It depends on the person and their mental abilities. Where as intelligence is how well you learn, being smart refers to how much you know. With that in mind, the more you learn, the smarter you get, so the older you are the smarter you get. When you are old and may suffer memory problems, the knowledge is usually still there you just are having difficulty retrieving it. So generally, the older the smarter!
