I am born left handed and made to change at school and there are some things I have a problem with.
Chopsticks is one of them - although I write now with my right hand, I use my left for chopsticks, and think my brain is totally confused.
I DO sometimes use the chopsticks when eating out at Asian - mainly when we are given them, but sometimes, and depending what food it is, I ask for a fork and spoon half way through the meal.
Chopsticks are good for me, however, as I am a very fast eater and eating with chopsticks slows me down considerably.
speaking of using the other hand, I read many moons ago that one should use both hands as it excercises both sides of the brain, meaning the left hand uses the right side of the brain and vice versa. So I taught myself to use the left hand for many tasks like brushing teeth, picking up, stirring etc etc.
