About the book: year / When and by whom was it decided that physical activity is always good and beneficial for us? Instead of mindlessly accepting the current reigning cult of sports with its principle of “no pain - no gain,” the author of the book, Stephen Barrer, a practicing neurosurgeon, offers us other criteria - common sense and moderation. He knowledgeably and with good humor describes the most popular sports - running, yoga, alpine skiing, cycling, etc., presenting them from an unexpected side, namely from the point of view of injuries and harm that they can cause to our health.
