In the New York Times article Chilled by Choice, writer Penelope Green interviews a number of people across the country living in cold climates (such as New York and Colorado) who choose to live in a home with no heating. In the Winter. Many of these folks' homes are an average of 30 to 40 degrees in the Winter, and they point to a number of reasons for their choice to live without heat.
I have a very hard time imagining that I could handle these temperatures, and I definitely don't want to wash dishes in a down jacket, or rig my toilet so it runs constantly, thus preventing frozen pipes, as these folks do. Still, I admire the pioneer spirit of these cold-weather-embracing dwellers. I just don't think I want to be one of them.
