There are some useful information in this work and some genuinely interesting insights. Unfortunately there is also a lot of really bad quack science interspersed through out the book that I find really off putting. Two right off the top of my head are the idea that Westerners need to eat meat and consume alcohol, and that we normally only think with the left side of our brain.Further from it's obsession over the forebrain and brain stem et al to it's comments on the macrobiotic diet, the text is firmly rooted in the late 1970's making it dated at best.Combined with the reptition (how many times is the word "coffin" used throughout the text?) and the disjointed feel of the question and answer format, it is in my view just not a very good introduction.
