A must read for anyone who breathes air!
A fascinating book, informative and well written. Full of amazing info on the human body, especially all the parts involved in breathing. Gives a rundown on many many respiratory studies, clinical trials, methods, facts. Especially helpful for anyone with lung issues, but recommended for all. The amount of info packed into this volume may get daunting at times, but stick with it. It has set me on a path to better health.
