I was in a pub quiz team which had three left handers and three right. One of our various team names was "Sinisters and Dexters".
I write left handed, use a spoon left handed; ambidextrous with knives (though prefer chopping, carving with left), screwdrivers, scissors, pc keyboards, sanding, painting (walls), tennis, badminton; right handed playing cricket or golf (not that I do but when I tried them I did) and most weirdly using a mouse. I spent nearly 30 years doing fairly intricate arty stuff in Photoshop, Illustrator and so on with my right hand, whereas with a pencil, pen or brush I'd use my left hand - which cannot accurately use a mouse. Conversely, try using a joystick with my right hand and things are all over the shop... I have one I use with FS, I'll make a conscious effort to fly a few circuits and do some aeros right handed later on, see if I can train it.
