3. Lefties are good in multitasking
Apart from the ability to use both sides of the brain, lefties have the ability to make their brains think quickly. With this, they are able to process large and often complex unorganized information at once and at a faster rate. This ability therefore allows them to easily multi-task unlike the rest of us righties who heavily rely on one side of our brains. This is because communication between the right and the left hemisphere in lefties happen quickly. This simply means that the more dominant the left-handedness the better the abilities.
