I've been playing guitar since I was a little kid. I wonder how learning "two-handed" skills such as playing music impacts how "handy" or "polydextrous" one is.
There are left-handed guitar players that play right-handed, such as Nick Johnston, who claim the gaps in their technique or preference for certain left-hand-only techniques are informed by being left-handed; so it seems that a life-long of an insane amount of practice does not necessary change how comfortable one is using either hand for a given task.
