This final section provides investment advice. In Chapter 10, we learn more about the origins of the lizard brain and why it costs us money. While our instincts may have helped our ancestors, we find that financial markets are the most unnatural setting for our brains.

Now in the final section we summarize all of the findings. We discover that the current situation is particularly dangerous-kryptonite for the lizard brain. And then finally we come to a surprising answer to the question of where to invest.
