Shaula EvansI've just gone down a fascinating rabbit hole (as one does)!
In The Vengeance of An, a character mentions that someone else habitually chews on bitter herbs, because people in the North do that to stay warm.
So I looked it up (of course!) and there’s growing evidence that some bitter compounds can stimulate thermogenesis, the process by which your body generates heat and burns calories. This is so cool! 1/n
