I'm a total lefty... my right arm (hand) could pretty much just hang there most of the time and I wouldn't know the difference. Except... when it comes to the Wii... for some reason, I Wii with my right almost as much as my left
Growing up, all of us kids were lefties, but my older brother was in school at a time when if you were left, they made you right...write.. right?

So, he became a really bad righty... and my mom swears, dyslectic after that. My younger brother writes left, but repairs mechanical things and bowls (

) righty. My new found older half-brother... is a lefty as well.
All of our parents were/are righties, our grandparents, aunts and all but one uncle... righties. I've got 16 or 17 first cousins on my da's side... all righties (as are their 10 or so kids!); 6 on mom's side... all righties.
My nephew started out messing around left, then right... and seems to be a righty so far.
So, out of approximately 60 people, 3 of us were lefties, 1 went right and dinner time was always fun with the relatives, those elbows... oi, those elbows.
I find the kindle perfect for me! I use the left to go one way, the right to go the other... and rarely if ever switch
