Wow 66. The parents in the strip I think are in their 40’s. I found sometime in my 40’s and maybe even late 30’s I seemed to get colder easier year after year. Our temp is set to 69 which is partially because I find it funny but does just work. My wife is always cold and we have had a lot of conversations around this topic. My rule I will not budge on is that we should be colder in the winter and hotter in the summer. I have known so many folks that want their house 70 when its 100 degrees outside but 74 when its 0 degrees outside. Which is just nuts to me. 69 is basically a bit cold for us but it works with blankets and our heating system is electric so in the daytime we use portable heaters actually to feel comfortable in the space we are in. Bathrooms can be cold and we hope to get in floor heating. I sorta wonder if they have radiant heat as when we have had it we found lower temps felt more comfortable than our forced air system.
