It's cold here

Why is it so hard to feel warm when the thermostat says 70 degrees and it's gray with a light freezing rain and no sun outside. On a sunny day, 70 degrees on the thremostat feel almost too warm. I've come to the conclusion that I'm a true "Southern Belle" and need the sun to really feel good. A complicating factor is that the GI doctor told me to not take asprin, Ibuprophen, or Naproxen until next month when I see him again. I can only take Tylenol for the arthritis pain and my joints are really complaining. At least I can climb in my cozy bed and turn the electric blanket on high and thaw out. I think that's where I'm going.
