This was a bit different than the usual psychological non-fiction that I read, in that the author had little to no self-experience to relate to any psychological subject, and being a journalist rather than a scientist had no knowledge in that manner on the subject. However, it was interesting to go along with his journey, myself being more similar to his knowledge than any of the other books I've read, such as Oliver Sacks, to not be completely astounded and baffled and amazed at what I was reading, but rather to understand where someone is coming from and to wonder what they themselves will discover and share over the course of the research and investigation.
It was interesting, since as I said, my background is also not at all science related, yet like the author I would also enjoy attempting such experiments and sending my spittle to labs for testing etc. and then to realize with the author how silly I would be to do such things when I have no idea how to even interpret the results at all.
I think the book really followed a difficult experiment, perhaps the brain or body didn't want to realize certain similarities, yet by the same hand was on a quest to enlighten itself about them. The brain is still a pretty mysterious organ, but to me this book did not really solve any aspect of it's mystery, but over the course of reading that didn't seem to disappoint me.
