Is lifespan determined by genetics? Is a person s lifespan affected by genetic factors

Life expectancy is partly related to genetic factors, but the impact of a life partner on longevity is more important than family genetic factors. The heritability of human lifespan is not between 15% and 30%, but it is likely to be less than 10%, and it is the life partner who will really affect the lifespan.

A life partner is someone who lives with you, and many people will choose someone who shares their own values, which are either to live longer together or shorter together. People who love fitness will choose to be with people who like to exercise, and people with bad habits will also be with people with unhealthy lifestyle habits.

Therefore, as long as you stick to healthy lifestyle habits such as good lifestyle habits and exercise habits, you can overcome genetic defects. That is to say,Healthy lifestyle habits are the key factor in determining the length of life

External factors play a role in the influence of an individual's lifespan 50 percent and another 50 depend on internal factors, of which 25 are genetic. ‍‍

Is lifespan genetic? Yes, for sure! For example, if some diseases are inherited, the life expectancy is relatively low, and if there are no genetic diseases, the life expectancy is relatively high. "Inherited traits determine a person's lifespan". This is a famous quote from the famous geneticist Morgan.

Life expectancy is closely related to heredity, the international standard of 80 years old as the longevity of the elderly, as early as the beginning of the last century, scientists have found that more than 80 years old in the descendants of a certain family, more than half of their parents have reached 80 years old, thus confirming that the life expectancy of people is related to heredity.

The American Pole examined a centenarian and found that the average life expectancy of his six direct ancestors was close to 100 years.

Therefore, some people have proposed that the life expectancy of a person can be increased by the average life expectancy of 6 parents, grandparents and maternal grandparents, and a large number of surveys and studies have confirmed that this law has a certain reference value.

Professor Li Tiejun of Nanjing University of Traditional Chinese Medicine and others spent one year on 100 long-lived elderly people in Nanjing (including the highest age of 107 years old, the lowest age of 93 years old, and 42 people over 100 years old) to conduct a survey and research on the average longevity of the elderly, the average life expectancy of the long-lived elderly is the age of the year, the average life expectancy of the elderly is only about 35 years old before the founding of New China, and the life expectancy of the parents of these birthday stars is almost twice the average life expectancy at that time.

Therefore, it can be said that genetics are an important factor in determining lifespan. The general elderly are about 85 years old, and even if they do not suffer from fatal diseases, they will face the threat of old death, while centenarians are much slower than ordinary people. Jiang Ning Ni Peiying, who lived to be 107 years old, could still go up the mountain to chop firewood at the age of 90, and could do some light work at the age of 100.

According to a 1999 statistical analysis of 116 centenarians in Shanghai, it was found that more than 40% of their families had longevity genetic factors.

Summary: Genes are embedded in chromosomes, and chromosome studies on long-lived elderly people have shown that the chromosomal aberration rate of long-lived elderly people is lower than that of the general elderly, and the proportion of sex chromosome loss is also lower.

Lifespan largely depends on genetics, and longevity genes in the body can affect lifespan, but lifespan is also related to the external environment, so lifespan is the result of the combined action of genes and environment.

It's not just genetic, there are many influencing factors. Genetics can affect one's lifespan, but a good routine can also prolong one's lifespan.

Inherited genes may affect the length of lifespan, and lifespan is not completely inherited and affected by acquired habits.

Heredity and longevity have nothing to do with each other. Lifespan cannot be inherited because heredity does not lead to a reduction in lifespan.

Many people believe that good health is related to longevity and genetic factors, and genetic factors can also affect people's life expectancy. For those who live a long life.

Among their parents or immediate family members, some are definitely from longevity.

But when it comes to longevity, the genetic factor may not be as strong as you think. According to relevant data studies, the impact of genetic factors on premature death is not as great as expected, accounting for only about 30%.

In terms of longevity, there are many factors such as personal behavior, environment, lifestyle, society, etc.

It can have a very big impact.

Even if cancer is related to genetic factors, the incidence of cancer can be greatly reduced if lifestyle and dietary habits can be changed in time.

Based on an analysis of the genealogies of more than 400 million people, it was found that the influence of life partners on longevity is more important than family genetic factors.

The statement said that the heritability of human lifespan is not between 15% and 30%, but is likely to be less than 10%, and what really affects lifespan is the life partner.

As long as you stick to healthy lifestyle habits such as good lifestyle habits and exercise habits, you can overcome genetic defects. In other words, healthy lifestyle habits are the key factors that determine the length of life.
