Do you want to undergo a complete medical examination in just an hour? Still would! And then, in another hour, be cured of all the diseases found at once? Well, or not in an hour, but, say, in a month, but without any harmful chemicals? Of course yes! The desire is quite legitimate, especially if you remember the hours-long queues at clinics and the tedious running from office to office. Alas, there is no device that could be used for a complete examination and at the same time for treatment. And it is unlikely to be invented in the coming decades. And those who try to convince you otherwise - everyone who promises to cleanse the blood, aura, energy channels - are lying. This book by Alexei Vodovozov, a doctor and medical journalist, is dedicated to exposing numerous charlatan methods. Vividly, logically, convincingly and intelligibly, he talks about what modern medical diagnostics is and how quack methods differ from those that really work. “But why should I trust him?” – a skeptical reader may ask. And he will receive a comprehensive answer to this question in the book. You shouldn’t take anyone’s word for it – any statement needs to be checked and double-checked. For example, the way Alexey Vodovozov does it, who supports each of his thesis with a link to an authoritative source.
