The 32-year-old Tottenham man is hoping to represent his country for the first time since Euro 2012 in the World Cup qualifier in San Marino on Friday night.
And, even after the withdrawal from the squad of Rio Ferdinand, Parker is one of a large contingent of over-30s, which also includes captain Steven Gerrard, Frank Lampard, Ashley Cole. Joleon Lescott and Michael Carrick.
But Parker says the performance of the 39-year-old Ryan Giggs for Manchester United against Real Madrid recently proves that the older brigade still have a huge amount to offer.
"I don't get the age one really," he said.
"People are too hell-bent on age, whether it's bringing players through or others being too old.
"If someone is good enough and playing at their best, you pick them.
"Maybe it's because I am 32, but I saw Ryan Giggs playing against Real Madrid in the Champions League. He was doing more running than anyone else.
"I do think there is a good blend and certainly a place for senior players with a young squad.
"We said it going into the Euros - that we have got a good blend of senior players and youngsters.
"I don't buy into the debate at all really. I just think that, if you are fit enough, and the manager feels you are good enough to do the job, you do it."
