When are we going to die?

Why do people die? When are you going to die? The problem synagogues countless people. People are afraid of death, because of the human instinct and the life of faith, but this can not change the inevitable end of death. Over time, the years left a lot of traces in people, including our appearance, our body, and our thoughts without a reversible.

To investigate the natural limits of human life, the research team led by the geneticist Vijg of Einstein Medical School in the United States analyzed the "Human Mortality Database" in 38 countries and nearly 100 years. The study said that in 1920, the survival rate of the 85-year-old was the fastest, and the survival rate of the 90-year-old was the fastest in 1950, and the survival rate of the 99-year-old was the fastest in 1980, but it was slowly and slightly increased after the age of 99. This means that no one is likely to live through the age of 125. Scientists have made a statistical analysis of the trends in Anglo-American law Day, with the largest number of "super-people" (those aged over 110) in four countries.

The researchers then analyzed data from the International Longevity database and found that the maximum age of death reported in France, Japan, the United States and the United Kingdom (with the most supercentenarians countries) grew rapidly in the 70 's and early 90 's, But peaked in the mid-90 (mid-1990s), specifically 114.9 years old. VIJG's team concluded that the natural limit on human lifespan is about 115 years. Scientists say that a very small percentage of people will live longer than this.

But not all scholars agree with the findings. Richard Farag, an expert on gerontology at the University of Brighton in the UK, points out that VIJG's research did not take into account the medical advances, an important factor affecting human longevity. Chad believes some animal experiments have shown that through genetic technology or dietary control, life expectancy can indeed be prolonged. "These measures may prolong the average life expectancy of humans, but do not contribute to prolonging the maximum lifespan," Vijg retorted. ”

Jana Carmans died in a nursing home in France on August 4, 1997. Calment, aged 122, set the highest human longevity record. It is said that her mind is still intact. According to the New York Times: Aima Moranoca, by November 27 this year, 117 years old, she eats at least two eggs a day, 90 years like this, she said she ate more than 100,000 eggs in a lifetime. and the 113-year-old and 111-year-old, respectively, Americans Adeltrap and Agnesfinton.

But in the end, they will all die, what is this for?

S. Jay Olishansky, a researcher at the University of Illinois in the United States, specializes in human aging and has a life expectancy model. This model counts factors such as living environment, diet, stress, medical condition, etc., which can predict or calculate the life expectancy of a particular age group in a given period, and can be tailored to a particular individual and life expectancy alone. "The increase in longevity," he argues, "will soon reach its limit if it has not reached its limit." In the 20th century, longevity was largely due to a reduction in infant mortality, which was a one-time acquisition.

University of California, Los Angeles--The latest evidence from scientists suggests that everyone has their own "internal clock", and that the process is inconsistent with the speed of others. "While a healthy lifestyle may help extend life expectancy, the human innate aging process will always bind us to the fate of our inability to escape death," said Steve Horvath, a Horvath scientist at UCLA. "They found that some people are doomed to die sooner than their peers, even if they are physically healthy." 5% of the testers had a faster aging rate, resulting in a 50% increase in their prevalence, and were prone to premature death.

As individuals and species grow older, cell metabolism slows, toxins remain more active, immune cell activity decreases, and cancer cells become more likely to clog. These are the causes of old death, but why do we grow old in our human generation, and our embryonic cells (offspring) do not grow old? This is because of our genes, and our genes determine when people age. In other words, I think immortality is not impossible if humans have mastered the genetic technology completely.
