That is how they spar

Kind of, but not really. 0F doesn’t mean anything special in relation to human interaction, it relates to the freezing point of some random salt and water mixture (not seawater). 32 is a random number for the freezing point of freshwater which humans do care about, and 212 is nonsense for boiling temp of water which humans also care about and routinely use. The only part pertinent is that 100 is close to, but higher than human body temperature, but not quite where it counts as a fever… just the temperature of a sub-feverish human… how is that helpful! Sorry I really don’t care for the Fahrenheit system and I’m prepared to die on this hill
