Novak Djokovic :Why Tennis players curse and smash their rackets

World Number 1, Novak Djokovic, has revealed why he and other tennis players lose their cool on the court. He also voiced his opinion on allegations of doping.
In a recent interview, he revealed that losing his cool on the court was a strategy. He claims it helps him stay focused, and as a result achieve better results on the court.

'Mangling my racket and an odd swearword on the court is not something I am proud of and it shouldn't happen.But even my coaches have told me that it's sometimes better to let out all the anger inside you, because keeping it bottled would just eat you up in the long term.'
He also addressed the allegations by some that he enhances his performance on the court by doping.
 'I never once contemplated taking banned substances and I could never do such a thing because I have been brought up in a different manner.'
'The people around me would never mention or even think that I should consume something which would enable a quicker recovery after matches.'
'I owe a lot to my genes as my grandfather is 78 and is still able to play volleyball, but the crux of it is in various recovery techniques ranging from stretching out to ice-baths.'
