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

偏头痛可以通过呕吐缓解。呕吐会导致脱水。脱水会导致偏头痛。

The human body is funny.

人体真的很搞笑。

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

我最近才知道原来眼睛的偏头痛和视网膜的偏头痛是同一个东西。我以为我要瞎了。

nightmarepoet

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

我的方法是经常摄入镁，咖啡因，在完全黑暗和安静的环境下往额头上放一块凉抹布，然后睡一觉。

tinherbell

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.

没错，在偏头痛发生之前我会有视野盲点，并且那里会有小点点。我有一次在尝试解开一道数独，然后我放的一个数字一直在消失，我一直在把它放回去，但只是把它移除了。我意识到发生了什么之后赶快去弄了一点药，试着在偏头痛开始之前让自己入睡。

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.

头痛可以通过休息和睡眠治愈。但你会因为头痛而睡不着觉。因为你没有其他的刺激只能思考头痛这件事，你的头痛会变得更糟糕。现在你本来挺温和的头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.

去年十二月经历了一次很猛的偏头痛，一整个上午都感觉糟糕的要命。吃了一片管偏头痛的药，一小时之后我吐了。在吐完之后恶心的感觉立刻消失了，并且头痛也消失了80%。在此之前我从来没经历过。

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.

我偏头痛发作的时候就总是会发生这种事情。我在哪里读到说有的时候你的消化系统会在偏头痛期间停止运行，于是你吃进去喝进去的东西基本上就一直在那里堵着，重启的最好办法就是直接犯恶心。至少我是这样的。我真的觉得偏头痛是非常非常个人化的东西。

cherry_tiddy

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

就像一个把“头痛”列为副作用的头痛/偏头痛药片。

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

病毒：“我是个坏蛋，但这不意味着我是个坏蛋。”

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.

假如能制造一种人工的病毒，它能生产我们不能生产的那些氨基酸或者维生素该多好啊。

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

假如我们能用自己的脂肪作为生产这些必要维生素或蛋白质的能量来源，那就更好了。

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

我不太确定，但我记得CRISPR（译注：规律间隔成簇短回文重复序列，一种可以对生物的DNA序列进行修剪、切断、替换或添加的技术）就是这样工作的。我记得他们是用病毒来编辑基因。

another_spiderman

You are correct. That is exactly what CRISPR is.

你说的没错。这正是CRISPR的作用。

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

病毒就是我们的研发人员，在给我们发送软件更新或是测试代码。

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.

我记得身体的不同部分有不同的pH值（你的或许是血液中的），但确实没错，用食物之类的东西改变pH简直就是扯淡。

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里喷射一股热水，那么他们的眼睛会自动地转向被喷水的耳朵那一侧。假如你用冷水，那么他们的眼睛会自动转向另一侧。

This feels like some leftover debug code bullshit

这感觉就像是什么被遗留下来的debug代码。

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

我该怎么root我的身体？我想给我的身体装个Linux。

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

他们其实会用这种方法来给严重脑损伤/脑中风的患者检验神经功能。

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

嘿我可以证明，我是个ICU的护士，我们一直都会通过测试这种反射来检查患者是否脑死亡

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.

没错，在这里列出来的所有东西里面，某种意义上这是对我来说最诡异的东西，因为打死我也想不出来这究竟是什么道理。

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.

你射进去的水和你的平衡器官里的液体之间的温度差，会导致那个液体流动。通常你在转动头部的时候，会利用这种液体转动的信息来锁定你的双眼的位置。

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.

在心脏停止跳动之后很长时间，你的大脑都会不断尝试复活你的身体。在某些情况下，在死亡30小时之后人们仍然会发现尝试进行修补、让身体重新正常运作的脑部活动。人们用这个来确定谋杀受害人的死亡时间。

‐-------------- 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. 

编辑：在研究之后我应该澄清一下，心脏停止跳动之后的几分钟内大脑还可以存活，然而通过脑电图测量的脑部活动不仅可以延续至死后30小时，甚至在某些案例中可以延续到死后72小时。

This makes me very uncomfortable in an existential way.

在某种存在性的意义上这个知识让我非常不舒服。

Some people have inner monologue. Some don’t.

有些人有内心独白。有些人没有。

He doesn’t have an internal monologue.

他就没有内心独白。

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，并且我的根本停不下来。那就像是一个待办事件列表的提醒，还有我担心的事情，还有我需要进行的对话。

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：不小心碰到滚烫的煤气灶之后，你收回自己的手的速度快到当你感到烫伤的时候，你的手已经撤开很远了。

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.

人类是哺乳动物中少数由于缺乏特定的酶而无法自行产生维生素C的动物之一。其他呈现出这种变异的哺乳动物是灵长类的主要亚目，类人猿亚目的成员（猴子，猿猴，眼镜猴等等），以及蝙蝠，水豚和天竺鼠等。

All other mammals produce vitamin C in the liver.

其他所有哺乳动物都能在肝脏中制造维生素C。

30% of body waste is excreted via skin

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.

那些几代都生活在“极端”环境的人类会用极端的方式来适应环境。比如那些生活在高海拔地区的人们通常都有更大的肺和不同的血液成分。我最喜欢的是在水上生活的巴瑶族，他们的人生有大部分时间都在潜水，为了储存更多的血液，他们的脾脏增大了50%。

grenudist

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.)

当你适应某种体育运动的时候，你的循环系统会做出相应的改变——血液更多，血管更多，血细胞更多。但你的肺却真的不会发生变化。这是因为无论你的心脏能往肺里输送多少血液，你的肺都能毫无问题地向血液输送氧气。所以你的血氧浓度即使在锻炼期间也不会下降（除非你的心脏有缺陷）。

EDIT: Thanks to the actual professional in the field, who I quote below:

编辑：感谢相关领域的专家补充，我引用一下：

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

是因为这个所以我无论做多少运动上楼梯都照样会呼哧带喘吗？
