I grew up in the pre A/C era. Society was definitely more 'social' then. you knew all of your neighbors within 3 or 4 blocks. Allergies were rare. My family never did install A/C and I have not used it myself since. Your body adjusts to seasonal changes as it was meant to do. And, bcg, we have had triple digit heat indexes here in the Florida Panhandle for the past month. Last week it got to 113 and has been reaching 105-110 most every day. I use an electric fan. No A/c for me!
