There's something about Mary's eyes...

I read on one of the Indian internal airlines (SpiceJet I think) about 'Indian dating customs'. How you can tell from people's eyes whether they are any good or not, if there is white showing above the iris it means that they are unhealthy, if there is white below the iris it means they are stressed and liable to snap, if there is white showing both above and below the iris it means they are total psychos, and you should run away straight away!!
