Man, that is because "damaged" nerwos sistem from pois, all function in
body work tru nerwos system.
You say that you cower this by exercise and keeping your spine helty.
Yeah, that use to work for me in the past, but thats only fighting
against a couse of illnes.
And when my nerwos sitem is damaged hard, i cant excersise,
couse i hawe respiratory colapse.. etc( a cant exercise on force),
nerwes do not fire propery, and thisafect ewry proces in body, from
digestion parestesis to all odher symptomes.
So when this hapen, i must heal my nerwos system wery slowly,
it tok me 6 month or one or two year to heal, and to be able
to fisicly function again.
Because of this you hawe bad posture, muscule cant work properly.
That is because of pois. It cant be healed by exersise-i did hawe all my
life to test this.
Poisers who damaged hard from ilnes(do not force exercise hard!),
do moderate, if you can make 10 steps, do 10 steps , no more,
for begining.
