Most of us take our memories for granted. In this series you'll meet six people who don't have that luxury.
This feature visits a man who, following
an injury, makes up wild and wonderful stories, and believes them to be true - until disabused by his wife.
What's it like to doubt your own memory about your past and who you are - what it is like to live with such a fantasist - and what this case reveals about the accuracy of memory in general?
