Some time ago, the math teacher Tang Jiafeng's wake-up alarm was on fire again, "How can you sleep!?" Your age, your stage, sleeps!? A bit out of the ordinary???!!! "Teacher Tang is one of the four famous mathematics teachers recognized by the current examination and research community, and should be the same as the jianghu status of Teacher Chen Wendeng ten years ago." Of course, listening to the sonorous and powerful sound, you can still see In front of your eyes Teacher Tang's face full of anger and disappointment that hates iron and steel.
But, if you think about it, isn't it the final stage before you can fall asleep before the age of thirty? There is an old saying that goes like this, thirty years ago can not wake up, thirty years later can not sleep.
According to the "2021 Exercise and Sleep White Paper", more than 300 million people in the mainland currently have sleep disorders, some people are plagued by insomnia, want to sleep but can't sleep; some people stay up all night wearing the most expensive masks; and also gave birth to a new profession "sleeper".
According to the official definition of good sleep in the following figure,
I am also several substandard, there are also tried to put down the mobile phone early, but the brain is still working again; tried to count sheep, or use the so-called "breathing aid method" to keep breathing deeply, there is no use, even if the daytime exercise can make the body tired, but the consciousness is completely awake, really miss the days when you can sleep in the morning, or it is because you slept too much before, so there is no realization of what Teacher Tang said, "You only at your age, use your best to live your own appearance, you can really have a good sleep."
Ha ha! The truth is that no matter whether you try your best or not, you will still not be able to sleep when you can't sleep. Of course, chicken blood still has to be beaten, which determines how much size of the house you will have insomnia on how soft the mattress in the future...
So you will still hate iron not steel, just rely on hate, iron naturally will not become steel, many years ago, chemistry teachers told us: the difference between iron and steel is in the carbon content, steel is a general term for ferroalloys containing a small amount of carbon, so pig iron to become steel is mainly to reduce the carbon content, at high temperature with oxidant oxidation of excess carbon and other impurities, this process is called refining!
So, fiercely, "Nian Nian got up, you are going to go to Reese class!" 」 Mom, I haven't slept well yet. "That's because you slept too late at night!" "Mom, can I not go to class?" "No!" If you can't get up, you have to put out the tang god's wake-up alarm, "How can you sleep!?" What the hell is going on? I just felt incredible! ”
