I'm ambitextrous. I do write with my right hand, but can print with either as long as I take my time. My writing is awful with either hand if I write fast, anyhow.
Depending on what I'm doing, I might use my left hand more than my right or simply use whichever hand is closest to the task. Way back when I was physically able to play tennis, I would switch hands rather than use a backhand and have the same strength and control with either. The same went for batting, etc..
The one thing that my wife has observed is that I eat with my left hand, but switch to my right hand for dessert. I have absolutley no idea why, but it's pretty consistent.
Some years ago I had my right arm in a sling for a few weeks and found there were only a few things that were awkward with just my left hand, but it's surprising how many things we do with both hands, like washing your face.
