I write and operate a mouse with my left hand.
I play cricket ( and golf, if I played, but do not) right-handed.
I can use a hammer equally well with either hand - useful when you get tired.
Archery - I would hold the bow in my right hand and draw with my left.
I use a fly rod in my left hand, but can cast with a double-handed salmon rod either way round.
Also, I wear my watch on my right wrist - it would be too prone to damage on my left.
My wife is left-handed and so is our daughter.
