What is football?
Rugby, a kind of ball games, is popular in Britain, America, Australia, Japan and other countries. Originated in rugby, England in 1823, it was originally named Rugby Football, or rugby for short. It is called rugby in China because it is spherical like an olive. Rugby is a city in the middle of England, where there is a Rugby School, which is the birthplace of rugby.
What are the advantages of playing football?
More effectively improve that function of the respiratory system.
Rugby is a combination of running and leg sports. In the process of running, passing the ball, shooting the ball, etc., the depth of breathing will be strengthened, so that more oxygen will be inhaled and more carbon dioxide will be discharged, so that the vital capacity will be increased and the lung function will be strengthened. This is because the main respiratory muscle groups (diaphragm, intercostal muscle, levator costalis muscle, upper and lower serratus muscle, etc.) and respiratory auxiliary muscle groups (scalene muscle, sternocleidomastoid muscle, pectoralis minor muscle, pectoralis major muscle, etc.) strengthen contraction, and promote the development of these muscles, thoracic expansion, chest cavity volume increase, alveoli develop well, respiratory strength increase, vital capacity, lung ventilation and suction (photo) Studies have pointed out that people who exercise regularly have strong physical adaptability, and their breathing appears stable, deep and even, and the frequency is also slow. When they are quiet, their breathing frequency is 7-11 times/minute, while those who do not exercise have a breathing frequency of 12-18 times/minute, and women are 2-3 times faster than men.
Prolong life more effectively.
A ten-year study shows that people who don’t exercise are 42% more likely to die young than those who often play football. 5%。 The reason is that if you don’t exercise, you will accelerate aging in many places, and even get old before you get old. And these people who don’t exercise have lower resistance to cancer, heart and so on than those who play football.
Strengthen the bones of the legs.
Rugby is the best exercise for training legs. In the process of continuous leg exercise, the blood supply of bone is improved due to the promotion of metabolism, and the morphological structure and function of bone have undergone good changes: the bone density is thickened, which makes the bone thicker, the arrangement of bone trabeculae is more orderly and regular according to different pressures and tensions, and the protrusions attached to muscles on the bone surface are more obvious. These changes make the bone stronger and stronger, thus improving the functions of bone in bending, bending, compression and torsion. Insisting on physical exercise can also enhance the strength around the joint, and the joint capsule and ligament are also thickened, thus increasing the stability of the joint; At the same time, physical exercise makes the joint capsule, ligament and muscles around the joint stretch, thus improving the flexibility of the joint.

Last night, the China men’s basketball team played a warm-up match in Italy and Cape Verde. Probably many people have never heard of Cape Verde, a tiny country in Africa with a population of less than 600,000, but it is a serious World Cup team, and there are also former NBA players like tavares (Cavaliers fans should have heard of it).
The men’s basketball team attached great importance to this game and warmed up on the sidelines very early. After the opponent hit 14-2 at the beginning and fell into a passive position, the men’s basketball team quickly adjusted and gave the opponent a wave of 15-1 to get back the advantage on the field, and kept it to the end.
This team in Cape Verde is similar to South Sudan, our opponent in the group stage. It relies on physical talent and three-point accuracy, and its tactical accomplishment is in a mess. We might have been afraid of such a team a few years ago, but now if we want to compete for physical advantage, we are not empty.
There are young new forces like Zhang Zhenlin and Cui Yongxi who can run and jump in our team. In the first half, Zhang Zhenlin’s breakthrough attempt broke the ground and almost succeeded. In the second half, it was Cui Yongxi’s turn to perform. First, he received Zhao Jiwei’s accurate pass and missed the dunk.
Then came a very amazing bottom line pull rod, turned around and took off against the defense, which was really confident and dared to do the action. The last quarter completely became Xiao Cui’s personal show, and the inside and outside flowers scored 10 points, and the men’s basketball team finally beat the opponent by 20 points.
In the whole game, Xiao Cui scored 18 points on 8-for-9 shooting and 2-for-3 shooting, with everything. Fans who stay up late to watch the ball should have such a feeling that everyone was sleepy in the second half, and Xiao Cui directly woke up a few goals in the second half. This boy is really fierce!
We have the physical talent. The biggest change of Old Joe’s men’s basketball team is the active sports ability and physical talent, at least in terms of hardware.Of course, the most amazing thing about the men’s basketball team last night was two words, fluency.
What was the most common picture we saw in the previous men’s basketball team? The defender dribbled the ball to wait for qi zhou to fall, shifted the ball to the front line at a 45-degree angle, then the front line dropped the ball to qi zhou, and then let qi zhou chisel hard. Is there a picture in his mind?
Of course, qi zhou and the defender will pick and roll, and finally qi zhou will handle the ball, lacking enough movement without the ball, and the attack will come to a standstill. Our previous inertia thinking was to rely on the inside height to revitalize the team. In fact, it has fallen far behind.
Old Joe’s national team, the biggest change is that more guards hold the ball and attack on the line, reducing the pressure of qi zhou’s holding the ball and letting qi zhou and other insiders eat cakes or score points in the second attack. The front line looks for opportunities to enter empty-cut, give full play to the physical qualities of people like Zhang Zhenlin and Xiao Cui, and play more on the basket.
In the past, we didn’t know what to do after the attack stopped. Now, once we stop the ball, someone will go up to cover it and look for opportunities in the other defense through some simple hand-to-hand cooperation.
The first goal in the opening game was qi zhou, whose inside line was empty when Zhao Rui passed the ball, and the latter scored easily. Of course, Zhao Rui didn’t play very well today. Today, he started, and the series was almost boring. Then in the second half, Old Joe let Zhao Jiwei start with Zhao Rui, which was much better.
Zhao Jiwei scored only 4 points today, but he had 9 assists at the same time. The positive and negative values were the highest +30. The reason why the men’s basketball team can play so smoothly is that Zhao Jiwei takes the lead, and his passing is the most comfortable. You can see that the empty catch for Xiao Cui is full of tacit understanding.
The men’s basketball team sent out 21 assists. Surprisingly, Fang Shuo had 4 assists. While serving as a nerve knife shooter, Fang Shuo could also pass some good balls, which was a pleasant surprise. Maybe Fang Chaoju will finally make the big list.
Old Joe, after all, is a famous European coach. He has brought a player of Jokic’s level and must have several brushes. We didn’t expect qi zhou to be a skinny version of Jokic, but we can expect Old Joe to bring more advanced basketball concepts to the men’s basketball team and make it more modern and smoother.
This is still the men’s basketball team without Li Kaier, and the next game will face Italy. Not surprisingly, Li Kaier will welcome his first show in the China men’s basketball team. If the reference value against Cape Verde is not great, then we can always see something against Italy in the next game.
Guoping needs attention! Malone had a lingering fear, calling it lucky to win, and praised the 19-year-old dark horse for its great progress. In the WTT Macau Championship in 2023, Wang Chuqin and Malone successively defeated their opponents in the semi-finals, successfully joined the men’s singles finals, and Guoping locked the championship and runner-up. After the game, Malone was full of praise for French 19-year-old Alex in an interview, calling himself lucky.
In the men’s singles semi-final, Wang Chuqin took the lead in playing against Japan’s core Zhang Benzhihe. Originally, everyone thought that the game would be fierce, but the actual situation was that Wang Chuqin easily defeated Zhang Benzhihe 4-0 and took the lead in advancing to the final.
Then Malone, the winner of the Grand Slam of Table Tennis, came out at the finale and played against Alex, a 19-year-old French teenager. This was their first match. Alex beat top seed Fan Zhendong in the previous match, so this match attracted a lot of attention. After the start of the game, Malone took the lead in 4-1, but then Alex tied 5-5, but Malone quickly stabilized the situation and won the first game with 11-8. In the second game, the competition between the two men in the first half was still fierce. When the score was 7-7, Malone made a mistake, and Alex scored 4 points and pulled back the game with 11-7. Alex led by 8-4, then Malone fired all the way, scored 7 points in a row, and won the game by 11-8. In the fifth game, Malone finished the reversal in the backward situation, and finally sealed the victory by 11-8, thus winning by 4-1.
After the game, Malone summed up the game in an interview. Malone’s first remark was that he was a little scared. Later, Malone said that Alex had made great progress in the past two years and his world ranking had also improved greatly. This was the first time to play against him, and I felt particularly great pressure, especially in the last two games, which were very difficult to win and finally won by luck. From Malone’s statement, it is not difficult to see that he was surprised by Alex’s performance. Perhaps he didn’t think that Alex could play like this before the game. Fortunately, Malone had rich experience in the competition and withstood the impact of Alex. Before Fan Zhendong was out of the game, he was probably not prepared. I hope the table tennis coaching staff can pay attention to Alex. In addition, Malone also talked about the final against Wang Chuqin. Malone said that he lost to Wang Chuqin several times last year, and this time he hoped that he could prepare in the best state.
Human beings’ longing for eternal life has a long history, and different cultures and religions have their longing and pursuit for eternal life. However, so far, whether human beings can live forever is still an unknown mystery. Starting with the problems of biological cells, genes and mechanical soaring, this paper discusses whether human beings can live forever and the possible ways to live forever.
1. Biological cells: Are there "immortal cells"?
The human body is composed of cells, and in the process of cell division, growth, aging and death, human beings are getting old, sick and dying. If we can find an "immortal cell", can human beings achieve eternal life?
In fact, no real "immortal cells" have been found yet. However, scientists have discovered a cell with certain "immortal" characteristics-cancer cells. Cancer cells can divide constantly and proliferate indefinitely, but at the same time, they will also destroy healthy tissues and organs, leading to cancer. Therefore, cancer cells are not an ideal way to realize human immortality.
In addition to cancer cells, some organisms also have certain "not old" characteristics. For example, turtles can live to be over 200 years old, and whales can live to be hundreds of years. However, even these creatures will eventually die, but they will live longer than other species.
2. Genes: Is there a "longevity gene"?
In recent years, the development of genetic science has led people to believe that the goal of human immortality may be achieved through gene repair and transformation. In fact, scientists have discovered some genes that may be related to longevity, such as SIRT1, FOXO, mTOR and so on. These genes are involved in important processes such as cell repair and metabolism, and are closely related to the length of life.
For example, scientists found through experiments that by activating SIRT1 gene, the life span of experimental animals can be extended by more than 30%. At the same time, researchers are constantly looking for other genes that may be related to life span, trying to extend human life span through gene editing technology.
However, genetic science is still in the exploratory stage, and the development of related technologies is also facing various difficulties. At the same time, gene editing and repair may also bring some unexpected consequences. Four, other possible ways
In addition to the possible ways mentioned above, there are also some other scientific technologies and theories that may have an impact on human beings’ realization of eternal life.
Stem cell technology
Stem cells are cells that can differentiate into many different cell types, and the development of stem cell technology is considered to be a field with great potential. Scientists are exploring how to use stem cell technology to repair and replace human organs and tissues, thus prolonging life.
The development of cloning technology is also considered as a possible way to achieve immortality. Through cloning technology, human beings can copy an identical individual, thus achieving the goal of eternal life. However, there are still many ethical and moral problems in this technology, such as whether it will lead to human beings becoming commodities and so on.
Artificial intelligence is a rapidly developing technology, and its potential has attracted people’s extensive attention. Through artificial intelligence, human beings can better understand their own life process and mechanism, discover new treatment methods and drugs, and thus prolong their life.
For example, artificial intelligence can help doctors predict the disease risk and treatment effect of patients more accurately, thus improving the treatment efficiency and success rate. At the same time, artificial intelligence can also help scientists analyze and understand life science data faster, thus accelerating the development of new drugs.
However, artificial intelligence technology is still in the stage of continuous development, and more research and exploration are needed.
Although the realization of immortality is still an unknown mystery, the continuous development and breakthrough of science and technology make us full of expectations and hopes for the future. From biological cells, genes, mechanical soaring, stem cell technology, cloning technology, artificial intelligence and many other fields, human beings have been looking for possible ways to live forever.
However, we also need to maintain a cautious and awe-inspiring attitude, and consider its possible impact and consequences while exploring and studying. We need to seriously think about how to balance scientific and technological progress and moral norms and find a suitable balance point. Only in this way can we explore better.
On March 11th, Beijing time, according to Ole newspaper, Messi has decided to renew his contract with Grand Paris and continue to play for the French giants next season. So, why is Mei Qiu Wang willing to stay?
Messi’s contract with Greater Paris expired this summer, and the two sides started contract renewal negotiations after the World Cup, but they were once deadlocked. However, according to the Argentine media, he has only negotiated with Grand Paris at present, and Dali is also the only club that offers Messi, so the two sides are expected to continue to work together.
"The only quotation" reminds people of Cristiano Ronaldo. Last summer, Cristiano Ronaldo wanted to leave Manchester United, and Mendes looked around for a big family, but he was repeatedly rejected. No Champions League team was willing to make an offer for him. Until the break with Manchester United last November, Cristiano Ronaldo’s situation was the same, and he could only leave Europe and go far to Saudi Arabia.
For Messi, it seems that no other team wants him. With his age and high salary, the Premier League may not be able to adapt. Serie A and Bundesliga can’t afford it. In La Liga, the only way is to return to Barcelona, but laporta is only speculating and has not made an offer.
However, unlike Cristiano Ronaldo, Messi has at least not fallen out with the club, so he can choose to stay in Paris and continue to play in the five major leagues in Europe. This is the first point.
Secondly, Messi still hopes to play in the Champions League and win the fifth Champions League title to tie the historical record maintained by Cristiano Ronaldo and Real Madrid. The last time he won the championship, it was already in 2015. This is the biggest regret left by Mei Qiuwang’s career, and he will try his best to complete it before leaving Europe.
Although Greater Paris has stopped in the top 16 for two consecutive seasons, Qataris are reluctant to let Mbappé go, and Neymar, who has a longer contract, may stay. If we continue to introduce reinforcements and strengthen the lineup this summer, it will undoubtedly be an important stage for the Champions League, and at least the French champion will be guaranteed, won’t it?
Third, Messi also hopes to participate in the 2024 America’s Cup and strive to lead Argentina to successfully defend its title. Cristiano Ronaldo has become a substitute in the World Cup, and his position and importance in the Portuguese national team have declined. The Five Shield Corps has changed its coach, so he can go to Saudi Arabia to "self-destruct" after winning the 2016 European Cup.
Messi is different. He is still the number one core in Argentina. Without him, the strength of the Pampas Eagle will be greatly reduced, and Scalogni will be there. Therefore, in the last competition of the national team’s career, we must go all out, and only by staying in Europe and staying in the giants can we maintain our current excellent state.
Therefore, in the absence of other better options, Messi is likely to be "forced" to renew his contract with Greater Paris, play at the Prince Park Stadium for at least another year, and then follow Cristiano Ronaldo and go to the United States, Saudi Arabia or other places to support the elderly.
