我们常说,“很多东西,人们只有在失去的时候才知道珍惜”。你一定想不到,唾液也是其中之一。如果一个人说话的时候唾沫横飞,一定会成为被嘲笑的对象,因此,为了交谈的礼貌,我们应该避免过多的口水。但是唾液的话题是绝对值得深入讨论的,根据最近的研究,稀松平常的唾液,其作用远远不止是润湿你的嘴唇那么简单。 We often say, “Many things, people only know to cherish when they are lost.” You must not think that saliva is one of them. If a person flies when he speaks, he will be the target of being ridiculed. Therefore, in order to be polite, we should avoid excessive saliva. But the topic of saliva is definitely worthy of in-depth discussion. According to recent research, saliva is not as simple as moistening your lips.
