Habit is a terrible force! We are used to believing in what our ancestors believed in, following prejudices from many years ago, being afraid that our grandmother will scold us for neglecting her time-tested advice... Myths about health surround us everywhere, from the very first day of our life, and we must abandon such beliefs sometimes it’s not very easy! But we are modern people and should strive for knowledge proven by science! Therefore, Andrei Sazonov, in his book, again draws attention to the prejudices that are firmly rooted in our consciousness - and debunks those myths that are still considered the truth. Is it true that tuberculosis is a “disease of dampness and hunger”? Are breathing exercises really effective? Do you need to walk exactly ten thousand steps a day? About this and much more - professionally and reasonably!
