The body is an amazing thing. We all have different physical characteristics, we also differ in different talents and mental abilities. Unusual features set us apart from those around us. We observe one of them every day - this is the difference between people, some of us are right-handed and others are left-handed.
Scientists argue that if a person can easily control the left hand, then this should not be hindered and try to fix it. The world's left-handers are about 4 percent. If you look into history, it turns out that many geniuses were left-handed, for example Leonardo da Vinci and Michelangelo.
There is no generally accepted explanation why most people are right-handed and others are left-handed. One theory is that our body is asymmetric, that is, the right half does not exactly repeat the left half. The right side of the face is slightly different from the left, one leg is slightly longer than the other, the feet are slightly different in size. This asymmetry is observed throughout the body. The right and left hemispheres of the brain also function differently, and it is assumed that the left hemisphere is dominant over the right. The nervous system connects each hemisphere to the opposite side of the body.
In the case when the left side of the brain predominates, then the right side of the brain is more perfect. With the help of the left hemisphere of the brain, we read, speak, write and work. This explains the fact that most of us are right-handed. In left-handers, the right side of the brain predominates over the left, as a result of which left-handers have better control over the left side of the body.
We live in a right-handed society, and most of the items we use are made for just such people.
August 13 is recognized as World Left-Handed Day. This day was recognized for the fact that people began to pay attention to the various problems of left-handers.
The most surprising thing is that the percentage of gifted people is very high left-handed people. Mozart, Beethoven, Raphael, Charlie Chaplin, Napoleon, Albert Einstein, Robert de Niro, Julia Roberts, Bruce Willis, Tom Cruise, Sylvester Stallone, Jeanne d'Arc, Bill Clinton, Bill Gates - they are left-handed!
It is curious that if you observe newborn babies, you will notice that they take more often with their left hand.
There are many sports today where left-handedness is an advantage. Lefties are very much appreciated in sports, as they have non-standard techniques. They kind of mirror the game. For example, in boxing. Did you know that left-handed boxers generally win 35% - 40% of gold medals? They are agile and unpredictable in the ring.
