I'm right handed. I can't write or eat with my left hand but otherwise it's not that much worse doing stuff with it. Interestingly enough I apparently aim with the bow like a left handed person iirc.
My dominant hand is the right one (unsurprisingly). With my left I can do some basic things like eating, brushing teeth etc; my handwriting with it is pretty ugly and it's slow but the result is more readable than not.
…not really sure what it means to be "good" with a hand 🥴
