lefthander

A lefthander is a person who predominantly uses their left hand for tasks requiring fine motor skills, such as writing or throwing. This preference is often referred to as sinistrality. While most people are right-handed (dextrality), left-handedness occurs in approximately 10-12% of the global population. The exact causes of left-handedness are not fully understood but are believed to involve a complex interplay of genetic and environmental factors, with some studies suggesting a role for brain lateralization, where the left hemisphere of the brain controls the right side of the body and vice versa.

Historically, left-handedness was sometimes discouraged or even punished, leading many individuals to train themselves to use their right hand. This practice has largely diminished in modern societies, and left-handedness is now generally accepted as a natural variation. Left-handed individuals may encounter certain challenges in a world designed primarily for right-handed users, such as using tools, writing in spiral-bound notebooks, or operating standard scissors. However, many left-handers adapt readily to these situations, and specialized tools and equipment are available for those who seek them. There is no scientific evidence to suggest that left-handedness is associated with any cognitive deficits or other negative traits; in fact, some research has explored potential links between left-handedness and creativity, though these findings are not conclusive.
