Picture yourself holding a pen. Put that pen up to an imaginary piece of paper on an imaginary desk and pretend to start writing. Which hand did you use? The hand that you picked to write is your dominant hand, and the choice you make is called handedness.
Most likely, you put up your right hand. A small percentage of you would have put up your left. If you are in an Asian country, let’s say Việt Nam, it would be an even smaller percentage.
So why is this? Loa’s Chí-Linh Đinh was wondering the same thing, so she tries get to the bottom of handedness in Việt Nam.
