"What if I told you," Joel Weinstock said, "there were countries where the doctors had never seen hay fever?"  
It is another piece of evidence, another "aha" moment in the global medical mystery that Weinstock — the chief of gastroenterology and hepatology at Tufts-New England Medical Center — has narrowed down to one chief suspect: the worms.  
Weinstock, 59, specializes in studying why immunological diseases - everything from hay fever and asthma to diabetes and multiple sclerosis - are on the rise in developed countries but remain relatively uncommon in undeveloped countries. He believes these diseases, many of which were almost unheard of 100 years ago, are because of changes in our environment, a lack of exposure to something. And he thinks that something may be the worms.
bear: great POST!! read it
Darwish: huh
vinfille: "Public hygiene and cleanliness are very good for us, but removing ourselves entirely from our natural environment is bad for us. We need to figure out the aspects of dirt and exposure that are good for us and hopefully we can find a balance."  
I'll buy that.
bear: we've seen this before in many realms, we try to mess with reality without truely knowing the consequences and it usually ends up being really bad and resulting in unexpected side effects. Stop washing so much, play in the dirt, stop the MUTATIONS!
