mystery solved

Where are all the fourth floors?
This question has been lingering ever since my parents were here. Every hotel we were in had no fourth floor, or any rooms with the number four in it. Why?
The best answer I could get for the inexplicable amnesty on the poor number was superstition. But there had to be more to it than that surely. And then today, someone finally told me.
Turns out the word for four in Chinese (s) is the same as that for death. Add that to a very superstitious culture and vlwala, no fourth floor. This is where the dead live, so in hospitals they figured they may as well but the morgue on the fourth floor since everyone's dead already.
Other than collecting more useless knowledge I went on what is starting to seem like a never ending search for a video camera. They have ones you can loan out, but you can't book them in advance and there's no time limit on how long you take one out, so people just don't return them. I'm starting to wonder if they really exist.
Maybe they got lost on the fourth floor.
