With my wife? 68 degrees. With me? Never. Funny though, she will go to bed with a pile of blankets wool socks and my still warm hand warmers. If I get up about 1am there will be an orange glow from her side of the bed. But by 2am she has kicked all the covers off and over top of mine and have the window cracked and the fan on high. I usually end up with a form of jungle rot by morning from the heat she is putting off plus 6 layers of blankies!
