Why left handers live an average of ten years less than right handers

This is because the left brain is responsible for reasoning (concrete) and the right brain is responsible for imagination (abstraction). Because of the crossed nerves, the left brain controls the right hand and the right brain controls the left hand. Theoretically, people with inferential thinking are more flexible with their right hand, while people with divergent thinking are more flexible with their left hand, and which hand does things is the same for the individual.

However, people are highly adaptable advanced animals, and the existing social life facilities, as well as family education, limit the development of "left-handedness". I know you still want to ask if you are not left-handed in the first place? This is because the first human minds were inferential and the vast majority were "right-handed".

What is Reasoning Thinking? For example, you suddenly ask someone 1+1 on some formal occasion (not very 6+1). , ask for half a second to answer, the first reaction of the average person is to wait 2, this is reasoning thinking, simple and practical, hehe.

The social facilities and rules of life created by right-handers, including the way of writing, have left little for left-handers, and it is difficult for left-handers to adapt if they do not want to. But some of my friends who are good at playing with computers seem to use the mouse with their left hand. Specific to playing table tennis (because you are asking in the column of table tennis), according to all mankind-"China-" table tennis players, to push in this direction, there are still few left-handers who play table tennis, and the whole number is small.

Left-handers in table tennis have more development than left-handers, because left-handers usually practice right-handers, and right-handers practice very few left-handers, so the team will also consciously call some left-handed sparring partners and train a small number of "left-handed" players to achieve excellent results. Such as Wang Nan, Guo Yue, Chen Qi, etc., are all left-handed table tennis players. In fact, if the function of the human brain is initially reversed between the left and right brains, then your question today will become, "Why are there more left-handers than right-handers?"

Hehe, ugly opinion, for a laugh.

Because left-handed people are more handsome than right-handed people, they are jealous of God.

Because left-handed people often use their left brain, they use their brains more than right-handers, and left-handers also use their right hands to write, so they have more brain cells than ordinary people.

On this subject, there have been some studies that have suggested that left-handed people have a shorter lifespan than right-handed people. A survey of 2,379 people serving in the Navy by an American researcher at the California Naval Talent and Development Center revealed that left-handers may be more likely to have accidents, in part because they have a slightly greater tendency to have inattention. There are also some studies that believe that most of the existing devices are designed for right-handed people, and it is they that cause left-handed people to be prone to accidents.

These artificial reasons make the average lifespan of left-handers a bit shorter.

Other studies have shown that left-handed people are not at risk to their health. Scientists from the National Institutes of Health and Harvard University conducted a six-year study of the mortality rate of the elderly in East Boston, Massachusetts, in 3,775 people over the age of 65. As a result, there was no significant difference between the mortality rate of right-handers and that of left-handers.

In terms of the natural health of the human body, there is no difference between left-handed and non-left-handed, and the lifespan is the same.

There have been some studies that believe that left-handed people live shorter than right-handed people, but there is no scientific basis for this. Because in terms of the natural condition of the human body, there is no difference between left-handed and non-left-handed, and there will be no difference in the length of life of left-handed and right-handed.

There is no scientific basis, this is actually genetically determined, and it has nothing to do with lifespan or anything.

There is no scientific basis, this is just a false statement by people, just such a one-sided statement, without any evidence to prove it.

I am a pig left-handed, Libra female, blood type B.

It's nonsense to say that left-handers are more likely to die than right-handersIt's certainly not true.

So-called left-handers are more likely to die than right-handers, and some so-called case studies have even been proposed. I just read the case studies, and in one case, for example, I found 2,000 people, some left-handed, some right-handed, and he ended up finding that left-handers died nine years earlier than right-handers.

It seems that this case has proven that left-handers are indeed more likely to die than right-handers, but this is only a probability among those 2,000 people. Moreover, in addition to the difference between left-handed and right-handed, they also have other objective physical condition factors, etc., which are not included in the calculation, so such a simple judgment is not based on scientific evidence.

There is also an army that conducts a probabilistic analysis of left-handed and right-handed values and finds that left-handers have a mortality rate of 38 per cent and right-handers have a mortality rate of 32 per cent. In fact, in terms of the probability of death, the difference between the two is not large, and he did not set other conditions to be the same, so this case cannot be used as a basis for conclusion.

I also have some left-handed people around me, like my cousin, who is left-handed in her family. His grandfather died in his 80s, and his father, who is also my uncle, is now in his 50s and is very healthy. My cousin is a person who can shoot a bow left and right, and has been alive and kicking since she was a child.

If you only look at the analysis of the people around me, left-handed people not only do not have a very short lifespan, but even they have a very long lifespan, and they are particularly healthy. Of course, their family is just an example, and it cannot be used as a typical representative of left-handedness, but it also shows the health of left-handers from another perspective.

Many people believe that left-handers are more likely to die than right-handers because of superstitious thoughts。Because in ancient times, it was believed that if he was different from ordinary people, then this person was unlucky, then he received very little care, and in a harsh environment, if there was no one to take care of him, of course, it was easy to lose his life.

There are many things that accumulate for a variety of reasons that cause this result. There are a lot of left-handed people around, and their lives are not much different from ordinary people. They are all growing up healthy, some people are still very good at school, have a stable job, have a happy life, and these people are also healthy and long-lived.

The claim that left-handers are more likely to die than right-handers is completely unscientific。It's just a subjective assumption. For example, some people are more likely to have accidents than right-handers, because many things are originally designed for right-handers.

But such so-called accidents can be overcome.

A person's life expectancy is composed of many, many factors, such as your own health foundation, such as some of your lifestyle habits. These factors certainly have a much greater impact on longevity than left-handed or right-handed people. Your claim that left-handers are more likely to die than right-handers is inherently false.

Assuming that there are more right-handed people than left-handers in the world, then left-handers are more likely to have physical collisions when working with right-handed people, which means that left-handers are more likely to have conflicts in the world, just like the butterfly effect; But this is only an assumption from the point of view of life.

There is no scientific basis for this. Don't take the rumors for it. These are just hand habits that have nothing to do with longevity.

Twelve years ago, American psychologists Kong Rong and He Peng suspected that left-handed people would live an average of 9 years shorter than right-handed people (66 years old). Later, the research community refuted their fallacy and forcibly supported their hypothesis (a left-handed person driving a car designed for a right-handed person, operating with a backhand, and reacting in an emergency). Kong Rong and He Peng asked the families of the 1,000 car accident victims in a town in Southern California whether the deceased were left-handed or right-handed before their deaths, but only three people turned left, and there was no way to prove whether the three people were indeed killed in the car accident because of left-handedness.

Diana, a professor of psychology at the University of California, San Bernardino. Stanley, a researcher at the University of British Columbia, Harpens. After reviewing the death certificates of 987 people in two Southern California counties and asking the relatives of these people by email whether the respondents were predominantly left-handed or right-handed, Colin found that the average age at which right-handers died was 75 years and that the average age at which left-handers died was 66 years, as the landlord said, right-handers lived 9 years longer than left-handers.

At the same time, they found that left-handers were four times more likely to die from injuries while driving than right-handed people, and six times more likely to die from various other accidents than right-handed people. "Almost all of the tools are designed for people who use their right hands and feet, and left-handers are exposed to more car accidents and other accidents," Halpen said.

Left-handers are smarter Think things are different from others, left-handed people often have a formed image in their minds before writing or drawing, and many left-handers will also find a way to reassemble the fragmentary data that they can't memorize into a page of pictures, and then memorize it.

This claim is not scientifically based and inaccurate.

I don't think it's inevitable that it's just accidental.

Not necessarily, it's just an accident.

No, it depends on the individual.

No, there are rumors.

This may or may not be accidental.

I don't know, it's not scientifically proven anyway.

I don't know, there's no scientific evidence to prove it.

Right-handers should be normal, and left-handers shouldn't be smarter.

Because it's a natural phenomenon.
