• She can relate where she was, what she was doing, and what made the news on any of the days.
• Having a normal healthy memory isn't just about retaining the significant things.
• Far more important is being able to forget the insignificant occurrences.
• Initial tests indicated that the woman was able to correctly identify the dates of every Easter for 24 years, plus where she was and what she was doing on those dates.
• Generally, a memory is formed in three stages: first it is encoded, then stored, and later retrieved.
