1
Can we evolve so that we never have to sleep?
2
First, we need to upgrade your body's reset system.
3
When you sleep, your neurons pulse in a slow rhythm, reducing the noise in your brain and preserving what you learnt.
4
We need to fix that reset program so it runs
5
while you're still awake by implanting electrodes across the entire brain cortex to reset one region at a time.
6
Next, we need to get rid of your brain's toxic waste.
7
Protein byproducts that build up through the day are flushed out when you sleep.
8
The spaces between brain cells open up and fluid carries the toxins away.
9
Without this, the proteins accumulate and you may get Alzheimer's.
10
So each half of your brain will need to take it in turns to be cleaned while the other stays awake.
11
But all this comes at a cost.
12
Your brain already burns around 20% of your body's energy.
13
Keeping your brain running 24-7 would require around 3 times as much.
14
And biologically, you are not human anymore.
15
You are closer to a bottlenose dolphin that can put half of its brain to sleep while the other half stays conscious.
16
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.

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。
