Dear Bodhisattvas, greetings.
The cover image of this issue was generated by Midjourney, with the prompt "Digital art, male tennis player, white tennis outfit, swinging the racket forward, clear tennis trajectory, simple lines and colors --ar 16:9".
The following is the main content of this issue, with an estimated reading time of about 5 minutes.
1. Heart Attack
Yesterday, while browsing Twitter, I came across Mr. Chen Hao's views on KPI management. Unexpectedly, this morning I received bad news. Although I am not part of the tech community, I still feel somewhat emotional.
Once an acute myocardial infarction occurs, the blood supply to the heart suddenly stops, causing great damage to the heart. If not treated promptly, it often means the loss of a life and the breaking of a family. Data shows that there are about 600,000 new cases of heart attacks in China each year, with a mortality rate of over 30%.

In the summer of 2021, I also experienced symptoms of a suspected heart attack. It was already late at night, and Zeze hurriedly took me to the emergency room, fortunately without any danger.
Later, I found some information about heart attacks on the website of the National Health Commission of China.
Frequent Sudden Deaths in Young People
Although there is currently no direct data indicating the proportion of sudden deaths caused by heart attacks in young people in China, it is certain that most sudden death patients have coronary heart disease or other coronary artery diseases. It is worrying that the age of myocardial infarction in China is clearly decreasing. On the one hand, in the past, most patients with coronary heart disease were elderly people in their seventies or eighties, and it was rare to see patients in their fifties. But now, patients in their twenties and thirties with coronary heart disease are not uncommon, and those in their forties and fifties are very common. On the other hand, there are also more and more young people with risk factors for heart attacks.
Characteristics of Heart Attacks in Young People
First of all, in terms of risk factors, smoking is a very important but often overlooked factor. The fine particles in smoke can damage blood vessels and the heart. A 15-year cohort study in France found that the main reason for the decrease in the incidence of heart attacks in men and the increase in the incidence in women is the significant increase in the smoking rate among women.
Secondly, heart attacks in young people are often caused by coronary artery spasms. Coronary angiography has found that the coronary artery lesions in young heart attack patients are relatively mild.
Thirdly, once a heart attack occurs, the degree of necrosis is often more thorough, causing greater damage to the hearts of young people and a higher recurrence rate. The hearts of older heart attack patients have already developed certain adaptive mechanisms under the long-term "invasion" of coronary artery lesions.
After an acute heart attack, the time for rescue is actually very short. Because the blood supply to the myocardium is interrupted, if it is not restored in time, the area of myocardial necrosis will gradually increase, which is also an important reason for the high mortality rate of heart attacks. Therefore, the National Health Commission advocates the "two 120 principles", which means that patients should call 120 or other emergency numbers in a timely manner, and doctors should complete the rescue treatment as soon as possible within 120 minutes.
Regarding the rescue of heart attacks, there are three key points. The first key point lies in the hands of the patients themselves, and it is also the most critical one. People with risk factors for heart attacks should immediately stop any activity and take one tablet of nitroglycerin under the tongue when they experience symptoms of a heart attack such as chest pain. Repeat the dosage every 5 minutes. If taking 3 tablets does not work, call for emergency assistance immediately. The second key point is the rapid dispatch of an ambulance by the emergency center to transport the patient to a hospital with relevant treatment capabilities. The third key point is the rapid diagnosis and treatment by emergency department, cardiology department, and other related specialists after the patient arrives at the hospital, striving to complete reperfusion treatment within 90 minutes.
Health is the foundation of revolution, and I hope everyone can take care of themselves and maintain physical and mental health.
2. Global Internet Users
According to the data provided by Tableau, as of November 25, 2022, there are a total of 5.3 billion internet users worldwide, accounting for 66% of the global population. According to the latest data released by the United Nations, as of November 15, 2022, the world's population has reached 8 billion. This means that there are still 2.72 billion people who have not accessed or used the internet.
This reminds me of what I mentioned on April 27th, that "what I thought was ordinary is unfamiliar to many people." Therefore, I am even more convinced that it is necessary to actively share in daily life.
3. Using Default Browser for WeChat Desktop Version
The macOS version of WeChat now automatically uses its own very inconvenient browser when clicking on web links, which is very annoying. Today, I saw Charles C. sharing a method that has been tested and proven to work.
Pressing ⌘ command + ⌥ option + ⌃ control + R in the WeChat interface opens the WeChat repair tool, and then select "Open links with default browser".
Another way is to hold down ⌘ command when clicking on a link, which will also open the link with the default browser, but this method is not very effective.
For the Windows version of WeChat, go to WeChat settings - General settings and check "Open links with default browser".
4. Google Bard and MusicLM
Google recently released its latest AI base engine, PaLM2, and also opened the registration trial for the AI chatbot Bard and the MusicLM, which can convert text descriptions into music.
Twitter user Moritz Kremb was the first to test Bard and MusicLM.
For a detailed comparison between Bard and ChatGPT in Chinese, you can refer to this tweet. Overall, Moritz Kremb's conclusion is shown in the table below:
| Aspect | Bard | ChatGPT |
|---|---|---|
| Fluency | Better | Good |
| Coherence | Better | Good |
| Consistency | Better | Good |
| Creativity | Better | Good |
| Factual Accuracy | Better | Good |
| Sensibleness | Better | Good |
| Safety | Better | Good |
Since ChatGPT will provide Plugin functionality to all ChatGPT Plus users this week, and Bard's additional features have not been released yet, it is unknown whether there will be significant changes to this conclusion in the future. Based on my own experience, Bard's corpus is much newer than ChatGPT's, and it can connect to the internet without using plugins. Combined with Google's powerful search engine, its future development is worth looking forward to.
As for the test of MusicLM, it is truly amazing. Eight different genres of music were generated, each with its own characteristics. You can visit my website to listen.
5. Midjourney QQ Channel Beta
The Midjourney CN beta channel will be open for joining every Monday and Friday at 6 PM. Once a certain number of people join, the entrance will be closed again. If you are interested, you can apply to join the channel during that time period by searching for Midjourney in the QQ channel.

7. Zen Teachings
I observe that the Tathagata does not come from the past, nor does he go to the future, and yet he does not stay in the present.
