From the Exploration chapter of Brain Rules:
Researchers have shown that some regions of the adult brain stay as malleable as a baby’s brain, so we can grow new connections, strengthen existing connections, and even create new neurons, allowing all of us to be lifelong learners.
I’m so glad this is true; I want to be a lifelong learner. According to Brain Rules, the way to do this is to continue exploring, being curious, asking questions, taking an interest in the world and how it works.
