Is it possible to suffocate from voluntarily holding your own breath?
There was a news article, a few years back. A 64 year old woman threatened to hold her breath till she turned blue when police arrived. So she did, and she collapsed and had cardiac arrest. She was in critical condition for several days before she died.
A Greek Philosopher, named Zeno, was said to have committed suicide by holding his breath. Another philosopher, (his name began with an M..he was also greek I think) committed suicide by holding his breath.
MYTH - BUSTED!!
No scientific studies have tested people holding their breath - cause it ends in death! so u cannot say it isnt deadly.
