There were nights as a semi-pro at Yeading when he did not get to bed after a match until 2am, had four hours' kip and was back on duty in the warehouse.
He told The Sun: "Yeah, I don't get that - it's baffling, especially with the life I've had.
"Honestly, I feel fit as a fiddle and we did a lot of running at Blackpool with the way we played. But you could start the season tomorrow and I'd be up for it.
"People say to relax and have family time now, which is great, but I just want next season to get going. Maybe it's because I came into the pro game late that I want to play non-stop.
"Honestly, you could throw me a ball and I'd be running round outside with it. I get the ball out on my holidays too. If somebody said I had to play tomorrow it would be no problem.
"When I was in non-league we had full-time jobs and still had loads of games and went training. Tiredness never entered my head, it still doesn't, I just want to play football.
"In fact I didn't think we played enough in the Premier League. In the Championship I was used to playing more often, because there were more teams in the League - it was always Saturday, Tuesday, Saturday."
