It's like simulating earthquakes: we can over and over study a bubble, crash, bubble, crash. Then we can see mathematically if there's some regular pattern and what's going on in people's brains when prices are going up and before the crash is happening.

We see that hyperactivity and reward areas are important when the bubble's rising. People getting caught up in it. We also see areas involving mentalizing, which means thinking about other people: Who's buying? Who's selling? Do they know something? We see emotional areas before the crash that indicate a sense of uncertainty or dread.

Charles Darwin and I and you broke off from the family tree from chimpanzees about five million years ago. They're still our closest genetic kin. We share 98.8 percent of the genes. We share more genes with them than zebras do with horses. And we're also their closest cousin. They have more genetic relation to us than to gorillas.

I've found that in now having experienced what it's like to make records and just through growing up in general that you should be expressive about what's affecting you instead of trying to sing about a subject just for the sake of other people getting something from it.
