Very informative. Had to read it in small doses because of the processing needed to assimilate the information.

I was more interested in the creative part of the book which was why it was hard to read for me and keep my interest. Did not finish.

Gives some idea about how our bodies work but doesn't go into much details. Some mistakes in it kept me thinking if this guy is credible.
