You shouldn't let your teeth go,otherwise you'll have to go to the dentist often when you are old. 你不应该不注意你的牙齿，否则，你老了的时候，就不得不常去看牙科医生。
And when you do, you'll fantasize that when you were young, prices were reasonable, politicians were noble and children respected their elders. 而当你老时，你会幻想，当你年轻时，价格是合理的，政客是高贵的，孩子们尊重他们的长辈。
