118 Power Up Your Mind

we need to speak to. We forget key details of a person’s face and feel
foolish when we cannot remember them. This kind of need is the

belief somehow that you can acquire a miracle cure or treatment to
improve your memory.
From time to time interesting articles appear about what is
going on in the brain. Recently, for example, most of the British

drivers: we all need to be able to do it. Managing knowledge effec-

least a basic understanding of how your memory works and what
you can do to avoid being the kind of person for whom things are
always “on the tip of their tongue.”

What is actually going on in your mind when you are using your

depending on the particular kind of experience. It seems likely that
