The complexity of learning to use this bone and tongue has got to be immense yet somehow I learned it along with 99.9% of the population. I have spent a great deal of time playing with the minutiae of these muscular movements and I have probably just scratched the surface of what I do by habit. What I do feel is the left muscular control is no where near the right side control in the mechanics of speech. Swallowing also feels to be somewhat more 'understood' on the right side.
What it feels to me the preference in the tiny sets my preference in the large.
