Went to the dermatologist today to get some skin lesions zapped with liquid nitrogen. It was cool. I asked the doctor if anyone has ever asked him whether nitrogen is dangerous. To my surprise, he said no one has. He thought it was funny that there are actually people who assume nitrogen is a dangerous pollutant, or a deadly “chemical.”
(Sneer quotes because woowoos define “chemical” as “stuff that is dangerous” to humans.)
