Didn't one reason have to do with inks in the past did not dry as fast as
they do today so most people learned to write right handed
not to smudge the ink.
Another reason , I am a lefty but years and years ago I had to learn right handed in Catholic school. I think , but not sure, it may have had to do
with some of the definitions of "sinister":
1. situated to the left side of something
2.of ill omen by reason of being on left
3. accompanied by or leading to disaster or unfavorable developments
I think I'll stick with the right hand just to be safe
