In the book, i make the argument that we do what feels like survival. Our brain is not the best brain to survive in the modern world. It's the best brain for usee ifi wo are good for us, so it's good for our ancestors. If something was good for the survival of our ancestors, the ancestors that were doing it survived more. I make the example of the human civilization going to mars. In a couple of generations there will be the first tume which is born on mars and his gens will still be adapted to live on hearth.
