Well in that case you have better memory than any human who has ever existed. Also they also have better memory than any human who is better existed.

So there is apparently 1,000 people out there who are freaks of nature and no one's noticed.

Come on dude it's literally impossible to remember 1,000 people's names, even if you had met even half of them. Which you haven't because you can't meet 1,000 people in any real sense, you can see 1,000 people in a stadium perhaps but you can't really interact with them in any meaningful way.

Just because it says there your friends on Facebook doesn't mean they actually are your friends. In that you know them and would attend their weddings.
