I'm getting more and more data points to suggest that one of the truths of retirement is that you keep your housing at the same temperature as your age.

It seems like everyone I know in their late 50s and early 60s keeps their house at a temperature that would make penguins go searching for a fleece pullover.

It gets better when those in question reach their 70s. But by the time these folks are 80 and 90 years old, the temperature of their apartments rival the dry sauna at my local gym.

I look forward to the memo that explains all this as I get on in years. So many rules I'll have to learn!
