Migraine pain can lessen from vomiting. Vomiting can cause dehydration. Dehydration can cause migraines.

偏頭痛可以通過嘔吐緩解。嘔吐會導致脱水。脱水會導致偏頭痛。

The human body is funny.

人體真的很搞笑。

I learned recently that ocular and retinal migraines are a thing. Thought I was going blind

我最近才知道原來眼睛的偏頭痛和視網膜的偏頭痛是同一個東西。我以為我要瞎了。

nightmarepoet

my trick is taking magnesium regularly, caffeine, a cold washcloth on your forehead in complete darkness and silence, and a nap

我的方法是經常攝入鎂，咖啡因，在完全黑暗和安靜的環境下往額頭上放一塊涼抹布，然後睡一覺。

Yes, before the pain of a migraine I get blind spots and it dots. I was trying to solve a sudoku and a number I placed kept disappearing I kept putting it back for it to only actually remove it. I realized what was happening rushed to some medicine and tried to fall asleep before the pain started.

沒錯，在偏頭痛發生之前我會有視野盲點，並且那裏會有小點點。我有一次在嘗試解開一道數獨，然後我放的一個數字一直在消失，我一直在把它放回去，但只是把它移除了。我意識到發生了什麼之後趕快去弄了一點藥，試着在偏頭痛開始之前讓自己入睡。

Headaches can be cured through resting and sleep. You can’t fall asleep because of your headache. Your headache gets worse because you’re thinking about it without having any other stimulus. Now your mild headache is double the intensity.

頭痛可以通過休息和睡眠治癒。但你會因為頭痛而睡不着覺。因為你沒有其他的刺激只能思考頭痛這件事，你的頭痛會變得更糟糕。現在你本來挺温和的頭痛一下子就就翻倍了。

Had a monster migraine last December, felt like absolute dogshit all morning. Took a migraine pill and about an hour later I threw up. The nausea disappeared instantly afterward and the headache was like 80% gone. I’ve never had that happen before.

去年十二月經歷了一次很猛的偏頭痛，一整個上午都感覺糟糕的要命。吃了一片管偏頭痛的藥，一小時之後我吐了。在吐完之後噁心的感覺立刻消失了，並且頭痛也消失了80%。在此之前我從來沒經歷過。

This is what happens to me most of the time I have a migraine. I read somewhere that sometimes your digestive system stops working during a migraine so anything you eat or drink is probably just sloshing around in there and the best way to reboot everything is to just be sick. That’s how it works for me, anyway. I really think migraines are very very individual.

我偏頭痛發作的時候就總是會發生這種事情。我在哪裏讀到説有的時候你的消化系統會在偏頭痛期間停止運行，於是你吃進去喝進去的東西基本上就一直在那裏堵着，重啓的最好辦法就是直接犯惡心。至少我是這樣的。我真的覺得偏頭痛是非常非常個人化的東西。

cherry_tiddy

It’s like headache/migraine pills that list “headache” as a sideffect.

就像一個把“頭痛”列為副作用的頭痛/偏頭痛藥片。

Viruses be like: “i am a bad guy, but that doesn’t mean i am a bad guy”

病毒：“我是個壞蛋，但這不意味着我是個壞蛋。”

WirelessTrees

How nice it could be to create an artificial virus that is able to produce the amino acids that we cannot produce ourselves, or the various vitamins that we cannot produce ourselves.

假如能製造一種人工的病毒，它能生產我們不能生產的那些氨基酸或者維生素該多好啊。

Double points if it uses our fat stores as a source for the energy required to create those necessary vitamins or proteins.

假如我們能用自己的脂肪作為生產這些必要維生素或蛋白質的能量來源，那就更好了。

Im not positive but I think CRISPR works kinda like that. I believe they use viruses to edit genes.

我不太確定，但我記得CRISPR（譯註：規律間隔成簇短迴文重複序列，一種可以對生物的DNA序列進行修剪、切斷、替換或添加的技術）就是這樣工作的。我記得他們是用病毒來編輯基因。

another_spiderman

You are correct. That is exactly what CRISPR is.

你説的沒錯。這正是CRISPR的作用。

Viruses are our Experimenters sending down software upxes or test code.

病毒就是我們的研發人員，在給我們發送軟件更新或是測試代碼。

I think different parts of the body have different pH values (yours might be for the bloodstream) but absolutely yes on changing pH with food, etc being B.S.

我記得身體的不同部分有不同的pH值（你的或許是血液中的），但確實沒錯，用食物之類的東西改變pH簡直就是扯淡。

Cruithne

If you squirt warm water into someone’s ear with a syringe, their eyes will automatically turn to the side that you squirted the water. If you use cold water, their eyes will automatically turn to the other side.

假如你用注射器往某人的耳朵裏噴射一股熱水，那麼他們的眼睛會自動地轉向被噴水的耳朵那一側。假如你用冷水，那麼他們的眼睛會自動轉向另一側。

This feels like some leftover debug code bullshit

這感覺就像是什麼被遺留下來的debug代碼。

How do I root my body? I want to install Linux on it.

我該怎麼root我的身體？我想給我的身體裝個Linux。

They actually use it to verify neurological function in severe brain damaged/stroke patients.

他們其實會用這種方法來給嚴重腦損傷/腦中風的患者檢驗神經功能。

Hey I can verify this, im an ICU nurse and we perform brain death testing by testing this reflex all the time :)

嘿我可以證明，我是個ICU的護士，我們一直都會通過測試這種反射來檢查患者是否腦死亡

not_thatkindofdoctor

Yea of all the wild stuff on here somehow this is the weirdest thing to me because I cannot fathom a reason for it.

沒錯，在這裏列出來的所有東西里面，某種意義上這是對我來説最詭異的東西，因為打死我也想不出來這究竟是什麼道理。

SolvingTheMosaic

The temperature difference between the water and the fluid in your balance organ makes that fluid move. You normally use this rotational information to lock your eyes in place when you move your head.

你射進去的水和你的平衡器官裏的液體之間的温度差，會導致那個液體流動。通常你在轉動頭部的時候，會利用這種液體轉動的信息來鎖定你的雙眼的位置。

flamingphoenix9834

Your brain continues to try to revive the body long after the heart has stopped. In some cases 30 hours later there has been found brain activity trying to make repairs to bring the body back. This is used to indicate time of death in murder victims.

在心臟停止跳動之後很長時間，你的大腦都會不斷嘗試復活你的身體。在某些情況下，在死亡30小時之後人們仍然會發現嘗試進行修補、讓身體重新正常運作的腦部活動。人們用這個來確定謀殺受害人的死亡時間。

‐-------------- EDIT: Upon research I should clarify, the brain survives after the heart stops for several minutes, however electroencephalomagnetic (EEG) brain activity continues for not only 30 hours but in some cases up to 72 hours after brain death. 

編輯：在研究之後我應該澄清一下，心臟停止跳動之後的幾分鐘內大腦還可以存活，然而通過腦電圖測量的腦部活動不僅可以延續至死後30小時，甚至在某些案例中可以延續到死後72小時。

This makes me very uncomfortable in an existential way.

在某種存在性的意義上這個知識讓我非常不舒服。

Some people have inner monologue. Some don’t.

有些人有內心獨白。有些人沒有。

He doesn’t have an internal monologue.

他就沒有內心獨白。

I do, and mine won’t shut up. It’s like a news ticker of my to-do list and my worries and conversations I need to have.

我有，並且我的根本停不下來。那就像是一個待辦事件列表的提醒，還有我擔心的事情，還有我需要進行的對話。

Prime example: touching a hot stovetop by accident and withdrawing your hand so fast that by the time you even feel the burn, the hand is far away

很好的例子：不小心碰到滾燙的煤氣灶之後，你收回自己的手的速度快到當你感到燙傷的時候，你的手已經撤開很遠了。

TexasPatrick

Humans are one of a few species of mammal that oddly don’t produce their own vitamin C due to lack of a certain enzyme. Other mammalian species who exhibit this mutation are those contained in the main primate suborder Haplorhinni (monkeys, apes, tarsiers), as well as bats, capybaras, and guinea pigs.

人類是哺乳動物中少數由於缺乏特定的酶而無法自行產生維生素C的動物之一。其他呈現出這種變異的哺乳動物是靈長類的主要亞目，類人猿亞目的成員（猴子，猿猴，眼鏡猴等等），以及蝙蝠，水豚和天竺鼠等。

All other mammals produce vitamin C in the liver.

其他所有哺乳動物都能在肝臟中製造維生素C。

People who live in “extreme” conditions for generations adapt in extreme ways. For example people that live in high elevations often have larger lungs and different blood makeup. Or my favorite is the Bajau people that live on the water and spend a lot of their time diving, their spleens have become 50% larger in order to store more blood.

那些幾代都生活在“極端”環境的人類會用極端的方式來適應環境。比如那些生活在高海拔地區的人們通常都有更大的肺和不同的血液成分。我最喜歡的是在水上生活的巴瑤族，他們的人生有大部分時間都在潛水，為了儲存更多的血液，他們的脾臟增大了50%。

When you get conditioned to physical activity, your circulatory system adapts -- more blood, more vessels, more blood cells. But your lungs really don’t. This is because no matter how much blood your heart is able to deliver to your lungs, the lungs still have no problem oxygenating it. This is why your oxygen saturation doesn’t drop during exercise (unless you have a heart defect.)

當你適應某種體育運動的時候，你的循環系統會做出相應的改變——血液更多，血管更多，血細胞更多。但你的肺卻真的不會發生變化。這是因為無論你的心臟能往肺裏輸送多少血液，你的肺都能毫無問題地向血液輸送氧氣。所以你的血氧濃度即使在鍛鍊期間也不會下降（除非你的心臟有缺陷）。

Is that why regardless of how much I exercise I can’t go up a flight of stairs without huffing and puffing?

是因為這個所以我無論做多少運動上樓梯都照樣會呼哧帶喘嗎？
