Rebecca Sharrock, 25, from Brisbane (Australia) is among the 80 in the world who has a rare condition known as Highly Superior Autobiographical Memory (HSAM), whereby the individual remembers everything that has happened.
Sharrock can remember all that has happened in her life since she was 12 days old, even childhood memories are relived with the same emotions. She can recite the whole Harry Porter series by heart.
The condition, which is uniquely neurological and also referred to as Hyperthymesia, makes the sufferer to remember all life events, pains and emotions vividly.
Now Rebecca is helping researchers at the University of California (United States of America) to understand and know more about this condition in younger persons since earlier research was done on older people above 40.
