Like so many other anti-vaxxers, Djokovic is deep into so-called alternative medicine (SCAM).
An article in THE TELEGRAPH explains it quite clearly. Here are a few passages:
Here is an anti-scientific crank hiding in plain sight … [In his book Djokovic explains] how he suffered from recurring physical ailments – allergies, breathing difficulties, blocked sinuses – until he gave up gluten.
Nothing especially weird so far – until he explains how his gluten intolerance was diagnosed. A Serbian nutritionist called Dr Igor Cetojevic asked Djokovic to hold his right arm out at right angles and resist the pressure as he pushed down on it. Then the exercise was repeated, only this time while Djokovic held a slice of bread against his stomach. “I was noticeably weaker,” writes Djokovic, who adds that “kinesiological arm testing [has] long been used as a diagnostic tool by natural healers.” Yes, and mediums have long claimed to speak to the dead …
Here is a man who broke up his visits to Wimbledon with trips to the nearby Buddhapadipa Temple to meditate by a lake. A man who revealed two years ago that he has a “friend” in Melbourne’s Botanical Gardens – “a Brazilian fig tree that I like to climb”. Yes, Djokovic’s jet-setting spiritualism might sound charming in itself. But its side-effect has been credulousness.
Serve To Win [ND’s book] describes a so-called “researcher” taking two glasses of water and directing loving energy towards one, while swearing angrily at the other. “After a few days … [the angry glass] was tinted slightly green … the other glass was still bright and crystal clear”. Harmless, perhaps, if deeply dippy. But then, last year, Djokovic could be found hosting a former estate agent called Chervin Jafarieh on his Instagram Live channel. Jafarieh was selling bottles of Advanced Brain Nutrients at $50 apiece, which – like Djokovic’s resistance to the Covid vaccination – sounded contrary to the interests of public health…
… Djokovic expressed in a 2018 interview with Shortlist magazine. “I believe that it is our mission to reach a higher frequency through self-care by exploring and respecting our own avatar, our body and, by doing that, raising the vibration of the planet.” …
And so we return to the dark side of this whole peculiar tale. Were Djokovic just a journeyman player, his pseudo-scientific beliefs would be no more than a bizarre footnote. As it is, he is a powerful role model, particularly in the Balkans. Thousands of people have probably emulated his stance on vaccines. Some are likely to suffer consequences as a result…
Another article explains:
“Let’s not lose sight of how wildly anti-science Djokovic has publicly been for years,” Rothenberg began. “Here he was last year preaching about how you can change water with emotion.
“Naive, but maybe these real consequences today can be a reality check for his nonsense?”
Former New York Times reporter Steven Greenhouse said it was “sad to see such a brilliant tennis player join the anti-science, pro-poppycock anti-vaxxers”.
Tennis Channel producer David Kane added: “I sort of don’t care whether Australia bungled L’Affaire Novak because of political/media pressure. This is about someone who has been stridently anti-science and never indicated a good faith effort to receive this essentially mandatory vaccine.F around & find out, as they say.”
And a Guardian article provides further information:
His belief in alternative medicine is complemented by his commitment to alternative history. He frequently retreats to Visoko, in the hills of Bosnia and Herzegovina, where he meets up with the businessman Semir Osmanagic – whose claims that there are ancient man-made structures with magical healing powers, refuted by scientists, have turned the hills into a lucrative tourist destination. Djokovic has also expressed his support for the ultranationalist alternative historian Jovan Deretic, whose writings claim, among other things, that numerous European cultures, including ancient Greeks, Celts and Etruscans, are descended from Serbs.
I am quite confident that I play tennis as splendidly as Djokovic understands medicine. Yet, I do not pretend to be able to teach you how to do a perfect ‘top slice’. In contrast, Djokovic loves to take the role of ambassador for SCAM and other weird stuff.
His father stated that “Novak is the Spartacus of the new world who does not tolerate injustice, colonialism and hypocrisy but fights for the equality of all on this planet, regardless of skin color, religious belief and money they have.” Personally, I see this differently: Djokovic is badly affected by proctophasia; he tolerates no end of BS and fights for pseudoscience. And sadly, his views are all too persuasive to gullible consumers – not exactly what we need in a global health crisis!
