My mom is, it didn’t pass down to me or my brother. I suspect she was born left handed (that did pass down to me), and it was "corrected"out of her, now she’s equally klutzy (read not at all a klutz) with either hand.
One of my recent work places actually had 1:1 left to right handed people, in a group of 12, there was even one guy who insisted on using the mouse with his left hand (we shared a couple different terminals and you could tell when he was the most recent one to use it). That man was a monster.
This should not be 8 years old… How is uptown funk 8 years old? Oh time when did you start going so quickly?
