good one.

Some tips from a Northerner.

I converted a boxroom into a study. With the door closed, body heat plus a laptop can keep the temperature up. Running the Climateprediction.net program will increase your electricity bill, but increases the laptop processor temperature, which vents to the room, while doing useful climate science. Borrow your friend's dog, and that's about 180 watts in a confined space.

Insulated mugs. Enough said.

When making dinner, use your plate as a lid on the pan. The food cooks more efficiently and the warm plate keeps the food warmer for longer. Just remember to wipe the bottom of the plate before you use it, or your nice puffa jacket will need a wash.

For guys: grow a beard like mine.

Finally, your public library probably has free wifi. They heat the place anyway. You might as well use it.

What an interesting tip about the water Bill. I've never heard that before. By dry air, do you just mean a clear day?

I do have a lot of hair, so I think that I can get away without a hat indoors but agree that out of doors, it's essential in the winter months. 

I wear pretty much what I wore last year and the year before ...

For example, for a bit of extra warmth when it is chilly in the apartment or outside, I have a very nice insulated vest that my first wife sewed for me from a Frostline kit in the fall of 1977. I also have a black wool stocking cap that I bought new about 15 years ago. I put it on when a need a little extra warmth. The brain is a major energy consumer and a lot of body heat is lost through the head and neck. Hydration is important in the winter. Cold air is dry air. People lose a lot of water through their lungs in dry air. People tend to think that they are not thirsty if they are not hot. Remember to drink water, particularly if you are outside in the cold. A 10% reduction in the body hydration can cut your metabolic efficiency (ability to generate heat inside the body) by up to 90%, or so I long ago read somewhere. As a Scoutmaster in Alaska in the winter, I more than once treated a young Boy Scout with borderline hypothermia just by having him drink some water.
