You cannot win this one. For 30 years my wife had low blood pressure and anything less than 80 degrees gave her frostbite....summer or winter. Now she has gained a few pounds and developed high blood pressure, and anything over 72 is a heat wave. We can pretty much agree on winter thermostat settings, but summer central A/C settings are not so agreeable. It's like walking into a meat cooler.
Me too, me too. Just wear long pants and a sweatshirt. In the long run its more comfortable then fighting over the temp.
