I have a really acute eidetic memory where I can recall entire passages from books I've read years ago, including the page number they're on (though sometimes I've been off by a page or two). This also goes for being able to remember faces really well, even if I've only seen a face for a few seconds. I did a facial recognition test at a science museum in London and got all of them correct. So um, I guess if anyone needed a witness to a crime, I'd be great at giving detail for it.

I also have pretty rare eyes. One is blue, while the other is half-green, half-blue. Technically it's called sectoral heterochromia, and it's so uncommon that there's not even a percentage for how many people have it.
