5. Chewing gum
嚼口香糖

It's rude to do it in a job interview, so don't. But when you're sitting alone, it could be a key to productivity and relaxation.
在面試時吃口香糖是一種無禮的行為，千萬不要這樣。不過如果你獨自待著，嚼口香糖是一種提高效率、放松心情的好辦法。

Multiple studies suggest that chewing gum helps you feel more alert - one study even found that people who chewed gum performed better on an intelligence test than people who didn't.
許多研究認為，嚼口香糖能讓你的思維更敏捷，甚至還有研究發(fā)現(xiàn)，嚼口香糖的人在智力測試中的表現(xiàn)會比沒有嚼口香糖的人更好。

Other research suggests that chewing gum boosts mood and reduces levels of the stress hormone cortisol.
也有研究認為，嚼口香糖能夠讓人心情舒暢，降低壓力荷爾蒙皮質(zhì)醇水平。

6. Keeping a messy desk
桌面凌亂

If piles of papers are toppling over onto your coworker's desk, it might be time to tidy up.
如果你的一堆文件已經(jīng)要倒向同事的辦公桌上了，那么可能是時候整理一下。

But assuming you can keep your mess to yourself, there could be benefits to the disorganization. Recent research suggests that messiness prompts people to be more goal-oriented because we're motivated to seek order somewhere.
但如果你沒有影響到別人，那么這種混亂可能對你有益。最近的研究表明，邋遢讓人更有目標，因為這促使我們在別的方面追求秩序。

In other words, simply the sight of a sloppy workspace could make you more productive.
換句話說，表面上看起來亂糟糟的工作空間會讓你效率更高。
