"Left-handed" refers to individuals who primarily use their left hand for tasks such as writing, eating, and throwing. This trait is known as left-handedness and occurs in about 10% of the population. Left-handed people may have a different brain organization compared to right-handed individuals, which can influence their cognitive and motor skills. Many tools and products are designed with right-handed users in mind, making it challenging for left-handed individuals. Some common items that can be difficult for them include scissors, can openers, and computer mice. Despite these challenges, left-handed people often develop unique strategies to adapt to a right-handed world.
