Don't know how old you guys all are..... but at some point the thermostat in the wife is going to go apeshid. Whether she was always chilly or not before, she will go from bathing in sweat in January in a cold house to chilled to the bone in a July heatwave....
There is NO WAY to mechanically deal with this even if you wanted to.....
It goes away eventually, but in the meantime....strap in.
