I can't believe some pussies are freaked out by a few fucking worms...
It's not like you're living in a 3rd world country and you're going to die of starvation because of them.
There is a slightly controversial theory that states the reason why people have allergies and things like crohn's disease--a digestive disorder--is because during our evolutionary history, our immune systems developed with parasites. Now we're too hygenic, our immune systems are in overdrive and we get shit like allergies, crohn's, etc...
Eat your damn sushi and take the worms like a man!
