this late stage of my life) but rather it's about implementing a
"minimalist" life style because that's what I believe in.

I like a minimalist life style. It not only saves money, but is good
to your mental health as well. I believe, everything being equal, a
person demanding less lives a longer life.

The reason I asked the question in this thread is because I was
wondering if using the house heater would save me more (looks like
not). I work from home a few days a week. Kids and wife are all gone
during the day. So I want to heat my own body only. But as others
remind me, I won't let the house stay too cold causing damage to the
floor, etc.
