I became interested in this subject while reading an article in a nursing journal, and realized I had never heard of this practice.
This book explains in a non-judgemental way how some people use autoerotic asphyxiation as a means of sexual pleasure, and how, occasionally, it can lead to tragic death. Often the condition of the corpse has led authorities to believe the person either committed suicide or was tourtured and murdered when they actually died accidently.
The book explains clearly how this practice is carried out, and has several pictures (not pretty) to show the results of an accidental death.
The book also mentions how teens often engage in self passing out activities (classmates of mine did this in the 60's as a joke), and how the consequences can be deadly.
The book is written more as an explanation of this practice, and how it affects families, and how police and CSI personel would be wise to keep informed of this practice.
Although the pictures are graphic, this book would work well for a professional or for a curious lay person interested in this subject. In addition, persons practicing this would be wise to read this book in order to be informed of the hazards.
I felt my money was well spent, and would recommend it.
