I had an assistant who had an uncanny ability to recall patients' files and ID numbers, as well as many other medical details. I was truly appreciative of this and, if I had a coin to spare, I'd give it to them.
In brief, a condition characterized by excessive memory recall.
It's said that people remember everything they saw while they were awake - how strange!
The difference between these people (see: eidetic memory) is that the memories they store in their minds are only about their own lives; I encountered this person today, I felt quite down that day, I misplaced my shoes that day. Thus, they can recall and forget.
The condition of having a total recall of your life can seem appealing, but it comes with its own set of struggles. You become a walking encyclopedia, your mind a vast repository of memories.
