My wife is the same. She goes by the thermometer. If it is in the 20s outside she is cold until the house is in the 73-75 range. That's too hot for me, but we compromise. It's been 74º in the living room all week during the current cold snap.I'd love to have our house at 71. As soon as stove weather is here the wife demands 75 to 78 in the main living area! I wear shorts and a tee shirt all winter and she is still in flannel with a blanket. Lol. Funny thing is is that before we bought this house and got indoor wood heat we never let the previous house get warmer than 70 and the night time set back was 64. Never a complaint from her.
