Extract from the Telegraph:
"Jill Price, 42, can remember every part of her life since she was 14 but considers her ability a curse as she cannot switch off.
She described her life as like a split-screen television, with one side showing what she is doing in the present, and the other showing the memories which she cannot hold back.
Every detail about every day since 1980 - what time she got up, who she met, what she did, even what she ate - is locked in her brain and can be released to come flooding back by common triggers like songs, smells or place names.
Mrs Price, a widow who is a school administrator, sometimes struggles to sleep because the vivid memories crowd her mind and stop her relaxing.
Her condition is so rare that scientists had to coin a term for her condition - hyperthymestic syndrome from the Greek thymesis, for remembering, and hyper, meaning well above normal.
For years she remained anonymous, referred to only by initials in scientific journals while experts at the University of California-Irvine tested her ability."
