Simple ways to make you smarter every day

让你每天更聪明的简单方法

Go outside to breathe in fresh air

出去呼吸新鲜空气

Everyone has their own memories and that's because part of the front brain uses all five senses to create a mind map of all the places you've been.

每个人都有自己的记忆，这是因为大脑前部的一部分使用所有的五种感官来创建一个关于你去过的所有地方的思维导图。

So, next time you go to a new place or drive somewhere, lower the window and breathe the air there. Smelling and hearing will retain the air around you. These senses select information and send it to the brain for processing.

所以，下次你去一个新地方或开车去某个地方时，把车窗放下，呼吸一下那里的空气。嗅觉和听觉会保留你周围的空气。这些感官选择信息并将其发送到大脑进行处理。

【知识点讲解】
