0F .. 100F is about the range of temperatures a human living on earth could reasonably expect to experience without deliberate adventuring. It's not a precise range - plenty of people live in Doha (way above 100F) and in Alberta (way below 0F) - but it's a pretty reasonable approximation.

I'm not convinced the people of Doha or Alberta would consider their day to day lives adventures

My comment ends with a note that "it's a reasonable approximation".

The percentage of global population where the 0F..100F range is not a reasonable approximation of the temperature range they will experience is small. It's not perfect - no such range could, when humans live almost everywhere on the planet. But it's not bad ...
