@Jeber My spouse is likely a lefty. He was forced to write using his right hand because we are old and were born in the dark ages. While he is not totally ambidextrous, it really does give him an advantage when he is doing certain things.
@Missclimpson @Jeber Many years ago I read there were no left handed Japanese children. I don’t know if this was true, even then. Still, it felt believable given my spouse’s experience.
