10 'Bad' Habits That Are Actually Signs You're Smarter Than You Think

一身惡習(xí)肯定不利于身心健康和個(gè)人發(fā)展，但有點(diǎn)小毛病也未必是壞事兒。比如，研究證明，愛遲到的人往往比較樂觀，習(xí)慣做最好的打算；桌面凌亂的人可能更有目標(biāo)；偶爾走神可以提高工作效率等等。

擁有下面這些小毛病不僅無傷大雅，而且可能還對你有好處。

1. Procrastinating
拖延癥

There's a growing body of literature dedicated to why people procrastinate - and how to stop it.
關(guān)于拖延癥成因以及治療方法的研究文獻(xiàn)越來越多。

But Wharton professor Adam Grant argues that we should expand our conception of procrastination to include not just laziness, but also waiting for the right time. In other words, procrastination can help boost creativity because you give yourself a chance to develop your big idea.
但沃頓商學(xué)院教授亞當(dāng)?格蘭特認(rèn)為，我們應(yīng)該認(rèn)識到，拖延癥不僅僅是懶，也是在等待正確的時(shí)機(jī)。換句話說，拖延癥有助于提升人們的創(chuàng)造力，因?yàn)槟憬o了自己空間去想出好主意。

2. Biting your nails
啃指甲

Researchers followed about 1,000 kids starting when they were five years old. When the kids were five, seven, nine, and 11, the researchers asked their parents whether they bit their nails or sucked their thumb. About one-third of the kids displayed one or both habits.
研究人員們從5歲開始對約1000名兒童進(jìn)行了追蹤研究。當(dāng)孩子們處于5歲、7歲、9歲和11歲時(shí)，研究人員詢問這些孩子的父母，他們是否會咬指甲或嘬手指。約三分之一的兒童有至少其中一種習(xí)慣。

When the kids were 13 and then 32 years old, the researchers performed allergy tests. Sure enough, the group that had habitually bit their nails and/or sucked their thumb as kids were less likely to have developed allergies.
當(dāng)這些孩子長到13歲和32歲時(shí)，研究人員對他們進(jìn)行過敏測試。結(jié)果發(fā)現(xiàn)有咬指甲或（和）嘬手指習(xí)慣的孩子，更不容易過敏。

At the same time, one of the study authors advised parents not to encourage nail-biting or thumb-sucking in their kids.
與此同時(shí)，該論文作者建議父母們不要鼓勵(lì)孩子們咬指甲或者嘬手指。

While nail-biting doesn't typically cause long-term damage, it can damage the skin around the nail, making you more susceptible to infections. Meanwhile, if thumb-sucking continues past when a kid's permanent teeth come in, it can change how the teeth line up.
雖然咬指甲不會造成長期損傷，但會破壞指甲周圍的皮膚，讓人更容易感染。此外，在換牙之前嘬手指會影響牙齒的排列。
