I think the phrase "some people" is often used as code for "everyone who is reading this." I'm thinking quite a lot of other stuff too, but if I write all of it in this post, "some people" might feel that their own mental processes are inadequate in comparison. If you, gentle reader, take offence at this idea, this proves the contention made in the first sentence.
P.S. This is my idea of a joke. If you don't find it funny, it means your sense of humour is not as twisted, or maybe just different from mine.
