The world’s greatest tennis player Novak Djokovic is holed up in an immigration detention hotel in Melbourne that is famous for serving maggot-infested food and mouldy bread. The experience of being hauled through the coals for his beliefs may not, however, knock any sense into the Serbian who has been susceptible to all kinds of quackery in his life. He believes that his breathing trouble from gluten intolerance was solved by a quack who held slices of bread on his stomach and used kinesiological arm testing as a diagnostic tool. A great believer in alternative medicine, he once copied a page from Chinese traditional medicine that said – “Each organ in our bodies is undergoing repair in roughly this order: Lungs 3-5 am, Large intestine 5-7 am, Stomach 7-9 am…” The lover of nature and seeker after truth considers a Brazilian fig tree in the Fitzroy Park near Tennis Australia as his best friend in Australia. He once supported a quack on his Instagram Live Channel selling bottles of Advanced Brain Nutrients for $50 a bottle. It is curious that a professional athlete of his standing would believe in such mumbo-jumbo but not trust science enough to take a Covid vaccine that is doing so much for public health around a world beset by a coronavirus pandemic for more than two years now. “No vax, no entry” might be the verdict in his case.
