With a human body often there are wonders. Any deviation from the accepted norm does not pass unnoticed. Hop-o'-my-thumbs, giants and sleep-walkers, live in our midst. Someone is subject to the hallucinations, someone not nearly can eat, many are sad from the lack of a sun. These metamorphoses always generated tall stories and myths, while science seriously did not take up their study. Гэвин Фрэнсис investigates of great vitality myths and explains their nature. He calls to the changes in the body of the patients, both long-awaited and undesirable, and explains why these metamorphoses are not casual and important for all humanity. All ideas an author supports cases from practice and stories from history of medicine, art, literature.
