Similar migration (IN->CA), it has changed my life. I had the worst sinus/migraine issues growing up and my breathing has dramatically improved after moving out of Midwest, even compared on the worst wildfire weeks out here.

Coming from NWI, I know the mills had a lot to do with subpar air quality, but I had similar issues when I lived on the far Northside of Chicago so it seems to be more regionally affecting.

It's a similar top reason on my list to not living there long term again
