Once I knew this stage was coming, interacting with these animals, especially the friendly ones, became poignant. Their time was so short. This discovery also made the puzzle of their large brains even more acute. What is the point of building a large nervous system if your life is over in a year or two? The machinery of intelligence is expensive, both to build and to run. The usefulness of learning, which large brains make possible, seems dependent on lifespan. What is the point of investing in a process of learning about the world if there is almost no time to put that information to use?
