Extra Life (Young Readers Adaptation): The Astonishing Story of How We Doubled Our Lifespan

Gr 3-8--This adaptation of Johnson's adult nonfiction work explains the ways science and medicine have added years onto the lifespan of humans. Over eight chapters, with an introduction and conclusion, recommended reading, notes, bibliography, and index, this work reads like a research tool, breaking down history into developments that have had an impact on today's life experience. Johnson includes medical interventions, such as vaccines, antibiotics, drug testing, and pasteurization, as well as public service interventions, such as public health data, social epidemiology, the addressing of hunger as an issue, and car safety. The work is written in a formal tone. With additional resources provided in the back matter, there are opportunities for young readers to pursue further research. VERDICT Johnson's book will well serve a nonfiction STEM collection for young readers.--Jessica Schriver
