Alright, so this next word is not slang and I'm not really sure most people know what this one means: prosopagnosia.

好，接下来这个单词不是俚语，我真得不太确定大多数人会知道这个词思：prosopagnosia（脸盲症）。

Someone suffering from prosopagnosia, for example, has serious difficulty recognising people by looking at their faces, but could still recognise them instantly from the sound of their voice.

例如，患有“面容失症”人很难通过观察面孔来识别他人，但仍能通过声音立即出对方。
