Very interesting 64

Fight or flight ... our only alternative was long caveman, but evolution has led some of us to take a smart and beneficial conscience there is another solution.
Despite the very interesting ideas, I found from paragraphs a bit repetitive ... but even if the treated cases are alike, and there is that the field of action that changes, I found in the end it was not boring.
It's a book to read and reread to fully absorb its substance.
