Not Federer, who, despite his age and wage, despite never needing to work a day the rest of his life, is able to keep up with the rigors of time and travel and somehow maintain the hunger needed to compete with players nearly half his age.
But I think Berdych will have a good day and play Roger tough. "So I know it's going to be a huge challenge".
Victory was his in the 10th game when Berdych netted a weary forehand.
However, if Djokovic is part-in and part-out in the months, ahead then he should defend a portion of the ranking points he has to defend for the balance of the season. Cilic looks for his second career grand slam title and first since the 2014 US Open.
Cilic trails Federer 6-1 in head-to-head meetings and is level at 6-6 against Berdych. And, as Reuters notes, she's heading into the final "an almost unthinkable 17 years after her first" Wimbledon title.
It seems that completing the career Grand Slam came at great cost for the Serb.
Just when he turned 21, his coach and close friend from his formative years Peter Carter was killed in a car crash in South Africa.
It makes you wonder, which is more amazing - Federer's talent or temerity?

That is what tennis Majors and especially Wimbledon does-create stories. His dominance since 2011 to mid-2016 has dwarfed even those of Nadal's and Federer's in their respective primes, but the drop-off since he achieved the Career Slam by winning the 2016 French Open has been steep.
"It's just discussions I always have with my wife about the family, about my kids, is everybody happy on tour, are we happy to pack up and go on tour for five, six, seven weeks".
In truth, though, what's most important is this: Federer is still as capable as ever of beating everyone who stands in his way.
From the ponytailed whippersnapper who won Wimbledon in 2003 to the grand old master on the verge of being crowned the King of Centre Court, time has failed to take its toll of Roger Federer.
Federer had defeated 2010 runner-up Berdych 18 times in 24 matches before Friday and he was quickly in the ascendancy, breaking for 3-2.
And only Pete Sampras and William Renshaw (who played in the 1880s, back when a previous year's champion only needed to win one match to retain the title) also can boast of seven men's trophies at Wimbledon.
"I mean, I don't see anything that would indicate really Roger is getting older or anything like that", said Berdych, who wore sneakers with a silhouette of Djokovic's face on the tongue because his own usual shoes were uncomfortable. But he eventually succumbed to the rigours of his calling last year - initiated by that bizarre wrenching of his knee in a Melbourne hotel while turning on the bath water for one of his children - and he reluctantly endured the pain and consequences of surgery.
