According to data released by the World Health Organization, the life expectancy of Chinese residents in 2019 was 76.1 years, ranking 53rd in the world. It is noteworthy that the average life expectancy for males was 74.6 years, while for females it was 77.6 years, resulting in a 3-year difference between male and female life expectancy. In the top-ranking country, Japan, the male life expectancy is 6.3 years lower than that of females.
Research indicates that the natural life expectancy of humans is approximately 8-10 times the age of onset of puberty; however, males reach puberty on average 1-2 years later than females. According to this theory, the average natural life expectancy for males should be 10-20 years longer than females. In reality, across various countries, male life expectancy is lower than that of females.
Some believe that the greater the degree of male chauvinism in a country or region, the larger this disparity becomes. This is because it leads to males having to bear heavier social responsibilities. Factors such as long-term smoking, alcohol consumption, staying up late, excessive fatigue, indulgence, and a higher proportion of males engaging in high-risk occupations contribute to this disparity.
In fact, the actual lifespan of the human body is a different concept from natural lifespan and is influenced by various factors. Besides a higher proportion of males engaging in high-risk occupations, the most significant factor impacting lifespan is lifestyle habits. Regarding dietary factors, the following four habits need to be corrected promptly:
