Everyone is thinking and talking about breathing, oxygenation and respiratory particles these days. Breath Taking, an enlightening new book by Dr. Michael J. Stephen arrives just in time for a curious public who wants to educate themselves about the lungs in order to understand the effects of the SARS-Cov 2 virus pandemic. Over the past two decades Dr. Stephen, who has been on the front line caring for COVID-19 patients (and recovered from the virus himself), has studied advanced end-stage lung diseases and worked with patients at diverse locales, including a Massachusetts prison hospital and a pediatric HIV clinic in Cape Town, South Africa.
