I’m in Southern interior Alabama. There’s no way I’m giving up my air conditioning, even if I cough and hack half to death all summer long.
I’m not saying it’s right for everyone; I know that some regions really need central air conditioning.
But I spent the first 34 years of my life with nothing but radiators for Winter, and plenty of cross ventilation with a fan in a window here and there in the Summer.
When I moved out of there into places with HVAC, I developed all kinds of sinus and allergy crap that I’ve never gotten over.
Not every modern invention is right for every place where it’s employed.
