There are always people around us who will think of different ways to be lazy. Sometimes these methods are also very practical and have been imitated by people. On October 21, 2020, a student from Jiangxi Yi University shot a video that became popular on the Internet. He's a second year student. In the video he can be seen drinking efrom his bed with a long straw to drink water more easily.
This video has become popular on the Internet. Because he lives in the upper bunk, he can drink the water on the table without getting out of bed, which makes people think he is really lazy. But in reality, what he did was not simple, because the straw was very thin and there was a long distance between the table and the bed. Without high lung capacity, it would be impossible to suck up the water contained in the straw. The young man's ungrateful behavior also made netizens think it was really funny.
Because they are sports students, their lung capacity must be very strong compared to other people. In this way, you can be lazy in bed, drink water, and exercise your lung capacity, which makes people think that this guy is really strong. The young manalso responded, an action which allowed him to test his lung capacity. Actually, in life we always think of various actions to be lazy. In order to save our own actions, we do various things to help ourselves.
It can be said that although I was very lazy in action and put my own mental energy, it can also be said that it was not easy< /strong>. In our lives there are always these lazy things. For example, when you don't want to close the door, you can create a mechanism that can automatically open and close the door when people enter, making this very convenient for many people. .
Sometimes we don't want to get up and turn off the light, so we throw our slippers on the button. Although this method is lazy, it still requires a very high success rate. If you don't exercise regularlySurely, no matter how many slippers you put on, the lights won't go out.
