None ! Because left handers rule !
Some of us are cuter 🤗
I used to be right handed, then I had some issues and I am now ambidextrous. I'm as bad as my right as I am with my left. I haven't seen a huge difference.
Well, other than the whole world is designed for the righties, I guess there is no advantage. Unless, of course you want to use a pair of scissors, a fountain pen, fire a m-14 with blank rounds, operate a chainsaw or a skill saw. Even my vacuum cleaner is designed for a rightie. But no adavantagwe....
They write good.
