Human beings are not born to exist forever. The oldest person on record is a French woman, Jenny Kalman, who died in 1997 at the age of 122. According to statistics, by 2040, the average life expectancy of Spaniards will surpass that of Japan and become the longest-lived country in the world, reaching about 86 years old.
However, there is considerable controversy about how long human beings can survive in the best environment. In 20 16, a group of scientists announced that the upper limit was 1 15. But last June, researchers conducted a survey on the mortality rate of the elderly in Italy, and the results showed that there may be no upper limit at all. In the past few decades, scientists have begun to understand that certain cellular and molecular processes can lead to aging. Researchers have found that aging cells secrete protein, lipids and other substances, which increase inflammation and tissue damage. In a study of mice, it was found that mouse cells were very sensitive to the combination of two drugs, namely dasatinib, an anticancer drug, and quercetin, a plant flavonoid. They improve the heart function and exercise ability of old mice, slow down the symptoms of osteoporosis and prolong the healthy old age.
If drugs can treat aging, is aging itself a disease?
Many studies show that we can prevent a series of age-related diseases, such as cardiovascular diseases and cancer, and ultimately affect the mortality rate.
Foreign epidemiologists say that many organs of human body (including brain) are not suitable for long-term use, and dementia, joint and hip joint problems and muscle mass will gradually appear with age. The upper limit of human life is about 85 years old. "
We'll all die. No serious scientist believes in immortality. We just want to prolong our life by maintaining a healthy old age.
