Why do so many people die within a few years after the age of 70? Meet 4 kinds of performance, longevity or longevity

Everyone needs to experience birth, aging, illness and death. The transition from young to old may be a process of slow aging, but once some age groups pass, the human body will usher in a cliff-like aging. Many people find that the relatives around them have reached the peak of death after the age of 70. So why are people more likely to die after the age of 70?

1. Why does it feel that people die within a few years after the age of 70?

Why is 70 years old a lifespan? Researchers from the University of Cambridge in the United Kingdom published a study in Nature. Through whole genome sequencing and hematopoietic stem cell analysis of 10 subjects aged 0-81, they found that after the human body reached the age of 70, hematopoietic stem cells mutated It will change from quantitative to qualitative , and the source of blood cells will show a cliff-like decline, which will lead to decreased blood cells, increased risk of blood cancer, reduced regenerative ability, etc., resulting in a cliff-like aging.

The gradual loss of muscles and the gradual decline of the brain are all manifestations of human aging. According to the "Research Progress of Sarcopenia Syndrome", it is pointed out that after the age of 30, the human muscle will lose 1%-5% every year. After the age of 70, the muscles of the elderly women Strength drops by 50%-70%, and muscle loss of 40% is life-threatening. The Proceedings of the National Academy of Sciences pointed out that after the age of 35, the brain begins to decline, and the decline is more pronounced after the age of 45.

2. In line with 4 kinds of performance, you may belong to "longevity constitution"

Du Changwang, deputy chief physician of the Department of Neurosurgery of the First Affiliated Hospital of Xi'an Jiaotong University, pointed out that after the age of 60, if you have the following symptoms, you may have a longevity constitution.

1. Flexible legs

Flexible legs and feet represent healthy muscles and joints. In the process of walking, it can not only promote metabolism, but also enhance resistance.

2. Good appetite

With the increase of age, the body's metabolism and digestion capacity will decline, and the gastrointestinal function will also deteriorate. A good appetite proves that the stomach is healthy and the body can absorb more nutrients.

3. Good sleep quality

After the age of 60, if you sleep well, your body is generally better and you are more likely to live longer.

4, good lung capacity

Good lung capacity means that the respiratory system is healthier and the physical condition is relatively younger. Such people are also more likely to live longer.

3. Implementing a restrictive diet may prolong life

Researchers at the University of Texas Southwestern Medical Center published a study in Science that followed mice for four years and found that dietary restriction may extend lifespan.

Previously, Harvard University also published a study in "Cell", pointing out that intermittent fasting helps protect mitochondria and keep cells young, thereby slowing the aging process and prolonging lifespan.

Internationally, "light fasting" is more popular, mainly including the 16:8 fasting method and the 5:2 fasting method. The 16:8 fasting method generally refers to 16 hours of fasting and 8 hours of eating in a day. The 5:2 fasting method generally refers to choosing two days of fasting in a week and eating normally for the other five days.

Although there are many options for restrictive eating methods, the most important thing is to choose the method that suits you without affecting your normal life.

With the increase of age, the human body will gradually age. After the age of 70, it may usher in a cliff-like ageing. Pay attention to maintenance. If after the age of 60, you still have a good appetite, flexible legs, good lung capacity, and good sleep quality, then congratulations, you may live a long life.
