Im familiar with that study. Just not with your conclusions. I dont know
from where youve drawn them. Good sanitation is associated with poor
progression, so is polution, so is place of growth until the age of 15, and
on and on. None of which were controlled for in that study. Sorry for
being snide sounding, but it doesnt reach the conclusions that you fear. I
wouldnt worry. Sanitation has gotten worse, thats good, pollution has
gotten better, thats good, and now we know sun is good, and youre in the
right place for it. I really wouldnt worry. Thats an old study.

Think of things this way... Lets say you have a bag of M&M's. All colors
represented equally. You reach in, grab a handfull, and count your colors.
You get 12 blues, 6 reds, 9 greens, 14 yellows. Moral, sometimes stats are
so jumbled their meaningless. If you have MS, youre in a better spot than
those north of the 45th paralell. Lets look at the silver lining, your
chances of optic neuritis are far less. (probably because of more sun.)
