Change aptitude. I practice using non-dominant hand to see the various activities such as regular hand writing. I changed the left hand To stimulate the brain to work more.
I personally prefer the practice using the hand is not in accordance with the various activities. View normal, right hand writing was changed to left hand tends to stimulate other brain function.
Change the private-handed. I practice using the hand that is not handy to see what other activities such as writing with his right hand, it changes in a normal left hand, to stimulate the brain, on the other work.
