This is such a U.S. and Europe centric view of "outdoors" that I almost spit out my coffee. And probably a small part of U.S. and Europe at that. Ask people in the tropics or subtropical regions and they probably never experienced 0˚F in their whole life.
Originally the lower defining point, 0°F, was established as the freezing temperature of a solution of brine made from a mixture of water, ice, and ammonium chloride. That's just as arbitrary as defining 0˚C as the freezing point of water.
I don't mean that one small region hits 0-100˚F. That's not very common in the US or Europe either. But across all inhabited areas, 0-100˚F is pretty representative (again noting the sub-0 extremes where you're not going outside anyway). And say your area is just 60-100˚F, that's still decent, certainly better than a 22 degree range in Celsius.
