my research librarian..................

      Another skill is the recall of names and facts.  By the time you are fifty, your brain is as crowded with information as the New York Public Library.  Meanwhile, your personal research librarian is creaky, slow, and easily distracted.  When you send him to get some information you need—say, someone's name—he takes a minute to stand up, stops for coffee, talks to an old friend in the periodicals, and then forgets where he was going in the first place.  Meanwhile, you are kicking yourself for forgetting something you have known for years.  When the librarian finally shows back up and says, "That guy's name is Mike," Mike is long gone and you are doing something else.
