Other doors and walls are not rated, though the construction of most walls isn't terribly different from a rated wall - a gyp studwall. Where you lose the rating is penetrations aren't protected, so it's easy for fire to bypass the assembly.

It's not that you run down the stairs so much as a controlled shuffle. The whole point of the fire rating is to give people time, so no need to rush and potentially hurt yourself.

Yeah, it can be a pain when the fire alarm goes off at 3am and you're 40 stories up, but ultimately all of this stuff exists because people died. Take advantage of all the things that make modern buildings safer.
