A fascinating look at how the lungs work, lung disorders, treatments, and the importance of lung health. I loved that this book was written by a pulmonologist who offered insight into how pulmonologists go about diagnosing their patients. As an asthmatic I especially appreciated the steps one can take in order to preserve lung health. This book was very accessible to the average person so I never felt bogged down by medical jargon. This book was very well done.
