One sort rewires the brain in a funny way, and the other sort is a mirror image brain pattern. (That's a very simple explanation, so please don't jump on me. I can't take that just now.)
Anyway, there are a lot of theories about lefthandedness leading to all sorts of things, good and bad. A fair number of those things are practical -- raise your hand if you can use a spiral notebook comfortably? AHA! Betcha you're right handed! Some statistics about life expectancy are just plain wrong -- because so many people were forced to use their right hands, even though they were left handed.
And then there are the mixed/crossed dominants, or those who had to change hands because of injury. I can't do nearly as much with my left hand after a wrist injury, so virtually never write with my left hand anymore. (You can bet my handwriting stinks...) On the other hand, I always did certain things with my right hand -- scissors come to mind, and teethbrushing. Oh, and shooting baskets, although I do play tennis lefthanded. (Except that my wrist can't do it anywmore) About the only thing I really can't seem to do with my right hand at this point is eat -- cannot, for love or money, hold fork or spoon in my right hand.
Sorry. Tangent. Interesting subject to me, though.
