I'm virtually ALWAYS cold. Seriously, it can be summer, and I'll be cold. I've learned to adapt by wearing warm clothes, investing in good slippers, and always having blankets around.
My dear brother in law knows this and got me a wonderful snuggie type blanket for Christmas.
Ironically, our friend who keeps his house at 60 F was cold at our place the other night.
So we bundled him up!
