I'm mostly ambidextrous. I'm left-handed, but do dishes right-handed most of the time, and when I had to work in a kitchen for 8 weekends at a renaissance festival, I really, really had to alternate back and forth to give relief to either scrubbing hand, and plus, the pans were so big that it made sense to wash to one side with one hand and to the other with the other hand. I play drums open-handed (left hand plays hi-hat and other cymbals on the left side and the right hand plays other cymbals on the right side for time-keeping) on a right-hand drum set. Also, I lead on the drum set with either foot regardless of what my hands are doing.
I even tried to learn to write right-handed while I was learning to open up my drum playing style. I could do block print somewhat, though slow. A few years before, I changed my left-handed writing from southpaw with ink on the hands to underhanded with the paper facing 70 degrees clockwise from upright. It took me about a year and a half to do this.
I'm surprised that some people have trouble starting a mower right-handed (when the pull-rope is threaded on the handle on the right side). I guess I don't understand because I am not side-dominant. However, it would be interesting for me to shoot my handgun again left-handed, which I have not done in 35 years since I start going blind on that side from cataracts. Now that I've had that surgery done on the left eye, and now, glasses for the right side don't correct anymore (I have monocular polyopia, so even when I see clearly, I don't see a single image, but multiples superimposed one over the other), and the right eye becomes nearsighted after surgery, I won't be shooting right-handed anyway.
