The former England striker has signed a 12-month deal with the Italians after leaving the Foxes over the summer.
At his presentation, one local reporter queried: "In Italy we are a little bit sceptical about players like you that are approaching their 40th birthday. We tend to say where's their motivation, how fit are they? What you say in response to these sceptics?"
Vardy responded: "You're one that I'll have to prove wrong. No, listen, for me age is just a number. As long as, I've always said it, my legs are still doing exactly what they used to and still feel as fresh as they do then I will carry on.
"At the moment there are no signs of them slowing down so I'll keep going and like I say I will be giving my all for this club."
Meanwhile, Vardy also remarked on the move: "Originally there was talk of it happening and obviously coming into a different country, its tough, so you have to make sure you have them conversations with my wife, my kids, loved ones because it is going to be a big change but one thing that happened was, thanks to technology, I was able to get on a zoom call with the manager.
"We spoke for 45 minutes to an hour, showing his passion for the club and how he is wanting to push on. And just looking in his eyes and what he wanted, that really resonated with myself and I think as a footballer, it is always nice to feel wanted."
Making it work
Vardy also explained, "It will just be slightly different until they (the children) get to come out here. The good thing is that kids aren’t at school at a weekend so we’ve already been looking at fixtures that especially the boys they want to come out and watch.
"So it will be things like that and me not getting to see them is not forever its possibly a week at a time. But like you say, FaceTime and stuff like that it works wonders. The kids are still buzzing that I’m saying goodnight every night and ringing them before I go to training and before they go to school.
"All in all its absolutely fine and like you say, my wife has been by my side and still here now. We are both missing the kids but its not forever and they’ll be out here soon."
