Marci's memory

[-JKP-]

Someone "having lost his memory of nearly everything" does not sound like a problem limited to short term memory though.

...

I visited someone in a nursing home a couple of years ago. She didn't recognize me (or the people around her), tried to go into the wrong rooms, had no sense of what time of day it was, and needed constant supervision.

I had brought along a picture book of news events from her younger years, thinking she would enjoy it, but when I saw her state of mind, I almost didn't pull it out, but the minute I opened the book, she started pointing at the people in the pictures and giving long, detailed and correct explanations not only of the events in the photos, but anticipating what would be on the next page based on their chronological order.

There's no way to know how much Marci remembered, or how correctly, but the mind is a complex thing.
