The "Left Side" typically refers to the left half of a person's body or an object. In human anatomy, it includes the left arm, left leg, and organs such as the heart and left lung. The left side is often associated with specific functions in the brain, as the right hemisphere controls the left side of the body. In various contexts, "Left Side" can also refer to political ideologies, particularly those that advocate for social equality and government intervention in the economy. This includes groups or movements that align with socialism or progressivism, emphasizing collective rights and social justice.
