This is utterly mischevious news. I am saying this because anyone can die anywhere if he is suffering from ailment. Some may die while dong yoga if he is thinking of something back home and gets heart attack. Why does it become a news at all? If done correctly Yoga will not hurt. Even if one does minor mistakes performing assans- he/she will not die.
Sorry to say it looks like a MNC(pharma-cola)company news which will not deter any Yoga follower
