Greg Rusedski has hinted that he could stay in tennis longer than expected after returning from his drugs nightmare "feeling 20 again".
Rusedski lines up in the doubles this weekend as Great Britain play Luxembourg in the Davis Cup.
"My body feels great and I'm hitting the ball as well if not better than before," he told Radio Five Live.

"It's been a horrible six months and maybe the break has done me some good.
"Physically and mentally I feel like I'm 20 again instead of 30!"
After he was exonerated of a doping offence last month, Rusedski said he believed he had two more Wimbledons left before retirement.
Now it seems he's aiming further into the future.
"I'm definitely feeling fresh and rejuvenated and I am looking forward to playing at least two more Wimbledons.
"I always thought I was going to be back on the tennis court.
"It was a long process and something I don't think I should have been put through but I said I was innocent from day one, I proved it and, now I'm back to the game, I love doing what I want to do."
Rusedski will make his return to the tour on 19 April at a Challenger event in Bermuda. He's joined a strong field which also includes Luis Horna and Fernando Verdasco.
After that he will attempt to qualify for the Masters Series event in Rome.
Having asked to join the ATP supplement task force, Rusedski is expected to be invited to their next meeting, scheduled for Hamburg the following week.
