Thanks for the link, I didn&#x27;t know about this thing. Sacks&#x27;s book is actually (I think) somewhere on my desk gathering dust, I&#x27;ll need to get around to reading it.<p>Anyway, in my case it&#x27;s nowhere near that bad. I can recognize faces with <i>enough exposure</i>, but I have problems remembering them when first seeing, as well as enumerating features, imagining the faces and comparing them between each other. I can do all of that, but it takes a lot of effort and time.
