In the smoke, Lao Zhang slowly exhaled a puff of smoke rings, squinted his eyes and said, "Do you know? I'm 92 years old and haven't stopped smoking since I was 20. His grandson Xiao Li's eyes widened, and he asked incredulously: "Grandpa, haven't you always said that smoking is harmful to your health?" Why do you live so long? "
Lao Zhang smiled mysteriously and said: "A few days ago, I saw a news article saying that the research of the Chinese Academy of Sciences found that nicotine may delay aging, and long-term smoking may be the secret of longevity!" "
This news was like a bombshell, exploding in Xiao Li's circle of friends. Some people exclaim that this is a subversion of conventional wisdom, while others question whether this is another misleading finding. What is the truth? Let's walk into this controversial topic together.
The study by the Chinese Academy of Sciences was published in an internationally renowned journal and attracted widespread attention. The research team found that nicotine activates a protein called "silencing information regulator 2 homolog 1" (SIRT1), which is closely related to delaying aging.
"SIRT1 is known as the 'longevity gene' and plays an important role in regulating cellular metabolism, antioxidant and DNA repair. Our experiments have shown that the right amount of nicotine can significantly increase the activity of SIRT1, thereby delaying cell senescence. "
The discovery immediately sparked a lively discussion in the scientific community and among the general public. Proponents argue that this may explain why some long-term smokers live longer. Opponents warn that the many health risks posed by smoking should not be ignored.

In order to further understand this issue, the reporter interviewed a number of experts. Dr. Li, a well-known respiratory specialist in China, said: "Although the results of this study are interesting, we cannot ignore the huge health hazards of smoking. Cigarettes contain thousands of harmful substances, and long-term smoking can significantly increase the risk of lung cancer, cardiovascular disease, and other diseases. "
Professor Zhao, a nutrition expert, pointed out: "Nicotine does have some potential positive effects, such as improving concentration and reducing stress. But that doesn't mean it's safe to smoke. We should explore how to get the potential benefits of nicotine without smoking. "
Lao Zhang's story caught the attention of his family doctor, Dr. Chen. Dr. Chan decided to delve deeper into this question, and he consulted a large number of experts after reviewing the literature.
Dr Chan found that while nicotine may have some potential positive effects, the harms of smoking far outweigh the possible benefits:
1. Cancer risk: Smoking is the leading cause of lung cancer, but it also increases the risk of many other cancers.
2. Cardiovascular disease: Smoking can damage blood vessels and increase the risk of heart disease and stroke.
3. Respiratory diseases: Long-term smoking can lead to respiratory diseases such as chronic obstructive pulmonary disease (COPD).
4. Secondhand smoke hazards: Smoking not only harms the smoker himself, but also affects those around him.
Dr Chan also noted that although Lao Zhang lived to be 92 years old, it may be more due to factors such as his genetics, lifestyle and luck than smoking.
With this information, Dr. Chen found Lao Zhang and his grandson, Xiao Li. He patiently explained to them the results of the study and the pros and cons of smoking.
"Lao Zhang, it's really remarkable that you lived to be 92 years old, but that doesn't mean it's safe to smoke." "In fact, you may be one of the lucky few exceptions. Most long-term smokers experience a significant impact on their lifespan. "
Xiao Li interjected and asked, "Then should grandpa quit smoking?" "
Dr. Chan thought for a moment and replied, "Considering Mr. Zhang's age and long-term smoking habits, quitting smoking completely suddenly may bring some discomfort. I suggest that the amount of cigarette smoking can be reduced gradually, and we will keep a close eye on his health. "
After listening to this, Lao Zhang nodded thoughtfully. "I see," he said, "it looks like I've been risking my health for so many years." "
Dr Chan continues, "The research on how nicotine may slow down aging is interesting, but we shouldn't ignore the dangers of smoking. Future research directions are likely to focus on how to safely exploit the potential benefits of nicotine, rather than reaping these benefits through smoking. "
Xiao Li asked curiously: "Then is there any other safe way to delay aging?" "
Dr. Chan smiled and replied, "Absolutely!" Maintaining a healthy lifestyle is the key to slowing down aging. This includes:
1. Eat a balanced diet: Eat plenty of vegetables, fruits, whole grains, and high-quality protein.
2. Regular exercise: At least 150 minutes of moderate-intensity aerobic exercise per week.
3. Get enough sleep: Get 7-9 hours of quality sleep every day.
4. Stress management: Manage stress through meditation, yoga, and more.
5. Stay social: Maintain good social relationships with family and friends.
6. Keep learning: Keep your brain active and learn new skills.
These methods can not only help slow down aging, but also improve quality of life without the health risks associated with smoking. "
After listening to Dr. Chen's explanation, Lao Zhang and Xiao Li both fell into deep thought. Lao Zhang said: "It seems that I have to reconsider my lifestyle. Although I am older now, I am still responsible for my own health. "
Xiao Li said excitedly: "Great! Grandpa, let's practice these healthy lifestyles together! I can walk with you, teach you how to use your smartphone, and we can also learn new hobbies together. "
Lao Zhang looked at his grandson with satisfaction and nodded in agreement. From that day on, Lao Zhang began to gradually reduce the amount of cigarettes he smoked, increase his exercise time, learn to use smart devices, and even began to try cooking healthy food. Although it is not easy to change habits, with the support of his family, Lao Zhang's quality of life has improved significantly.
The results of scientific research often need to be interpreted with caution. While some substances may have unexpected effects, we cannot ignore the known health risks. Maintaining a healthy lifestyle, a balanced diet, moderate exercise, and maintaining a good mindset are the real "secrets to longevity".
Scientific research is a process of continuous exploration and revision. We should be open and critical, neither blindly believing nor denying it altogether. Only in this way can we find truly beneficial knowledge in the complex information and make informed choices about our health.
Regardless of age, it's never too late to start developing healthy lifestyle habits. Let's work together for a healthier, longer future!
