The 36-year-old former Wales captain believes the level of care afforded to the players at the club under boss Sam Allardyce's stewardship is second to none.
"Generally I still feel as fit as ever," he said.
"We have got a great staff here, they do things so professionally. If you buy into that you feel better and get the benefits from it.
"At my age I can use all the help I can get. I feel great, sharp and strong when I go out on to the pitch.
"I am sure I will know, Sam will know and everyone will know when the day to stop comes but that is not in my mind at the moment.
"There is a great spirit here and the backroom staff are certainly a massive part of the team especially at the moment where we have got lots of games."
