Remember how easy it was to pick up a new hobby, sport, or language when you were younger? Less fear of making mistakes, of feeling embarrassed, of asking for help. Turns out that people are ripe for learning at any age, it's never too late to learn a new skill. Brain plasticity—the strengthening and weakening of connections, and creation of new connections, that change how the brain is wired as we learn new things—is highest until about age 20, the years when the brain is developing. With age, we begin to balance the ability to acquire new knowledge with the ability to store what we have learned. But just because brain plasticity decreases as we age, doesn't mean that picking up a new skill is impossible. It just means that the way we approach learning the new skill should be altered. Read on to see the WSJ's take on learning at every age.
