I am left handed, that is I write with my left hand.
However when using a long ( rifle ) I shoot right handed.
When I use a short ( pistol ) I shoot left handed.
It gets even worse.
I play cricket been English. I bowl left arm spin but when I bat I bat right handed.
I play the beautiful game football and I am predominantly play with my right foot.
When I train at karate my main punching arm is my left and in competition I fight left handed, but my kicking power comes from the right leg. So not only do I have a very unorthodox stance and it confuses the hell out of an opponent.
I play golf as well, and you guessed it I play with right handed clubs, but I always eye up my next shot from a left handed perspective.
I did do some fencing in my twenties and a always used a foil with my left hand.
So God only knows how my brain is wired !
