1. Heart Attack#

Yesterday, while browsing Twitter, I also saw Mr. Chen Hao's thoughts 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, similar to a power outage, causing significant 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 similar to a heart attack. It was already late at night, and Zeze hurriedly took me to the emergency room, fortunately with no major issues.

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 lesions. What is worrying is that the age of myocardial infarction in China is clearly decreasing. On the one hand, in the past, most coronary heart disease patients were elderly people in their seventies or eighties, and it was rare to see patients in their fifties. However, now it is not uncommon to see patients in their twenties and thirties, and it is very common to see patients in their forties and fifties 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. 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 smoking rates among women.
Secondly, heart attacks in young people are often caused by coronary artery spasms. Coronary angiography has shown that the coronary artery lesions in young heart attack patients are relatively mild.
Thirdly, once a heart attack occurs, the extent 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 we have 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 a major 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 steps. The first step is in the hands of the patients themselves and is also the most critical step. People with risk factors for heart attacks should immediately stop any activity and take 1 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 help immediately. The second step is for the emergency center to dispatch an ambulance quickly and transport the patient to a hospital with relevant treatment capabilities. The third step is for the patient to receive prompt diagnosis and treatment from the emergency department, cardiology department, and other relevant specialists within 90 minutes, aiming to achieve reperfusion therapy.

Health is the foundation of revolution, and I hope everyone can take good care of themselves and maintain physical and mental health.

2. Global Internet Users#

According to data provided by Tableau on Internet Use as of November 25, 2022, there are a total of 5.3 billion people using the internet worldwide, accounting for 66% of the global population. According to the latest data released by the United Nations on Population 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 27, 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 on PC#

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 up the registration trial for the AI chatbot Bard and 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:


Since ChatGPT will provide Plugin functionality to all ChatGPT Plus users this week, and Bard's additional features have not yet been released, it remains to be seen whether this conclusion will change significantly. 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 musical styles 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 have joined, 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.

6. Updates to Paid Columns#

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.
