Let me tell you what's happening in my brain before I drink coffee.

Caffeine is the most popular psychoactive drug in the world.

咖啡因是世界上最受歡迎的精神活性藥物。

And the way most people get it is through coffee.

而大多數人獲得它的方式是通過咖啡。

When you drink the coffee, the caffeine actually hijacks your brain.

當你喝下咖啡的時候，咖啡因其實是劫持了你的大腦。

There are receptors in your brain meant for a chemical called Adenosine.

在你的大腦中，有一種叫腺苷的化學物質的受體。

And Adenosine is what actually makes you feel tired, but when you drink caffeine, the caffeine takes control of those receptors, and doesn't leave any room for the Adenosine, and that's why you feel alert.

而腺苷實際上是什麼 讓你覺得累， 但當你喝咖啡因， 咖啡因採取控制 這些受體， 並沒有留下任何空間 腺苷， 這就是為什麼你覺得警惕。

So, how many cups do you drink during the day?

那麼，你一天喝多少杯呢？

Let's see.

讓我看看

I would say on average, probably like, between five and eight.

You should be drinking no more than 400 milligrams.

你應該喝不超過400毫克。

Which is what, 400 cups?

那是什麼，400杯？

No, like depending on - cause each cup is different in terms of how much caffeine is in it,

不，就像取決於--因為每一杯的咖啡因含量不同。

-Okay -But...

-好吧，但是...

-Wait, I'm sorry, 400 milligrams of caffeine -Of caffeine.

-等一下，對不起，400毫克的咖啡因。

The FDA recommends no more than 400 milligrams of caffeine a day.

美國食品和藥物管理局建議每天攝入的咖啡因不超過400毫克。

There's about 142 milligrams of caffeine in this 12-fluid ounce coffee mug.

有大約142毫克的咖啡因在這12毫升盎司咖啡杯。

So, that's about three mugs a day.

所以，一天大概要喝三杯。

Okay, but so what if I have more than that?

好吧，但如果我有比這更多的錢呢？

One thing that I'm always worried about when drinking coffee, 'cause lots of times I'll be drinking, and I'll feel like my heart like just going like super-fast, and I automatically think, oh my god, I'm gonna die from drinking coffee.

有一件事，我總是擔心 當喝咖啡， "因為很多時候，我會喝， 我會覺得我的心臟像 只是去像超快， 我自動認為，哦，我的上帝，我會死 從喝咖啡。

Is it possible that I could actually drink so much coffee that I die?

難道我真的可以喝這麼多咖啡，以至於死掉嗎？

And how can I find out how much will kill me?

那我怎麼才能知道多少會死呢？

And, so I can drink just a little bit less.

而且，這樣我就可以少喝一點。

So, it's not necessarily drinking too much coffee that's gonna kill you.

所以，不一定喝太多咖啡就會死。

It's the caffeine in the coffee that's gonna kill you.

咖啡中的咖啡因會要了你的命。

There was a study that showed that if you drank 12 highly-caffeinated energy drinks within a few hours, you would most likely die.

有研究表明，如果你在幾個小時內喝下12種高咖啡因的能量飲料，你很可能會死亡。

So Joe, is that coffee filtered?

那麼喬，那是過濾的咖啡嗎？

It is.

它是。

That's actually healthier for you.

其實這樣對你更健康。

Haha, yeah!

哈哈，是啊！

Coffee contains over 1,000 compounds.

咖啡含有1000多種化合物。

Some of those compounds are healthy antioxidants, but there's something else in coffee that according to one study, can actually raise your cholesterol levels.

其中一些化合物是健康的抗氧化劑，但根據一項研究，咖啡中還有其他一些東西，實際上可以提高你的膽固醇水準。

But if you drink filtered coffee, the filtering process actually prevents those cholesterol-raising compounds from reaching your cup.

但如果你喝過濾咖啡，過濾過程實際上可以防止那些提高膽固醇的化合物到達你的杯子。

According to something I read online, caffeine affects your sleep, and you need a good like five hours to get it out of your system.

根據我在網上讀到的東西，咖啡因會影響你的睡眠，你需要5個小時才能把它排出體外。

It should be more like six hours.

應該是六小時以上。

Because the half-life of caffeine is about six hours.

因為咖啡因的半衰期約為6小時。

So, it'll take six hours for your body to metabolize 50 percent of the caffeine in there.

所以，你的身體需要六個小時才能代謝掉裡面50%的咖啡因。

So, basically then that means if you have a cup of coffee at 8 a.m., you're still gonna have 25 percent of the caffeine that was in that coffee in your system by 8 p.m.

所以，基本上就是說，如果你早上8點喝了一杯咖啡，到了晚上8點，你還是會有25%的咖啡因在你的身體裡。

So for the average viewer who's watching this and probably drinks coffee but not as much coffee as I drink, is coffee good for you or not?

所以對於正在看這個的普通觀眾來說，可能會喝咖啡，但沒有我喝的多，咖啡到底對你有沒有好處呢？

The overall consensus is yes.

總體的共識是肯定的。

Aha!

啊哈！

Hell yeah. Cancer-free, sharp brain, plenty of energy, terrible breath - sorry by the way.

地獄是的。無癌症，頭腦敏銳，精力充沛，口氣難聞--順便說一句，對不起。

We weren't supposed to - we didn't know we were gonna stand this close.
