That happened to my father in school since they still used ink nib-pens and if you wrote with your left hand it'd smudge all over the place (also a reason why lefties write with their hand curled over the top of the line being written).

Anyway, he passed his left-edness onto me, so count me in! I write, solder, play racquet sports, pool cue, throw a ball, all left handed, but guitar, cricket, golf, I do righthanded.

With snow/surf/wake boards I stand 'natural' FWIW.

I also meant to say [missed the post-edit time window!] that after my father was forced to learn to write with his right hand, decades later he was still able to simultaneoulsy write with both hands!

He also happened to be able to paint landscapes of above average quality - now that I would've like to have inherited also!
