Winter warmth? What do you leave your thermostate on within the winter months? ...

What do you leave your thermostate on within the winter months? An average? I know it is suggested to put in between 68-70 for affordable billing purposes, but we head off ours on 72, just so to be precise will be warm. Do you consider 68-70 is an unreasonable temp to leave your thermostate on?
Answers:    If you hang on to the home high surrounded by humidity it will seem stove. Pot of water on the stove or run the shower on hot beside the door open for a while.
WHEN WE ARE NOT AT HOME THE TEMP IS SET AT 62 AND AT 5:00PM IT TURNS ON AT 66. AT 11:00 PM IT GOES BACK TO 62 FOR THE NIGHT AND AT 5:30AM BACK UP TO 64. WITH THE PRICE OF FUEL TODAY I THINK WEARING A SWEATER OR SWEAT SHIRT HELPS TO STAY WARM UNLESS YOU ARE ELDERLY OR HAVE SMALL CHILDREN I SUGGEST TURNING IT DOWN A COUPLE OF DEGREES
