Can we evolve so that we never have to sleep?

我们能否进化到永远不需要睡觉的程度？

First, we need to upgrade your body's reset system.

首先，我们需要升级你身体的重置系统。

When you sleep, your neurons pulse in a slow rhythm, reducing the noise in your brain and preserving what you learnt.

当你睡觉时，神经元会以缓慢的节律发放脉冲，减少大脑中的干扰信息，并巩固你学到的知识。

We need to fix that reset program so it runs

我们得修好那个重置程序，让它能正常运行。

while you're still awake by implanting electrodes across the entire brain cortex to reset one region at a time.

在你仍保持清醒的状态下，通过在整个大脑皮层植入电极，一次重置一个脑区。

Next, we need to get rid of your brain's toxic waste.

接下来，我们需要清除你大脑中的有毒代谢废物。

Protein byproducts that build up through the day are flushed out when you sleep.

白天累积的蛋白质副产物会在睡眠期间被排出体外。

The spaces between brain cells open up and fluid carries the toxins away.

脑细胞之间的间隙会打开，液体随之将毒素带走。

Without this, the proteins accumulate and you may get Alzheimer's.

如果没有这一机制，蛋白质就会堆积，进而可能引发阿尔茨海默病。

So each half of your brain will need to take it in turns to be cleaned while the other stays awake.

所以你的大脑两个半球需要轮流被清理，而另一个半球保持清醒。

But all this comes at a cost.

但这一切都是有代价的。

Your brain already burns around 20% of your body's energy.

你的大脑已经消耗了身体约20%的能量。

Keeping your brain running 24-7 would require around 3 times as much.

让大脑全天候运转所需的能量大约是原来的三倍。

And biologically, you are not human anymore.

从生物学角度来说，你已经不再是人类了。

You are closer to a bottlenose dolphin that can put half of its brain to sleep while the other half stays conscious.

你更接近宽吻海豚，它们可以让一半大脑进入睡眠状态，而另一半大脑保持清醒。

Nature hasn't found the perfect hack for zero sleep, but if we cram these fixes into a wearable sleep suit, you might be very hungry, but otherwise truly unstoppable.

大自然尚未找到完全无需睡眠的完美解决方案，但如果我们把这些修复机制整合进一套可穿戴睡眠服，你可能会饿得厉害，但除此之外，你将真的所向披靡。

什么是跟读法？

跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
