Zero > But it DOES occur in everyday life. There are zero fish in this >room right now (and that's been the case for every day that I can >remember).
My philosophy is different: Either exists a fish in a place or not. I count only existing things. A fish in John's room is a not existing thing; therefore I don't count it. (being 5 fish and having to count them: I don't count as 0,1,2,3,4,5, fish but as 1,2,3,4,5)
Now, John, enjoy some stories on zero from math/ans everyday life :-))

"When I was young in Poland I met the great mathematician Waclaw Sierpinski. He was old already then and rather absent-minded. Once he had to move to a new place for some reason. His wife wife didn't trust him very much, so when they stood down on the street with all their things, she said: - Now, you stand here and watch our ten trunks, while I go and get a taxi. She left and left him there, eyes somewhat glazed and humming absently. Some minutes later she returned, presumably having called for a taxi. Says Mr. Sierpinski (possibly with a glint in his eye): - I thought you said there were ten trunks, but I've only counted to nine. - No, they're TEN! - No, count them: 0, 1, 2, ..." (From the Net)
