I always joke the reason I'm never sick is that I don't wash my hands after using the toilet. I do of course wash my hands, it's mostly to get a reaction out of my GF, but I guess there is a balance between cleanliness and exposure. It's how vaccines work, right.

But being exposed to the wrongs things can also be bad. The small mountain village I grew up in is partly famous for it's children hospital ("Geilomo barnesykehus"), where kids from the 1930s and onwards would come to live, since they would be better here than in the city. Like kids with asthma and lung diseases could live a much more normal life here.
