Have you heard of a game teens are playing by hanging themselves until they p out but not suicide?

A neighbor's 15 year old granddaughter was playing this game, they said on the news that teens are into this game. My neighbors granddaughter was burried today. She was alone! If these kids are going to be playing the chocking game why not do it whith someone else in the room to save you?Why do these kids play thes very dangerous games! Now this short life was cut short and for nothing!
