Age certificates - for books
Does anyone else sometimes wish books came with age certificates like movies do?
When I was younger I read all sorts of unsuitable books, half without realising it when I was too young for the content. There were also the ones I knew were bad but read anyway but that's a different story.
I think this is especially true for early teens when you get fed up reading about talking lions and want something more that isn't a serial teen drama called "my big ugly knickers and other traumas of being twelve" or something like that. So you go and read American Psycho because it looks interesting and then don't sleep for two years.
Just wondering what other people think, could it work? Would it just encourage young people to read the wrong stuff anyway, waving a big tantalising "you're not supposed to read this" flag above them? Is the kids, young adult and other sections in bookstores/ libraries enough?
