Today: holding your breath. It's not something I keep in my mind, the matter of how long those insane free divers can hold their breath.
So, from a story about them at the ABC:
The current men's world record holder is Stephane Mifsud of France with a time of 11 minutes and 35 seconds and the womens' world record is held by Natalia Molchanova of Russia with a static breath hold of just over nine minutes.The sport doesn't allow pre-breathing of oxygen, I believe, but for divers who do that they can get up to 20 to 30 minutes, it seems.
The claim that Cruise once held his breath underwater on set for 6 minutes is therefore not completely ridiculous, after all.
Update: Oh. The female champion diver I mentioned here has been claimed by her nutty hobby.
