The 42-year-old Californian, known as AJ, has been dubbed Total Recall by scientists as she can picture where she was, what she did and what made the headlines on any date since 1976.
The woman - who claims her life is like a "running movie that never stops" - was tested with random dates and recalled big news events like Elvis Presley's death on August 16, 1977.
But she also knew minor news item dates like a local tax passed in 1978 and a plane crash in 1979.
Brain expert Professor James McGaugh - who tested AJ - called the condition hyperthymestic syndrome and noted she had obsessive qualities which help reinforce memories.
