It doesn't matter which hand holds the fork.
Half the time I eat with my left, and half with right. I don't even think about it.
I can also do left handed lay-ins all day long until they force me right, which is fine with me.
When I plumb, I normally use both hands at the same time, but doing different things.
When play guitar, I use both hands,
I also bat both left and right.
What's your point anyway?
