I think my AC is set for 72*F. I'd probably have it lower if I weren't paying for electricity.We keep our air conditioning on 74/75 Anything below 70 (indoors) is absolutely frigid to me.
Yes, BUT, there are only so many clothes you can put on before you can't move, lol.You can always put on more clothes if you get cold but can only legally take off so much in the summer.
