排队检查护照的经历并不轻松：检察官看看你的护照……看看你……再看看你的护照……再看看你，真是一种精神折磨 。但站在他们的角度，他们努力想要弄清楚你的脸是不是和那页纸上的缩略图中的一样，这可不是一项简单的任务 。

Turns out, bad sleep did lead to more wrong answers on a face-matching task. And study subjects suffering from insomnia, meaning poor sleep plus other symptoms like anxiety, scored badly, too, compared to well-rested subjects.
