"Nineteen-year-old Singh has been eating sand for the last sixteen years.
His friends didn't believe when he told them about his eerie habit.
"One day my friends and me decided to eat sand. Then I ate sand I found it to be very delicious. I started eating 500 grams everyday and now I enjoy it," said Singh.
This may be a simple thing for Kulwinder but his parents are worried about their son's unusual behaviour. But says they are helpless as he never listens."
he started eating sand at 3 and they,his parents, were powerless to correct his behavior???
