First the bad points: Did anyone proof read this book? It's littered with typos, grammatical errors, punctuation errors, sentences that don't make sense. There's a whole paragraph which has been repeated but with slightly different wording, so we are obviously reading a draft version. Also the humor is funny at first but gets a bit wearing after a while and sometimes does not help the narrative.
On the plus side it's a reasonably informative book on the workings of the mind/brain which is accessible to a layperson.
