In his book, Dr. Moalem establishes that the relationship between humans and diseases is not always negative, and the diseases that may be taking lives in the present, may have saved lives in the past. Understanding the nature of diseases and how they may have been beneficial to humanity can provide future research potential, such as developing ways to limit bacterial access to iron in order to combat infections or learning new ways to deal with natural occurrences from animals. Hemochromatosis, diabetes, and favism may be harmful in the modern world, however these diseases have been beneficial in the past, and will continue to be beneficial in the future, as understanding them may result in new, advanced medical practices that can save
