Kevin Ganley may be about to turn 72, but he doesn't feel a day over 18.
That might be because he is about to officially hit that milestone birthday - on February 29.
Mr Ganley - affectionately known as "Spider" - has completed 72 laps around the sun, but due to being born during a leap year, he is only about to have his 18th official birthday on Saturday.
"In a couple of years my granddaughters will be the same age as me: 18," he said.
"Spider" was born in Port Pirie in 1948 and has been here ever since. After attending school, he worked at the smelter, then at a local building firm, then headed back to the smelter before retiring in 2012.
He married his wife Bernadette at Kimba, where she is from, on March 11, 1972, after meeting at a nurses' ball.
He played and coached football for Port and took part in cricket and golf, but now he gets to watch two of his granddaughters play hockey.
"It is so relaxed, such an easy lifestyle here," he said.
"Spider" said he had "never had any trouble" being born on a leap year, but it made for a good talking point.
Having celebrated the last big milestone of his 15th birthday when he was 60 means the party this time around will not be as big and he will enjoy dinner at his son's house with family. He toasted his 18th - the legal drinking age - with a beer.
