Just take your work and Duvet to Alaska, The Yukon, Siberia, Greenland, Antarctica/The Arctic, or any other geographically frigid climate, and you'll be just fine...with all the ice cream you could ever want AND no possible way to be WAY to warm...ever. ^_^
When you go, send a post card...
You know...one of the benefits later in life is that they don't have 'hot flashes' in places like that... Just 'warm moments' before the cold sets back in. ^_~
