Like Mom (and MOM), I have Reynauds. So I'm usually cold way before anyone else is. And, thanks to a recent bout of mono (Yes, I know, mono in your 40s is very embarrassing. Can we not talk about it any more?), I need to be careful about catching colds and viri and all - and let's not forget that working in a school = working in a germ factory.
This is the first year I have to pay for my own heat. I've been diligently following the news and it's going to be expensive. So I set my termostat so that when I was up and puttering, it'd be 65; 60 when I wasn't. It got really cold, which is odd because it should feel warm at 60 when it's in the 40s outside. But it doesn't and I'm not science-minded enough to understand why.
Anyway, last night, my mother insisted that I move the temp. to 68 when I'm up and about, 65 when I'm not.
If I go broke paying for this... Still, I suppose it'll offset my support of all the cold remedy companies...
ETA: walking into my 68 degree cottage was pretty nice; oddly enough, the bedroom hasn't warmed up yet. If it ever will. Still, I have my flannel 'jammies and sheets and two comforters to keep me warm!
