I’ve tried picking up people and shaking them, but they don’t rattle. So if it is Lego, then it’s been put together really well. But if it isn’t Lego, then I’d like to discover what makes us so special as individuals. I’ve got a couple of books on genetics, and it seems a very fascinating subject. I’d like to know what I need to do to be able to study it properly, and perhaps make it my career.
