Handedness refers to the preference most people show for using one hand over the other for tasks like writing, eating, or throwing. The majority of people are right-handed, meaning they find it easier to use their right hand. In contrast, about 10% of the population is left-handed, using their left hand more often. Some individuals are ambidextrous, meaning they can use both hands with equal skill. Handedness is believed to be influenced by genetics and brain structure. Studies show that left-handed individuals may have different brain organization compared to right-handed people, which can affect how they process information and perform tasks.
