The definition of health experienced three times in the 20th century: 1948. Before that, many scholars thought that health was disease-free, which was the so-called "one-factor" definition of health. Although it has a certain guiding role in people's health practice, it is not very big. The World Health Organization (WHO) was founded in 1948, and the declaration clearly stated that health also includes mental factors. Some people call it the definition of "three elements" of health. Because this definition is comprehensive and effectively guides people's health care practice, in the next 40 years, the average life expectancy in the world has increased by about 30 years. In the 1990s, environmental pollution became more and more serious, so environmental factors were added to the definition of health, which became the definition of "four elements". After a short period of 10 years, the average life expectancy in the century has increased by about 10 years. It can be seen that health preservation needs the guidance of correct concepts.

At the end of the 20th century, more than 80 living Nobel Prize winners gathered in new york to discuss "What is the most important thing for mankind in the 2/kloc-0 century"?

For this problem, these human elites and wisdom stars all have the same conclusion: health!

What is health? Health is the foundation of everything; It is a deep root under lush foliage; Is the source of power for life and career! We can imagine that a patient who has been in bed for many years will not have a high quality of life; We can also imagine that it is difficult for a sick young man to climb to the top of his career; We can better imagine, said Zhang Haidi, who is in great pain, that the greatest happiness is the feeling when he dies! When you run out of money, you can still make money. "Pay back a thousand dollars when you run out." But what about health? Without health, what will we have?

So how can we become healthy?

Yes, how can I live healthily?

Think about it, what will accompany you in this life? Health, only health! Don't wait until health is gone to remember its importance!

Some people may say: I am still young and healthy, and I will be unhealthy one day.

Then, you should listen to the last words of the young scientist Hu Kexin: "If you give me another three years, I can finish this project with my comrades, and I will die without regret. Now is the time to need people. I shouldn't have left yet. I can't go. "

However, death didn't even give him a minute! 200 1 was only 38 years old when he died! Look at Jiang Zhuying, an excellent optical researcher. Before his death, people thought that Jiang Zhuying was an energetic and passionate person. 1982 June 14 Late at night, she was taken to the hospital because of unbearable abdominal pain, and died the next afternoon at the age of 43. Look at China mathematicians, Luo and Hong Chongwei, meteorologists Zeng Zaishun, electric power experts Chen Anle, ship experts Huayi, physicists Cai Shidong, Cui Changgeng, mechanics Zhuo Kecong, world religious scientists, linguists Yang Shunan and Liao, writers Lu Yao, Zhou Keqin, Mo, Shao, Zhu Xingyi, Yu Shusen and Wang Xiaobo. A large number of talented intellectuals died at the age of 50; Ma Hua, a fitness instructor, is the spokesperson of healthy image. Who would have thought that she died suddenly at a young age? It can be said that even she herself was unexpected!
