I saw this video late last night. It’s quite an incredible ability to have.
Sounds more like a curse. And, some things I certainly do not want to remember.
It would really, really suck.
I don't know about the average person but there are many things I am happy not to remember.
This is the mistake everyone makes; it's not an ability, it's a diagnosis. I even heard Rush refer to Ted Cruz as having an eidetic memory.
Actually, only children suffer from this and the report of an eidetic memory is delivered to the parents of an afflicted child with the exuberance reserved for terminal cancer or the like: "We're sorry Mrs. Jones to report your poor child has an eidetic memory." The victim, always a child, is destined to a miserable life ending in dementia by adolescence since the inevitable point will be reached where they will be unable to function at all as the entirety of their brain will be occupied by useless memories.
