I agree with that. Include the isolation from farm living. I think I read that kids who grow up on farms has lots less asthma than city kids. My city kid husband had asthma as a child but has now outgrown it although he still has hay fever. I spent some time on a farm in my preschool years and no asthma.

Around here there is ragweed pollen. They have very big spores. If one gets in your nose, you are going to have red eyes and a red nose and sneeze a lot. That's to prevent weeds from growing out of your nose:)

"I think I read that kids who grow up on farms has lots less asthma than city kids."

Years ago asthma was considered and mostly a first world disease. Poor kids who didn't spend time indoors except to sleep didn't get it. It correlated with something a horse trainer told me, horses raised shut up in heated and air-conditioned barns got heaves and those in open ended barns didn't.
