Uhm, that's all possible but 'sick' is rather general. IIRC there was an article here recently where children growing up on farms were compared to children growing up in cities and the consensus was that because the farmers were more exposed to typical 'farm dust' (think pollen, animal excrement, ...) they were less likely to develop all kinds of allergies (indeed: pollen, animal excrement, ...) than those from the city, and less allergies in turn means less prone to asthma and other respiratory problems etc. In other words, that article is like exactly the opposite of this title, in a way.
