Every man's worst nightmare

Personally, I thought all of them already had it.

Give her any date, she said, and she could recall the day of the week, usually what the weather was like on that day, personal details of her life at that time, and major news events that occurred on that date. ... it became obvious that "the woman who can't forget" remembers trivial details as clearly as major events.
...
"Here's a woman who has very strong memories, but she has very strong memories of things for which I have no memory at all," McGaugh says.

Oh, I feel your pain.
