[quote name='Maklershed']I guess its possible but I find it hard to believe that there are people who, without training, can do things equally well with both hands and don't favor a side in the slightest bit.[/QUOTE]
Just because somebody favors their right hand doesn't mean they can't do everything with their left hand. I have a friend who is ambidextrous, and he can use both of his hands equally, but usually uses his right because the world is built for right handed people.
