It is true that the eye could tell a lot about our body. One of my friend was told that he would have some indigestion problem by one of his cousins just by looking into his eyes as he was practising iridology and was challenged to do so. To our surprise he was right. Though we could not believe him at that time but I still remember the incident. I think that such revelations aren't exact most of the times there are some exceptions to it too but we cannot dismiss it either.
