Some people are just f**king stupid. For your health you're much better dressing properly than living in an over-warm house. I wear arthritis gloves due to very, very low Raynauld on my hands. No need for a baking hot office.
Heating in the 60's? No fireplace in my bedroom, ice on the north-facing windows, maybe one fire running in the house before heading off to primary school in Ramsey. I do not remember KWC being over warm in winter. We turned out normal (*).
* YMMV.
