● Adults who watch the screen for more than 6 hours a day are susceptible to depression
There is growing evidence that a sedentary computer and television lifestyle is an important risk factor for depression. A 2017 study showed a somewhat brutal finding: Adults who watch more than 6 hours of screen time a day are more likely to develop depression. This does coincide with another study's findings: Adults with long screen use have more sleep problems, which can affect their ability to cope with stress, leading to increased depression or anxiety.
The more developed modern technology is, the more massive information is gathered, the longer people's leisure time is occupied by watching movies, and while they are addicted, their bodies are also quietly being damaged, which seems to have become a major disease affecting people's health. Why not opt for a different pastime? Doing gymnastics with your family and cultivating a few more sports hobbies is beneficial to physical and mental health and can reduce the damage caused by the screen!

● On December 26, 2098, I shared a news item
What will News Network look like in 77 years? I heard that the first space base has been officially put into use, I heard that Mars can immigrate, and I heard that china can solve the problem of food and clothing for all mankind... It is believed that these visions will eventually be realized, and China's strength will be seen by the "whole universe".
All the past is the prologue; all the future can be expected. No matter how many tribulations we have experienced yesterday and how many achievements we have achieved, we are all for a better tomorrow. Only the people who have been humiliated know the importance of prosperity and strength; only a nation that has created glory can understand the meaning of rejuvenation. No matter how long it has been, the red gene in Chinese bones will never change.

● How to look at "Zhangbei data center uses cold air to cool down, saving 80,000 tons of standard coal per year", and what other energy-saving and carbon-reducing divine operations are there in life?
In the context of carbon peaking and carbon neutrality, the energy consumption of new infrastructure has also attracted more and more attention. Taking data centers as an example, there are currently more than 120,000 data center-related enterprises in China, and the number is increasing year by year, and 99% of the operating carbon emissions of data centers come from electricity use. Therefore, how to make the data center "green" has become the key to adjusting the power structure.
The country's "carbon peak" and "carbon neutrality" goals are precisely to cope with the big problem of global warming. It is a good idea to effectively reduce carbon from the "carbon emission reduction" technology of Internet technology, new energy power generation technology, and hydrogen production technology. We must also have this awareness, use less paper, use less disposable chopsticks, use less electricity, save a drop of water, and use these small things in life to play a role in carbon reduction.

● The US satellite approached twice, and the Chinese space station was urgently avoided
Recently, documents released on the website of the United Nations Committee on the Peaceful Uses of Outer Space show that the Chinese Permanent Mission to the United Nations submitted a note verbale to the Secretary-General of the United Nations on December 3, saying that this year, US satellites have approached the Chinese space station twice, threatening the safety of Chinese astronauts, and the Chinese space station has twice "emergency avoided collisions."
The note mentioned that in 2021, China's manned space project carried out 5 launch missions, successfully launching the space station Tianhe core module, Tianzhou-2 and Tianzhou-3 cargo spacecraft, Shenzhou XII and Shenzhou 13 manned spacecraft into orbit. The Chinese space station assembly is stable in a near-circular orbit with an altitude of nearly 390 kilometers, with an orbital inclination of about 41.5°.
During this period, the Starlink satellite launched by space exploration technology (SpaceX) has approached the Chinese space station twice. For safety reasons, the space station assembly implemented preventive collision avoidance control ("emergency collision avoidance") for the U.S. Starlink satellites on July 1 and October 21, respectively.
Since its inception, SpaceX's Starlink program has attracted a lot of attention, and one of the main reasons is that the total number of satellites it is expected to launch has reached a staggering 42,000. Under the Starlink program, a large number of satellites are sent into low Earth orbit, and the risk of collision is also increasing. The successful implementation of "emergency avoidance" also reminds us that being strong is the last word, and peaceful use of space requires the cultivation of internal skills.
