We didn't have money when I was little, so 55 was where the thermostat lived all winter (except at night, when it was lower) so that's probably where I get my "cold, you can adapt to" winter preference. Heat makes me want to die immediately, but God made hats and fingerless gloves for a reason.
Indeed. (Though having lived through too many frozen and burst pipes, and knowing how much more expensive that is than a few more kilowatt hours, I would not be able to consider dropping the thermostat at night. That’s just playing russian roulette with your pipes.)
I'll see if mom remembers, but I think the night temp was 50.
And the SNUGGIE is positively luxurious. Reminds me a lot of the kotatsu in other ways, in that it means you kind of pick a spot and stay in it most of the time. If I wanted to truly live the life of riley I'd look into that other essential Japanese invention. the heated toilet seat. :D
