60 Minutes Australia:

Imagine being able to remember every minute detail of your life. You can recall what the weather was like, what you were reading or what you wore to the shops at any minute, any hour or any day stretching back decades. It sounds like some kind of parlour trick, but it’s actually a real and very rare medical phenomenon.

As someone who can’t remember what he had for lunch last week, this “ability” is fascinating to me.
