How cold do you keep your house in winter and summer?

Yes we have been having some crazy weather here in Atl. I keep my home during the winter nite-62,63 & day-65-67. The heat dries me out too much so now I really can't being indoors with the heat going full blast. During summer& mostly cuz my system is now 30yr old I keep the temp about 80, 81. I would do a lil lower if I could but too expensive for air to run all the time.
