I doubt it. My wife and I were completely allergy free until 4 years ago. She developed a bunch of allergies then. I'm picking up some over the last 12 months.

I don't think too clean applies in my case. I'm a firm believer in the 5 second rule :) A friend of mine developed serious allergies over the last few years as well. Sure, it could just be age. But there's a two decade age difference between my friend and me. I've so far blamed it on LA's air quality, but it's interesting to see it seems to be part of a wider trend. (I have no idea what causes it, but I suppose that article means I should widen the search for potential causes.)
