That sounds depressing. Isn’t there any mental upside to getting older?
Yes, there is, Professor Miller said. Older people tend to be more disciplined and diligent, he said, which can compensate for learning deficits. Based on their greater experience in the world, they are also very good at putting ideas and thoughts into categories — the very basis of knowledge and wisdom.
It’s true: “The older brain is a wiser brain,” he said. But it can also get into a rut because of its lack of plasticity.
