I learned a new word today, from this 1993 book on free speech: bluenose. A bluenose is a ‘person who advocates a rigorous moral code’ (Merriam Webster). They are the puritans of the past and the social justice warriors of 2018. Coincidentally I also came across an article about how lying freezes your nose: Researchers at the University of Granada found that when a person lies, “the temperature of the tip of the nose drops between 0.6 and 1.2 ºC, while that of the forehead rises between 0.6 and 1.5 ºC.”
