I do agree that it could be profit motivated, however, their explainations make way too much sense.
The videos claim that the reason our head doesn't til if we walk around with one shoe on and one off, is due to the internal mechanisms forcing our head straight and what ever the muscles can do to contort the spine and or hips to acheive a straight head, is what our body seems to do.
I would like to find out if this is infact true.
However, If the atlas orthogonal treatment is false, the Dorn method is the best alternative to back correction I have seen, yet.
