A recent study by scientists has shown that there are approximately 2-4 left-handers per hundred people, and more of them are among men.
They are born mainly in the second half of the year, and left-handed people are more common among industrial workers. It is not very convenient for a pronounced left-hander to live and work in the "right" world.
Parents and teachers do their best to retrain such children in childhood, make sure that everything is done with their right hand, without realizing that it is absolutely impossible to do this. It is strictly forbidden to retrain left-handers because this causes significant damage to the child's psyche.
Scientists and physicians explain this feature by a different organization of interhemispheric connections in the brain of a left-handed person and admit that this phenomenon has not yet been sufficiently studied.
