Jamie Murray wants to continue playing tennis into his forties so his daughter can witness her dad in action - but it's unlikely his brother Andy will enjoy the same longevity.
Jamie, 37, is aiming to win his eighth Grand Slam title at this year's Wimbledon championships. The Scot and playing partner Michael Venus will take on Hugo Nys and Jan Zielinski in a men's doubles round of 16 clash on Court 2 on Tuesday afternoon.
Jamie's daughter Ava was born last year and he'd love to continue playing until the youngster is old enough to remember watching her dad play at Grand Slam events. He believes he's fit enough to forget about hanging up his racket for the time being.
The double star's revelation comes after his brother Andy admitted he may have played his last Wimbledon match. The 36-year-old, who is a two-time men's singles champion at SW19, was knocked out by Stefanos Tsitsipas in the second round.
Jamie gave an insight into his retirement plans in his latest column for BBC Sport. He wrote: "I've no idea if I'll still be playing when Ava's old enough to absorb it more, but it would be nice to have her sitting at a match and enjoying it."
He added: "If I play until I'm 40 - which I think I can - kids still don't have a big attention span at the age of four. Her watching me play when she's older isn't necessarily what gives me the motivation to keep playing - it's more about me still feeling good and feeling fit."
Jamie insists his body is in "good health" and wants to improve. He also enjoys "the buzz" of playing in front of big crowds and has praised Wimbledon's "great atmosphere". The veteran also wants to appreciate playing before he's forced into retirement.
Yet Jamie is planning for life after tennis. He wants to move into the media and will work for Sky Sports at this year's US Open. He noted: "I don't know how much longer I will be able to play. Hopefully, that will be a few years away - I've no plans yet to retire."
Jamie has enjoyed a brilliant career, winning the men's doubles at the Australian Open and the US Open. He also won the mixed doubles at Wimbledon (twice) and the US Open (three times), and he was part of the British team that won the Davis Cup in 2015.
His brother Andy has also enjoyed a stunning career in singles, winning Wimbledon twice, the Olympics twice and the US Open in 2012. He's also reached the Australian Open final five times and the French Open final in 2016.

Unlike Jamie, Andy's career has been blighted by a major hip injury. He even underwent a hip resurfacing operation, in which the head of the femur (thigh bone) is covered with a metal cap. That should've ended his playing days, but he's fought on against the odds.
Yet Andy the end of his tennis career might be just around the corner. He said: "I don’t know [how long I'll go on for]. Motivation is obviously a big thing... It’s similar to last year. I had a long think about things, spoke to my family, and decided to keep on going.
"I don’t plan to stop right now. But this one [loss to Tsitsipas] will take a little while to get over. I’ll hopefully find the motivation again to keep training, keep pushing, try to keep getting better."
