Haha it came from being left handed and my catholic step mom hitting me when I’d use my left hand I was young enough to then train to use the right hand but then my real mom came to pick me up from that house hold and I went back to left. I draw with my left and write fast with my right and then sign my name with my left and eat and all that with my left. Boxing I take a left handed stance till I get tired on that side and switch to right lol. It’s weird but I have a lot of input devices so it’s all good

That’s how I work with a Kensington orbit on my left and the keyboard on my right and then a Logitech ergo mouse on my right as well to switch. I’m ambidextrous.
