经常看到不少人有这样的感慨： 记忆力变差了，刚看到的东西一转头就忘记，很多简单的事情都记不住； 总觉得脑子里装满了杂乱的信息，昏昏沉沉的，没什么精力思考问题； 1. 分心 你是不是有这样的习惯：一边工作，一边查资料，一边在网上闲逛，可能还看几眼视频，刷刷社交媒 体，同时抽空看微信，回一下别人的消息…… 如果是的话，请注意：这个习惯，可能正在悄悄拖垮你的脑力。 为什么呢？很多人会以「多任务」为荣，得意于自己可以同时做好几件事情。但实际上，大脑是没办法 真正进行多任务的。你看起来在同时处理几件事情，其实只是快速不断地在它们之间来回切换而已。 比如你在写作过程中转头查资料，大脑实际上做的是：关闭写作的任务，清理掉残余的信息，切换到搜 索资料的状态，加载所需要的信息，规划接下来要做的步骤，把它们写入工作记忆，指挥身体去做出行 动…… 你每进行一次切换，这个过程都会重复一次。 明明看了很多东西，学了很多东西，但用的时候总是想不起来…… 有些人可能会觉得，是不是自己年纪上去了，大脑变笨了？但其实不一定。 我们生活中有一些司空见惯的小习惯，看上去没什么，但其实是大脑非常害怕的。它们会加重大脑的损 耗和负担，让大脑工作在运转 ...
