Eli5: I’m from Florida, where its very hot. My friend is from Alaska, where its often very cold. Today it’s 60° out, and it feels a little chilly to me, but my friend says its still warm.
Heat is a discretely measurable property. You can’t measure cold with a thermometer. But this is true of many things. You can measure caloric intake, but you can’t measure hunger or fullness. You can measure hours of sleep, you can’t measure tiredness.
