What we have by middle age is all sorts of connections and pathways that have been built up in our brain that help us. They know from studies that humans and animals do better if they have a little information about a situation before they encounter it. By middle age we’ve seen a lot. We’ve been there, done that. Our brains are primed to navigate the world better because they’ve been navigating the world better for longer.

There also are some other physical changes that they can see. We used to think we lost 30 percent of our brain cells as we age. But that’s not true. We keep them. That’s probably the most encouraging finding about the physical nature of our brain cells.
