The striker laughs as he tells me he still feels like he is SBOBET 21, but the fact is he is into his 30s and is one of the senior statesmen in an England squad that has been shorn by injuries of much of its experience.
If the new faces in the squad are thinking of turning to him for advice, though, Vardy says he will direct them to goalkeeper Joe Hart and defender Gary Cahill.
By the time Alan Shearer was the age Vardy is now, he had already played his last England match, retiring from internationals in 2000 to extend his club career.
But Shearer had been England captain, won the Golden Boot as top scorer at Euro 96 and played 63 times for his country.
Vardy was 28 before his debut, having started out in non-league football, has Euro 2016 as his only major international tournament experience and a total of 17 caps.
So it is little wonder that he says, going into friendlies against Germany and Brazil, the incentive of a place in the squad for next year's World Cup is SBOBET "massive".
And as for whether he would ever consider 'doing a Shearer' and retiring from international duty he tells me: "I don't think past tomorrow, to be honest.
"If I start thinking too far ahead, I'll forget something."
Watching him for BBC Radio 5 live at Stoke last weekend was a reminder of the relentless energy that he puts into his game.
"It's probably a good job I still feel 21. If I felt my age, I'd be a bit more tired with my legs," says Vardy, who will be SBOBET 31 in January.
His recovery strategy is to get as much relaxation at home as possible; "which doesn't always work, with the kids running riot," and to try to fit in a swimming pool session and use Leicester City's cryochamber, which speeds up the process.
