That's a peculiar thought. I would expect that you would run into other issues -- Namely, that you would wind up having to design your own unique keyboard to accommodate your extra digits, as the spacing and alignment/arrangement of existing keyboards would not fit your physiology?
It would be a very interesting thing to evaluate and see if there are any other people with similar physiologies, and see how it has helped or hindered them, and what obstacles they had and benefits they reaped.
Though, I do suppose that also depends on your own interest in things like that. For those of us who have not had the same experiences, it would be interesting, for you, it may very well be boring by this point.
Funny how our perceptions can vary so much based on our own experiences with any given subject.
