Writing, throwing a ball, snooker cue, tennis bat (or whatever it's called), baseball bat and anything that requires fine motor control - left handed
I have left-handed scissors in the kitchen, and a left-handed ruler in the office.
Playing guitar, cricket bat - right handed
Catching a ball, using a knife and fork - either way.
Phones, calculators, PCs and pianos are only made in right-handed forms. I use my PC mouse in my left hand but with a standard right-handed button configuration. In reality, most left-handers can use both hands to do things; we have to, because the rest of you lot simply refuse to cater for us
How many guitar manufacturers fail to make a left-handed model? Isn't PRS one of them?
