Hey there! Welcome to Life Noggin.
大家好！欢迎来到脑洞大开的生命奇想。
In a world of smart cars and smart phones, just how smart is your body?
现在到处都是智能汽车和智能手机，你的身体有多智能呢？
While it might get a couple bad grades in the school of life, it turns out your bookworm of a body actually has quite the great GPA!
虽然在学校可能成绩不好，但是人体却有相当出色的平均绩点！
See, there are plenty of things that your body does for you without you even having to consciously think about.
看，你的身体为你做了很多事情，你甚至不用有意识地去思考。
From the moment you're born, your body knows that it has to breathe to receive oxygen and get rid of carbon dioxide.
从你出生的那一刻起，你的身体就知道要呼吸氧气，排出二氧化碳。
Your brain receives signals from your body telling it how much oxygen it needs, which is why you typically breathe slower when you're relaxed than when you're running to your computer on Monday mornings to get that sweet Life Noggin knowledge!
大脑会接收来自身体的信号，告诉它需要多少氧气，这就是为什么当你放松的时候，你的呼吸比周一早晨你跑到电脑前看节目获取知识时要慢。
Your body also has you unconsciously blink to keep your eyes moistened and help prevent foreign bodies from coming into your eyes.
身体也会让你无意识地眨眼，让眼睛湿润，防止异物进入眼睛。
It typically does this around 15 times a minute! That means it takes you about 12 minutes to blink 182 times… just an observation.
通常是每分钟15次。这意味着你眨眼182次需要12分钟，只是一点点观察结果。
So your body is smart enough to do a bunch of things for you, but it also urges you to do other things causing you to have certain feelings.
所以你的身体足够智能，可以为你做很多事情，但它也促使你做其他事情，让你有某些感觉。
Your body knows that you need to get energy in order to survive, so it releases ghrelin in the stomach that causes you to feel hungry.
你的身体知道想要生存你需要获得能量，所以它会在胃里释放胃饥饿素，让你感到饥饿。
Your hypothalamus, one of the sections of your brain, also plays a significant role in regulating your hunger, along with other things such as having you feel thirsty.
下丘脑是大脑的一部分，它的重要作用体现在调节饥饿感，还有其他方面，比如会让你感到口渴。
With the average person only being able to survive a few days without water and only a few weeks without food, I'd say your body is pretty smart to have you want to eat and drink.一般人只能在没有水的情况下生存几天，没有食物只有生存几周，人体是非常智能的，它会让你想要吃喝。
The hypothalamus also plays a part in regulating when you feel tired, which is super important too!
下丘脑也有调节疲劳感的作用，这也是非常重要的！
It's not just nature's way to charge your body like a cell phone. Sleeping is also vital to learning and retaining memories.
睡眠是自然给身体充电的一种方式，就像给手机充电一样，而且睡眠对学习和保持记忆也至关重要。
So if you want to be smart like your body, it's best to get a good amount of it!
所以，如果你想要像你的身体一样聪明，最好的办法就是多睡觉！
And fun fact, people tend to need less sleep as they get older.
有趣的是，随着年龄的增长，人们需要的睡眠越来越少。
So when you get old and retire, it's all late night video game sessions for you, buddy!
所以当你老了，退休了，就可以深夜玩游戏了，伙计！
On the subject of sleepy smartness, your body actually does a bunch of other important things for you while you sleep.
在睡觉的时候，身体会为你做一些其他重要的事情。
According to a recent study, it seems like your brain still processes information for you during that time.
根据最近的一项研究，你的大脑在那段时间里似乎仍然在处理信息。
The researchers found that participants could create sensory associations between sounds and smells during sleep, as well as re-activate associations that they had made previously.
研究人员发现，参与者可以在睡眠过程中将声音和气味联系起来，并重新激活他们之前所做的联想。
A different study found that your body may work harder while you sleep to clear out damaging waste products that build up in the brain.
另一项研究发现，当你睡觉时，你的身体可能会更努力地工作，以清除大脑中积聚的有害废物。
More than just a good student, your body cleans up after itself like a great roommate!
你的身体不仅仅是一个好学生，它还会像一个好室友一样保持自身清洁。
I still regret rooming with that slob Triangle Bob in college. See, your body is actually super smart!
我仍然后悔在大学里和那个邋遢的三角形鲍勃住在一起。看，你的身体真是超级聪明！
Sometimes we may overlook the little things like breathing and blinking, but it's all the small things that add up to making your body the smart, beautiful creation that it is!
有时候，我们可能会忽略一些小事，比如呼吸和眨眼，但这些都是让你的身体变得更聪明、更漂亮的小事情！
So what's your favorite thing that your body does for you? Or what do you wish it could do? Let me know in the comment section below!
那么，你最喜欢身体为你做什么？或者你希望它能做什么？请在评论区告诉我！
Quick reminder that we have another channel where we talk about the science behind your favorite video games.
提醒一下，我们还有另一个频道，在谈论你最喜欢的电子游戏背后的科学。
Have you ever wondered if we could travel faster than the speed of light? Let's explore the science of Mass Effect.
你有没有想过我们是否能比光速还快？让我们来探索质量效应。
The nearest star to our Sun, Proxima Centauri, is over 4 light years away, meaning light, the fastest thing in the universe, takes 4 years to reach it.
离太阳最近的恒星比邻星(Proxima Centauri)距离我们4光年远，这意味着宇宙中最快的光，需要4年才能到达它那里。
Our galaxy is over a hundred thousand light-years in diameter.
我们的星系直径超过10万光年。
If there are other intelligent races spread all across it, we better figure out some way to up the cosmic speed limit, if we're going to interact with them.
如果有其他的智能种族分布在它的各个角落，如果我们要和它们交流的话，我们最好想办法提高宇宙速度的极限。
As always, I'm Blocko and this has been Life Noggin. Don't forget to keep on thinking!
我是宝高，这里是脑洞大开的生命奇想。思考不要停！
