Do you find you're endlessly fascinated by this thing on the front of your head? Well you're not alone. We love faces, our own and other peoples. But why do faces interest us so much and how much do they really tell us about their owner? Like us, other animals are also fascinated by what they see in the mirror but unlike us they think they're looking at another animal. Only chimps, and of course, man can recognise their own reflection to know that what they see is who they are- well, the intelligent ones can do that anyway. Perhaps we pay too much attention to faces. My mother used to say, You can't tell a book from its cover So how much does this mug tell you about its owner? This is Vicky, a 21 year old student. Sometimes I'll think that, you know, I'm the hottest chick in town or something you know, I think, yeah I'm pretty, pretty cool I'm an OK babe, you know. And then it will be somebody's, somebody will give me a really bad look, and then I'll remember that I don't actually look that way. Vicky has a rare genetic disorder called cherubism and strangers can find her face unnerving. Some people will just look and then they'll glance away.
