I don't think it is born. But I felt curious when I was in teens after reading stories in Jing Yong's novel about Zhou Botong's trick. I started to practice to hold chop sticks in left hand and after a month practice. I can do it without problem.
But some friends noticed that I always unconsciously switch hands when picking up trash on the floor or opening doors. They mistook me as left handed. And you read from Wikipedia that a theory of ambidexterity is that most ambidexterity are in fact left handed by birth. So maybe I just forget my unhappy experience during the right handed when I was kid.
Emm, interesting. I'm always curious of how to work more with left hand (I'm right handed). I started with using mouse/touchpad with my left hand, but when it comes to writing with a pen or using chopsticks, my left hand always makes me feel dumb ... I guess more practice is needed. Gonna try that in the next month. Thanks! :)
