John Blackett does something that no other 63 year old does in New Zealand. He plays club rugby every weekend for the Sumner Sharks.
"It's good fun - I guess when I can't do it I'll quit," he says.
John plays with players who are forty years younger, and even his son Kyle - who is 36 years his junior.
"It's like watching that big steam tractor come in from behind and push the whole group," says Kyle.
"He's always been a bit of a role model, and an icon for the team and the rugby club. Pretty entertaining, he's got a lot of passion behind him [and] loves getting amongst it for an old fella - you think he's 21 again."
John says by halftime, he is pretty shattered.
But despite that, he believes he could still be running around for the Sharks when he's 70.
