There are some things I just can't get my head around and here are two of them. I think I sort of maybe have some of the answers, but they are very nebulous in my head and I certainly can't put it into words. Can you help explain? Firstly I don't understand fashion. Not so much our having to preen ourselves in public and stand out visually. I assume that is really about attraction of the opposite sex for our continued procreation. No, -- but how does fashion work? Who sets new fashions? And why/how do they catch on? Looking back over my lifetime, fashion which was attractive at the time now looks absolutely silly. Why? I cite 70's mullets and 60's flared jeans. Secondly what is art? Not so much about the art itself but the obscene values we put on some of it. I suppose art is art (to coin a phrase) but why do we allow people have more money than sense to hoover it up and hide it away from the rest of us. Presumably the artist had something they wanted to say to as many people as possible, who would listen? So -- is there anything you don't understand and want help with?
