Hyperthymesia is a condition that gives a person an extraordinary ability to remember and recall all events from their lives. They tend to spend a lot of time thinking about their past and do this while simultaneously experiencing their lives in the present. Jill Price is a woman with Hyperthymesia who was studied for 6 hours from master list of questions from a historical almanac. In 2003 she was asked by researchers to list every date of Easter since 1980. Ten minutes later, Price had written down all of the 24 dates as well as what she was doing each of the days. The one date that she got wrong was off by only two days!
