According to WHO, 60% of a person's health and longevity depend on lifestyle, 15% on heredity (genetics), and the remainder on medical, social and environmental factors, for a total of 25%.
But there is a phenomenon that is very troubling: that is, people are born with diseases, such as someone who has congenital heart disease or cerebral palsy in the mother's womb, this situation can be said to be predestined, or genetically determined;
But some people smoke and drink and live more than 100 times!
For example, the world's longest-lived man, Maba Gaoso of Indonesia, was born in 1870, one year older than Emperor Guangxu of the Qing Dynasty, at the age of 146.
Mabagaoso is a smoker, and basically smokes every day;
Zhan Changcheng, the oldest person in Zhejiang, just celebrated his 110th birthday in March this year, and he has also smoked all his life and often drinks alcohol.
If we compare those who smoke and drink and still live a long life, with those who are born with serious diseases, including those who get sick at a very young age, then the former must be very good genetically, and the latter is very poor, if the former's genes can get 100 points, the latter's score is probably close to zero.
If genes can make a person live more than 100 years and can also cause him to be born with serious diseases, why does the WHO believe that genes account for only 15% of a person's lifespan, instead of 85% or more?
In fact, these friends have ignored an important premise, that is, these long-lived elderly people and people born with diseases only account for a small percentage of the total population, and are not representative at all.
If 3.5 billion of the world's 7 billion people smoke and drink and still live more than 100 years, while the other 3.5 billion are born with diseases, or they live a healthy lifestyle, but they still cannot live long, then it is enough to show that genes are the most important factor in determining people's lifespan, otherwise, it cannot be said that genes are the most important factor in determining lifespan.
In fact, this problem is like the rich and poor of people: the rich and the poor are always in the minority, and the ordinary people who are neither rich nor rich nor impoverished are the majority, and there is not much difference between everyone.
If you don't believe it, you can observe that except for the long-lived elderly and a few people who died young, most of them have similar physical conditions, and the average life expectancy is about seventy or eighty years old.
Therefore, those who eat and drink, smoke and drink, stay up late and do not exercise, do not make excuses for their unhealthy lifestyle habits.
Besides, those long-lived old people, although they have some bad habits, but their lifestyles are basically reasonable.
For example, 110-year-old Zhan Changcheng is an old man, who goes to bed early and gets up early every day, doesn't like to meddle in things, takes a lunch break after lunch, likes to bask in the sun, does some work within his ability, never picky eaters, etc., these are some good living habits.
Just imagine, if the old man Zhan Changcheng smokes and drinks heavily, overeats, stays up late, and does not exercise, then not to mention that he has lived 110, it is a question whether he can live to be 70 years old.
So in the end, the WHO is very correct in saying that 60% of a person's life expectancy depends on lifestyle and 15% on genetics, and this conclusion is suitable for the vast majority of people.
Therefore, we must unswervingly oppose geneticism. It is completely wrong and very dangerous to attribute all human health and longevity to genes.
This is equivalent to the relationship between intelligence and success: under the same conditions, people with high intelligence are indeed easy to be admitted to prestigious universities, but people with high intelligence, if they play games and sleep every day, can only become scumbags, and they can't even go to high school;
On the contrary, students with average intelligence can still be admitted to first-class universities with correct study methods and hard work.
