handedness

Handedness refers to the preference most people have for using one hand over the other to perform tasks such as writing, eating, or throwing. Typically, individuals are right-handed or left-handed, though some are ambidextrous, able to use both hands equally well. This preference is influenced by brain dominance and genetics, affecting motor skills and coordination. Handedness is a normal variation, reflecting how the brain controls movement and fine motor skills, and it generally appears early in childhood. It does not indicate ability or intelligence, merely a natural preference for one hand in specific activities.
