Eating glass, stone. Drinking Acids, pesticides

I was surprised to read in a newspaper that some one named Ashok eats stone, glass etc everyday and can even drink acids and pesticides which can easily kill a normal human being. He has claimed that he eats normal meal only once a day and for the other meal he prefers these items!

Ashok ate a think glass bottle infront of the news reporter to prove it.

He is even ready to co-operate with doctors to find out how he is able to digest these things.

After much searching on the net to see if I can get more info or links found this one.
