Do we remember only 3% of our lives? [discussion of memory and the "factoid"]

I caught an interview with her a couple years back. I can’t remember what medium- TV interview, podcast, I don’t know (I clearly don’t have HSAM). But I seem to remember it was a visual medium because the interviewer was quizzing her, asking questions like “what were you wearing on ‘X’ episode of Taxi on ‘Y’ day”? She would answer “I was wearing a blue dress” and I seem to remember they then showed the scene and sure enough, blue dress.

To remember everything like that- I don’t know if it would be a great or terrible thing.
