Many tennis players are young at heart.
Some feel the aging process is as soothing as heart burn.
Watch: Shot Clock, Towel Rack Coming to ATP
Andy Murray celebrated his 31st birthday on May 15th posting this image of himself wearing a funky birthday cake hat and a stoic expression with the wry caption "I love birthdays."
The two-time Wimbledon champion isn't the only player with an apparent aversion to birthdays.
At the 2017 US Open, Rafael Nadal was asked the best thing about being 19, which prompted the King of Clay to concede he longs for his teenage days.
"Best part of it, of course if I can come back to 19, I take it," Nadal said with a smile.
The three-time US Open champion said ever since he was a child, he's wanted to stay forever young.
"Of course, better be 19 than 31. My opinion," Nadal said. "I always wanted to be young. Even when I was 8 years old, I was not very happy to when I was, my birthday, to be 9. Still the same. I am 31, and I am not happy when my birthday going to be 32. I am happy being young, no?"
While Nadal turned back time becoming the oldest year-end No. 1 in ATP history last year, he joked he hasn't yet figured out how to stop time.
"I don't want to get older," Nadal said. "For the moment, I didn't find the way to stop that watch."
