Very interesting! I didn’t know all of them, but it is nice to learn new things. Usually we take everything for granted, without asking too many questions.

I shivered uncontrollably right after labor/delivery (...many years ago, but I remember!) and also after major surgery and when I had a bad flu. BUT also when I was sweaty & cold from exertion in snowy weather.
