Little Rishi (a student of class VI) was watching his favourite cartoon serial on television, while eating lunch. Suddenly he started getting hiccups. His elder brother Shubham, who was sitting near by him, gave him a glass of water and suggested not to eat too fast in a hurry. Little Rishi got confused as he had heard that 'hichki' comes when someone remembers.
He asked his father. His father smiled and explained him that it is only a myth. He also explained him the proper scientific reason behind it.
