Those writing in the left hand are smarter

There's a lot of rumors about left-handed people, so those whose dominant hand is left.

Some studies suggest that left - ageds die younger, some research claims to be more aggressive, and others suggest that left - handed people consume more alcohol.

Although such claims are rejected and do not have strong scientific support, there is actually a myth that weighs more, which says that left - handed people are smarter than right - and has been suggested that left - handed ones are more likely to become genius.

) The IFL Science has revised several studies regarding dominant hands and mathematical skills to test this theory.

They explain that the function of the hands is a manifestation of the function of the brain, and therefore it is linked to the cognitive abilities.

According to them, lefty, right side of the brain is larger, and this helps them with spatial skills and mental reflections of objects.

Besides, they also have better connections of nerve cells that connect two brain hemispheres to each other.

This means that they have greater connections on both sides of the brain, so they tend to process information faster than do the right.

Among other things, studies and experiments with thousands of people also show that lefthands are better in mathematical skills than rightist ones.
