David Wallace will be 35 when the World Cup arrives in September but the Ireland flanker refuses to contemplate retirement.
Wallace will win his 68th cap in Sunday's RBS 6 Nations showdown with France at Aviva Stadium and continues to be a permanent fixture in the back row. The Lions openside, who is hoping to extend a contract with Munster that expires in June, believes his ability to perform at Test level is undiminished by age.
"I'm just as hungry as ever, if not more so," he said. "The closer you get to the end the more you relish it and the more you want to get everything you can from your career."
Wallace added: "I'm working as hard as I can. I hope I've got much longer at this level.
"There are so many permutations behind how much longer you can play for.
"Are you being selected, what do you have to fall back on? At the moment I'm really enjoying it.
"I feel like I'm in good shape and the body isn't giving out too much.
"I'm happy to keep playing. I'm happy with my form - my work-rate is as good as it's ever been.
"There are always things you want to tinker with and improve, but I'm happy with where I am at the moment.
"Fortunately no parts of my game have got worse with age. You gain more experience and knowledge and I hope that the curve is upward rather downward."
