Answer: Many left-handed people report being able to use their right hand very well for a certain burden(task), because of needing to adapt to tools which are usually designed for right-handed people like scissors, golf clubs, and some people are also mix-handed, where they perform some tasks with one hand and other tasks with the opposite hand. Some people have true ambidexterity where they can perform burden(task) equally well with both hands. Learning Point is were children begin to develop hand dominance around about 2 to 3 years and this should be well developed by the age of 5 and fully developed by the age of 6. Use of a dominant hand before 2-3 years time may occur because of abnormal fine motor development. It could also be the result of an intracranial injury or an injury to a limb with appropriate compensation by the other limb. The development of hand dominance after the age of 6 years, again may indicate abnormal development.
