> the analogy that a young brain can easily learn things but it gets harder to learn things the older the person as the brain is full of information. I'm not sure this is true in general. Older people have rich semantic connections that, if they can leverage them, allow them to learn things quickly. But those connections can also work against them (e.g. learning to drive on the other side of the road you get to keep 90% of what you learned, but also battle against a strong, pre-learned bias).
