It certainly IS doable to live in the south without air conditioning as I can personally attest to. I grew up on the coast of Florida and we didn't have air conditioning until I was a teenager. It was helpful to have an attic fan which pulled air through open windows. I do remember in school my clothing sticking to the varnish on the desk seat when I would go to stand up due to the heat melting the varnish. Doable, but certainly not ideal!!
