Hyperkyphosis (a.k.a. Excessive Thoracic Kyphosis, “Dowager’s Hump”, or often just called Kyphosis) is an excessive outward curve of the thoracic (chest) region of the spine. There are many causes and contributors to this problem, but–for the purposes of this post–I’ll be focusing on postural kyphosis. There is a natural curvature in this part of the spine that is healthy. However, as is also true of the lumbar spine, the amount of curvature can become excessive, leading to a number of health conditions.
5.) Hyperkyphosis increases the risk of injurious falls in older people. Having one’s head forward, when combined with a lack of capacity to respond quickly to loss of balance, makes it more likely one will fall and hurt oneself.

4.) As far as the muscles of your upper back and neck are concerned, an 11 pound head can weigh 40 to 50 pounds when it’s forward positioned. Hyperkyphosis and forward head position tend to go hand in hand. If you purposely slump your back you’ll see why.

3.) There is reason to believe the young are becoming more prone to hyperkyphosis in conjunction with “text neck” from spending lots of time slumped over their phones.

2.) Yoga can help reduce hyperkyphosis. A test group who practiced hour-long sessions of yoga three days a week for 24 weeks showed an improvement in the flexicurve angle of kyphosis.

1.) Older individuals may be at risk for fractures, particularly when doing spine flexing movements, but careful use of spinal extensions (e.g. hands free cobra or superman shalabasana [locust]) can build strength and reduce fracture risk.

This book is a collection of transcripts of what are called dharma encounters, dokusan, or dharma combat. It’s a practice in Zen Buddhism involving a verbal interaction between student and teacher. Each of the twenty chapters takes a teaching of some past master of Zen (mostly Master Dogen), and explores it through these student-teacher interactions. The chapters begin with an introduction to the teaching at hand, conclude with a wrap up paragraph, and in between are an assortment of transcripts.
There’s a clear pro and con. Because information is presented in an unconventional format, there’s potential to gain insights that one might not otherwise. The students are trying to interact with the teacher in an unorthodox and outside-the-box manner. That’s part of the training. So as they relate the teachings to events in their own life or their own unique way of viewing the world, one gains access to those off angles of insight.
On the other hand, reading the transcripts can be repetitive as the teacher is trying to make sure that all students have some common understanding. It’s also not clear whether there was much selectivity in picking the encounters that were presented. Some readers might enjoy that it’s like being there at the monastery, but others might find reading the book a little bit like watching sausage making. While there are clever and insightful students, there are also individuals who seem to just be trying to get there turn over with, who appear to have no interest in the topic at hand, or who think some random action like a war-whoop will be evaluated as a deep and meaningful insight on the subject by the teacher (spoiler alert: it almost never is.) One should also not assume factual correctness in the student’s commentaries (e.g. at one point one of the students incorrectly identifies Vishnu as “the destroyer,” but [in Hindu mythology] Vishnu is the preserver / maintainer and it’s Shiva who is the destroyer. This error is of little consequence to the point being made, but the reader should be aware that the priority was to be faithful in conveying the transcripts rather than to accurately convey information.)
The organization seems sound enough. The book begins with rudimentary topics such as zazen (sitting meditation) and progresses into more philosophical and esoteric topics. As mentioned, there are twenty chapters, each built around a specific teaching and with the same organization. The only ancillary material besides the front matter (a Forward and an “Invitation to Dharma Encounter”) is a glossary (which is a worthy addition given the wide-ranging terminology in English, Japanese, Chinese, and Sanskrit, as well as the many names of individuals and documents that may be unfamiliar to the uninitiated.)
I enjoyed this book. As I say, it has its positives and negatives, but—on the whole—it was insightful and interesting. I’d recommend it for anyone interested in Zen, particularly anyone who intends to spend time at a monastery or meditation center.
