I am a right handed person but wish could use the left hand also for writing etc. I have heard that you should use both your hands, as the left side of the brain controls your right hand and the right side of your brain controls your left hand. So better to use both sides of the brain, is'nt it. I think children, if they are more comfortable in using their left hand, should not be forced to use their right hand only. And yes, I have observed people using both hands are special, perhaps more intelligent.
