Why are people left-handed... are they really smarter...?
Barely ten percent of people around the world are left-handed, so they are always considered special (smarter)… but is this really true?
Actually, the whole story is related to their genes. They have a special kind of rare gene in their body, which controls the size of the cells in their body. This gene is found 2.7 times more in the body of left-handed people. The name of this gene is TUBB4B. It controls the symmetry of the brain i.e. balance.
Medical experts do not associate it with any disease or medical specialty. According to them, this is a normal process. Just like some people work with their right hand, others work with their left hand.
The second major reason is the learning and social environment. In this, some children use one hand more during the learning process. Many children start working with their right hand. Gradually, this hand becomes more active.
In childhood, many people do not develop energy management patterns in their brains. Due to this, their brain does not indirectly force them to write with their right hand.
