It's a strange thing. I have twin uncles that live together and work in the same area doing similar jobs. One got put on his ass for 2 weeks and lost some weight while the other just had mild symptoms during the same time frame. Identical twins who cohabitate and have basically the same lifestyle since they eat together and their jobs have them doing the same amount of physical labor. They're qtards as well so they've been red pilled to all of the natural remedies available for dealing with more typical illnesses. Yet they had two completely different experiences with the stuff. They think it has something to do with blood types but I can't recall if that was a theory of theirs from before they got hit with it or not.
