Since the middle of the 20th century, more has been learnt about the ocean than during all preceding human history; at the same time, more has been lost.
It's hard to say, 'I don't believe in God.' I would love to know if God exists. But it's a very difficult thing for me to believe.
I don't really rate press conferences. It's not as though I leave the room fist-pumping my way down the corridor after a good one.
My worst days are still pretty good days. That's something I might lose in the moment sometimes, but I have a pretty good grasp of it.
Teeth actually turn out to be one of a couple of good sources of ancient DNA. The teeth, actually the enamel, is quite good at preserving the DNA, so it is a bit of time capsule so to speak.
There are a lot of good memories, and because I was injured, during the rehab, I met my wife. The tennis was very good but the injuries were good for something too.
I think one has to understand that there are stages in life, and that the life of an athlete has its limits. It's short, and then it stops, and sooner or later you have to accept that.
I think the tennis is only a game. You can lose. You can win. After that? In life, there are much more important things than tennis.
New Yorkers love it when you spill your guts out there. Spill your guts at Wimbledon and they make you stop and clean it up.
I live in jeans and T-shirts, and usually just throw stuff on over that. I love Brunello Cucielli, J.Crew for basics, NYDJ and DL1961 for jeans, and Magaschoni for sweaters.
Jean's whole job is to protect Victoria. Jean is a very practical, very orderly, very disciplined person; she is the personality called the gatekeeper.
I got bad calls every match, and I never got an apology. So I thought it was rather strange.
But, you know, I just want to play well and have fun playing well.
I mean, I feel like just a new person completely.
It wasn't my tennis that made me lose, it was a lot of different things going on, high drama, high emotion.
With everything else that would swirl around me when I got involved in it, tennis was my main concern.
It's about you. If you win, it's you; if you lose, it's you. Black and white. Nowhere to hide.
I like guys who wear nice clothes, nice jeans, nice trainers - I hate skinny jeans and those T-shirts that are really low-cut.
The British public like a Briton with personality, someone who comes out on court and isn't dour and down on themselves.
As a rule, wearing a bigger pair of jeans looks better than squishing yourself into a pair of jeans that used to fit before you gave up smoking.
Tennis is my life, obviously; I need to focus, I need to win. But it's not the only thing. I'm not going to play forever.
