the next year or so, leading to a national team in transition.

However, Cahill's optimism about his body holding up offers hope that this Socceroo talisman could be part of the green and gold campaign for the Brazil World Cup in 2014.

If so, the Everton midfielder would be 32 when the next World Cup qualifiers roll around and 34 in 2014.

There's no doubt his experience and class would be vital in ushering in a new era.

"The biggest thing I can say is that every morning when I wake up, I'm excited to train," Cahill added.

"And when I play I know I'm excited to play. And I know if I eat right, sleep right I can give myself every chance. I always want fans to see I'm producing on the football pitch.

"I'm 29 years old, I'm in my prime and loving. I've been here [at Everton] for five years and I've built a great rapport with the fans and the football club. I feel it's important to put back in what they've invested in me.

"The best thing about it is, I'm more passionate about it than ever. I've played more than 400 games in my career domestically and I've scored 100 or so goals and every year I try to make something special and just keep the Cahill brand going and keeping the name of Australia high up there.

"I want kids to know that this boy who's come from nothing has succeeded and am still the same person.

"And I know I can play till I'm really old, maybe around 40. Who knows?"
