Why are some of us right-handed and others left-handed is an eternal question that was already dealt with by Plato. Scientists today are still wandering in the dark, although many theories have appeared, but all of them are as holey as Swiss cheese. The one about two economists and three opinions applies here. Some scientists say that the side is conditioned by genes, others that it is acquired in the womb or before birth or. it is a matter of changes in the environment.
left-handed
The words leftist and rightist have had a rather negative connotation ever since they came into the hands of politicians. But let's wave our hands - right or left? - at this definition and rather focus on the real problem of leftism and rightism, which is not political, but biological in nature. In a world tailored for right-handed people, it's not easy for left-handed people.
