Why you must wear a mask?
为什么必须戴口罩？
As
some of you know that I have chosen to spend some of my time doing the

you may already know that our 4 lb. brain controls everything we do and yet there
are no solid connections like a computer.
有些朋友知道我选择花不少时间来完成一个几乎不可能完成的任务，尝试研究大脑，并了解其工作原理。您们可能已经知道，我们4磅重的大脑控制着我们所做的一切，但是却没有像计算机这样有固定的线路连接。
