Right-handedness refers to the preference for using the right hand for tasks such as writing, eating, and throwing. About 90% of the population is right-handed, making it the most common hand dominance. This preference is often linked to brain function, as the left hemisphere typically controls the right side of the body. Being right-handed can influence various aspects of life, including the design of tools and everyday objects. For example, many items like scissors and computer mice are designed with right-handed users in mind. This can sometimes make tasks more challenging for left-handed individuals, who may need to adapt to right-handed tools.
