Yes, as a matter of fact I did know that.
My dad is ambidexterous, he is left handed but when he was younger he broke his left wrist which forced him to learn to write with his right hand and still to this day I sometimes see him writing with either hand.
You know what would be amazing, and I've seen this before, someone writing with both hands at the same time! Actually I've seen someone write with both hands and both FEET at the same time!.....Now thats amazing!
