At almost 102, Len Spence is one of Australia's oldest tennis players.
The Mildura resident steps onto the court twice a week for friendly round-robin games.
And while he is not as mobile on the court as he would have been when he began playing 90 years ago, Mr Spence takes every opportunity he can to one-up his opponents.
Other players from his social tennis group say his ability is a surprise.
"[Len's] strengths are perseverance, he just keeps chasing everything that comes his way," social tennis player Peter Crothers said.
"He is still very competitive."
But Mr Spence said the game was less about competition and more about social benefits.
He said the matches gave him a reason to leave the house and get moving.
"It is a family gathering," he said.
"We have been doing it for that many years that it has become a habit now.
"You go to tennis even if you don't play."
Inspiring others
The combined age of Mr Spence and those he shares the court with can some weeks equal 356, as several of them are into their 80s.
But no matter how tired or sore his opponents may get, they all know they can't quit until Mr Spence does.
Ross Douglass, one of the youngest regulars at the tennis gatherings, said Mr Spence kept the group and others motivated.
"He's a legend," the 71-year-old said.
"He's an inspiration actually to everybody, tennis players or not."
Mr Spence's daughter, Dee, said her dad had motivated her to play every week.
"I hadn't played for about 20 years, I reckon, and then one day Dad said: 'Why don't you come down and play with us? We could be short, so you could make up the numbers,'" she said.
"I wasn't contemplating playing tennis, but ever since I've been coming down with him, now probably eight or nine weeks, I'm looking into going back into competition."
Secret to old age
Mr Spence said luck helped him reach 101.
But with a history of long-living parents, it may have had something more to do with his genetics and way of life.
"My mum was 104 when she died and her mother was 100 before that," Mr Spence said.
"But I've never smoked and I never drank very much, so that helps."
Mr Spence said he enjoyed playing with his mates but it could soon be time to give up the game.
He said he probably only had about six months of tennis left in him, which would take him to after his 102nd birthday in early June.
"I'm not fit enough to do too much at the moment," he said.
But Mr Spence said he encouraged others to stick at it and practice because many who left the sport tended not to return.
