Hell, I keep mine at 66° in the winter, if they do that I might just turn it up to 69° or 70°.
Brrrrr! I get cold if the temp is below 70 degrees. LOL! My comfort range is narrow - - 70 degrees to 80. Outside that, I'm too cold or too warm
We keep it around 78 degrees in the house during the summer. The A/C is more to cut the humidity than anything.
