There are people among us who have a remarkable superpower.  They never forget.  Literally, they can remember what they were doing on a specific day 10 years ago as easily as they remember a month ago.

This video from the New Scientist gives just a few examples of this superpower.  Amazing.

What would it mean for the world if everyone remembered in this level of detail?  Would we gain a new perspective on history and be nicer to everyone?  Or would we all sink into despair because we remembered the bad things as well as the good?
