Q. You mentioned the heat issues. Could you explain what feelings you go through when it starts to get to you? What actually happens?
NOVAK DJOKOVIC: Well, it's really hard to explain. Anybody who didn't play a professional level will not understand quite what's going on, but it's definitely not easy on the days where you have over 30 Celsius and court adds up another 10 degrees, or 15, and it gets really hot and it absorbs the heat, the hardcourts.So I'm not finding definitely no excuses, but everybody is different. I might react on the heat differently than somebody else, so you cannot compare myself to another player. You know, I might be faster than somebody for some reason. It's just genetics and nature, I guess....
Nobody can turn off the sun and just do me a favor, even though I would like it. (Laughter.)
Q. Back to the heat, are you working with your team on nutrition or types of fluids to drink or things to eat in between changeovers like that? Are you doing anything differently there to stave off...
NOVAK DJOKOVIC: Well, we're just waiting DHL to give us a canister of oxygen that I will put next to me on the changeovers so I'll breathe in. No. (Laughter.)
