It's an international business. You know the story about Solzhenitsyn's Ant. And I told Durk that story about the ant that gave up. After being pushed down into a coffee cup several hundred times, the ant ultimately gives up and never tries to get out again. And Durk said Solzhenitsyn is right.
Nature is very conservative.
Sea slugs need serotonin . And ants use phenylalanine . And taurine is used by every electrically excitable tissue in the animal kingdom. Nature coded for these aminos a long time ago. And so, Durk talked about how an ant, and other animals, can develop a sense of learned helplessness.
