I'm right handed, but I seem to do all sporting-related things left handed, except throwing. Boxing, gymnastics, skateboarding/surfing, etc. I do as a left-handed person would. I also open jars with my left hand. Weird.
im ambi dextrous, i can use both, its really strange sometimes, cos i dont consciously think about it then someone wil lsay " hey u did yhat with your right hand two minutes ago lol"
