Whenever we're in it, we tend to do or say some strange things. 

當我們陷入其中時，往往會做或說一些奇怪的事情。

Like Triangle Bob trying to impress his vegetarian date by wearing a broccoli costume.

就像 Triangle Bob 一樣，為了讓他吃素的約會對象滿意而穿了青花菜服裝。

Broccoli Bob, we gotta work on that wardrobe.

青花菜 Bob，我們得好好調整一下你的服裝。

But first, this video; cue the intro.

但先來看影片，播放片頭吧。

Hey, there; welcome to Life Noggin.

嗨，大家好，歡迎收看 Life Noggin。

Being in love can feel amazing, but with that good feeling can come a downside.

戀愛的感覺可以很美好，但隨著美好感覺而來的是個缺點。

A lot of people say love can make you stupid.

很多人都說愛情會讓人變笨。

Believe it or not, researchers have actually studied this.

信不信由你，研究人員實際上也研讀了這件事。

In one experiment, they evaluated the cognitive control of volunteers who recently began a romantic relationship.

在一個實驗中，他們評估了最近開始戀愛的志願者認知控制能力。

This study included 43 participants that were tasked with distinguishing between relevant and irrelevant information, which tested their ability to focus.

這項研究包括 43 名參與者，他們的任務是區分相關和不相關的資訊，這測試了他們的專注力。

The degree of their love was determined through a questionnaire.

他們愛情的程度則是透過問卷判定。

The researchers found that the more in love the volunteers were, the less focused they were, which means that their cognitive control was impaired.

研究人員發現，志願者愛得越深，他們的注意力就越不集中，這表示他們的認知控制能力受到損害。

The authors of the study theorized that this inability to focus is caused by the infatuation that takes place in the early stages of a relationship,

此項研究的作者認為，這種無法集中注意力的情況是由感情早期階段的迷戀所引起的，

when people can't stop thinking about their new partner.

這時的人們無法停止想到他們的新伴侶。

That's not much of a surprise, considering each stage of romantic love is associated with a surge of hormones.

考量到戀情的每一個階段都與賀爾蒙激增相關聯，那不算是太令人訝異的事。

These stages include: lust, which is driven by testosterone and estrogen; attraction, which is created by dopamine, serotonin, and norepinephrine; and attachment, which includes oxytocin and vasopressin.

這些階段包括：由睪丸激素和雌激素驅動的慾望、由多巴胺、5-羥色胺和去甲腎上腺素創造的吸引力，以及包括催產素和血管加壓素的依戀。

They're all here at this party and we're feeling great.

它們都一起參加了這場剩會，我們感覺好極了！

Nice moves, Q-bot; Greeg, what... what are you doing?

Q-bot 你的動作真漂亮！Greeg，你在做什麼？

Most of these hormones directly affect the brain and are responsible for the emotions involved in romantic love.

這些賀爾蒙大多會直接影響大腦，並負責戀愛中涉及的情感。

For instance, dopamine makes you feel giddy and euphoric, while oxytocin makes you feel cuddly.

舉例而言，多巴胺使你感到眩暈和興奮、催產素使你想要擁抱。

But the impact on your brain doesn't stop there.

但對你大腦的影響不止於此。

Studies have found that, in addition to activating the parts of your brain associated with those hormones,

研究發現，除了激活你大腦中與這些荷爾蒙有關的部分，

love can deactivate other important areas of the brain, like the ones you need to make good judgements.

愛可以使大腦其它重要區域失去活性，例如你仰賴做出良好判斷的區域。

This is the frontal cortex.

這是前額葉皮質。

And researchers have found that when volunteers were shown a picture of their partner, MRI scans of their brains revealed that this portion of the brain shut down.

研究人員發現，當向志願者展示他們伴侶的照片時，他們大腦的核磁共振掃描顯示這個區域會停止運作。

They also found deactivation in the amygdala, which regulates fear, and areas involved in negative emotions, including the frontal cortex, parietal cortex, and parts of the temporal lobe.

他們也發現調節恐懼的杏仁核和涉及消極情感、保括前額葉皮質、頂葉以及部分顳葉等區域都出現了失去活性的現象。

So, when you're in a relationship, you're basically a happy, fearless idiot, in a loving way, but that may be a good thing.

所以說，當你在戀愛時，以一種充滿愛的方式來說，你基本上是個快樂、無畏的白痴，但那可能是一件好事。

The authors of the study believe that by suspending rational judgment, people are more likely to get together and procreate, which is, ultimately, a win for the human species.

研究的作者認為，通過暫停理性判斷，人們更有可能聚集在一起並生育，這對人類來說最終是一個勝利。

I don't know what Q-bot and the gumball machine are gonna make, but I just hope they're happy.

我不知道 Q-bot 和那台口香糖機會創造出什麼，但我只希望他們開心。

But, of course, this could make you miss some major red flags, so, don't ignore your close friends or family if they point out some concerns.

但當然了，這可能使你忽視一些警訊，所以說，如果你親近的友人或家人提出一些顧慮，不要置之不理。

They may be able to help you see through those rose-colored glasses.

他們也許能夠幫助你看透你的過度美化。（譯註：rose-colored 可用來形容看事情的角度「過於樂觀的、太過美好的」）

Triangle Bob, you can't just paint all the red flags white; that's not how this works.

Triangle Bob，你不能只是把紅旗漆成白色的，不是這樣運作的。（譯註：red flag 直譯為「紅旗子」，表示「警訊」）

So, have you ever been in love?

那麼，你戀愛過嗎？

Do you think it makes you do some strange things? 

你認為它讓你做了奇怪的事情嗎？
