Time was, I was always too warm or warm when everyone else was cold. Now I seem to be perpetually cold. I've even put on the furnace when the temperature is in the 50s. And I have to set my thermostat higher than 70 degrees on really cold days -- sometimes up to 75. Why? Age, a wonky thyroid, medications, maybe all of the above. Who knows?
Such is life. Just have to deal with it.
