Carragher is now determined to carry on playing as long as possible.
"People always ask me and other players about the future but it's up to the manager, isn't it? The manager decides whether you get picked or not," he told LFC Weekly.
"If it got to a stage where I was hardly ever playing and I still felt I could do something, I'm not sure what I'd do.
"But I'd hate to leave here. I'd hate for my career to just fizzle out because I love playing football so much.
"I think I'm well worth my place at the moment and if I keep the levels that I've been reaching, I don't see why that should change.
"I think age is in people's heads really. If an older player has a bad game, sometimes he may look for an excuse. I don't feel that much different [to a few years ago]."
