Playing with both tongues as I sit and read the internet. Again not too long ago I could not imagine that the tongue musculature would have any impact on my posture and/or use of myself. It is soft tissue therefore it's impact on the skeletal system should not go past it's immediate insertions into the skeletal system.
However that is not what I am feeling. I am unable to even 'jackass' a good reason how much the tongues's impact feels to have.
