>>102463why would it be bad? if anything I've found it very beneficial to be able to do some stuff with one hand and some with the other. makes it easier to avoid repetitive stress injuries of the hands.
you can ask your family doctor/GP about it, but probably 2 things will happen:
>he'll wonder why you think this is even an issue>the test will consist of him asking "what kind of things can you do better with your right hand? with your left hand? what can you do equally well with both?" and if you list off more than a couple things for either side he'll say "congrats you're cross dominant and/or ambidextrous" and send you on your way
