Right but i am not too bad with the left. Found this out after having to spend 5 days in hospital with my arm raised over my head :D Long story, tl;dr: don't try to break up a bull terrier fight with your hands :D
I used to be left-handed in writing, right-handed in Everything else. Now I'm right-handed in Writing and using utensils that require a hand, but everything else that involves the rest of your body, I'm a lefty.
I'm Ambidextrous but I lean towards my left hand for writing and eating. If the right is more convenient at the time I'll use it instead =) the handwriting is pretty much the same except I slant opposite. Haha
I probably would have been left handed but my grade school taught children to write with this basic step, "Pick up your pencil in your right hand." Now I'm kind of mixed handed. I write right handed and use a mouse with my right because that's just the way I was taught to do it, but most sports I'm left handed. However when it comes to arts and crafts I use both hands equally, and I make just as big a mess with glitter no matter which hand I use :P
Lefty, but I mouse with my right hand. And cut with my right hand. Almost everything else I do right-handed except write. (As a kid I was too embarassed to ask for the lefty scissors when our teacher was passing out scissors.)
I am a rightie; interestingly, my father-in-law was born a natural lefty but is now ambidextrous because the nuns in his catholic school beat him into it. Apparently being left handed is from the DEBUL!
Also i bowl dismally with both hands. I'm better when adding large quantities of beer.
