Jenkins will be 35 by the time the World Cup comes to England in 2015 but is keen to still be involved as he adds to the 87 caps he currently holds for his country with the 2012 RBS 6 Nations looming large on the horizon.
He said: "In the back of my mind I want to play another World Cup.
"That obviously depends on the body, you just don't know how you're going to feel in a couple of years' time.
"But I enjoy playing international rugby and I would be very disappointed to lose that aspect of my life.
"It's a great buzz just to go out on the field and play for your country and I want to go on for as long as I can, for as long as I feel I'm doing a job at that level.
"Adam Jones is about the same age as me, and I know he will definitely be looking at another World Cup.
"Props in general, they have long careers, and there are more and more examples of people going on for longer at the top. Yet it does depend on the toll the game takes on your body because games these days are so physically intense.
"My two main targets are to go on another Lions tour and to make another World Cup."
