Journalist James Nestor talks with Lynn on The Mountain Life about the importance of breath. There is nothing more essential to our health and well-being than breathing: take air in, let it out, repeat 25,000 times a day. Yet, as a species, humans have lost the ability to breathe correctly, with grave consequences. In his book, BREATH: The New Science of a Lost Art , Nestor travels the world to figure out what went wrong and how to fix it.
