With the improvement of living standards and medical technology, the average lifespan of humans had increased significantly. From the perspective of gene editing technology, for example, the gene editing technology for high blood sugar was gradually maturing. In the future, more and more diseases could be permanently overcome through gene editing, which was beneficial to the extension of human life. Moreover, humans had been adapting to the environment, evolving, and improving their medical standards. All these factors made it possible for humans to live longer. However, the modern fast-paced lifestyle, high-stress work environment, and unhealthy eating habits also brought many challenges to human health. Therefore, although there were many factors that indicated that human life expectancy was increasing, there were also some obstacles. The novel " Ten Years of Death " is equally exciting.

The new hair that grew after shaving might feel rougher, but it did not actually change the nature and growth rate of the hair. Therefore, girls would not shave their beards longer. However, it was important to note that shaving in women could cause skin irritation, parasitides, and other problems, and frequent shaving could make hair rougher. If a woman has too much facial hair, it may be a sign of an imbalance in hormone levels in the body or a manifestation of diseases such as polycystis ovaris syndrome. It is recommended to seek medical examination in time.

There was a debate about whether humans would live longer and longer in the future. On the one hand, according to historical data, the global average life expectancy had generally increased from about 31 years in 1900 to more than 73 years in 2020. The life expectancy of most countries and regions had been increasing over the past few decades. Some scientists had suggested that the average life expectancy of humans could reach 150 years, while others believed that the average life expectancy of people could reach at least 108 years by 2030. However, on the other hand, there were studies that showed that human life expectancy might be approaching its peak. A new study published by the University of Chicago in the journal Natural Agility found that the growth rate of human life expectancy was slowing down. Unless there was a revolutionary breakthrough in this century, the limit of human life expectancy would be close to 87 years old. There was even a view that living to 100 years old was more difficult than before, and living to 120 years old was considered a " pure fantasy." Because most of the root causes of death were aging itself, even if a major disease was conquered, the impact on the overall lifespan of humans was negligible.
