That effect is so strong that when my neck vertebrea had a better position for a week
in 1995 (I could be wrong by one or two years), that it was the happiest week of my life.
I have described that also in
my "own story" (in Dutch).
That was for a major part due to stabilization exercises for my neck to counter the
torsion of my cervical vertebrea, which helped when an osteopath corrected my neck.
