Hans Raj from Uttar Pradesh in India has been eating sand everyday for the last twenty-five years due to which he has been nicknamed Sandman. Not just this, the 45-year-old feasts on bricks as well. Despite his intake of hard substances, his teeth remain sharp and void of problems. He gives the credit for his fitness to the minerals he consumes via sand and bricks, sometimes going so far as to add these substances to tea, bread and soup. However, doctors believe that he suffers from an eating disorder called Pica, which causes the individual to consume non-edible objects.
