My friend recommended this book and to be honest it wasn't high on my reading list. What's there to know about breathing? Half of me was right and half was wrong.
I was surprised to discover the importance of breath mechanics and effects it could have on our body. The author doesn't offer insights himself but references doctors and researches. Turns out there are people who dedicated their lives to breath research.
However I was right, the book is overblown by unnecessary author's stories. It's funny because it seems that's the only authors content contribution to the book. When removed, the book can be cut by at least half and it will be much better at the end. Hence 2 stars. Not for the topic but for the book itself.
I had to rush it for bookclub, so I finished whole book in 24 hours. I found book interesting and can recommend it. It goes well as audiobook. If you are reading it, skip/skim author's story telling to save you time.
