I wish there was information about who at Facebook received this information and “used” it. I suspect it was mixed in with 9 million other sources of information and no human at Facebook was even aware it was there.
I would expect an app with 150 million active users to trigger some kind of compliance review in Meta
Still impressive nonetheless and I didn't know that this trick is sometimes used in Hollywood to extend underwater filming time. Avatar 2 comes to mind when I was impressed to find out Sigourney Weaver trained to hold her breath for 6 and half minutes in her 70s!
Coming back to the article, I'm disappointed that the details were sparse - how do they check whether the contestant is conscious? How does the contestant know what his limits are before passing out?
already answered but they'll apply pressure on your hand (or similar) and you need to apply pressure back
> How does the contestant know what his limits are before passing out?
When you hold breath for a long time your body will have muscle contractions. The time that needs to pass for each contraction to happen varies from person to person but it is quite consistent for each person. So free divers can know that they are good up to X contractions which will take after X minutes in certain conditions. The fun part is you can train to experience your first contraction by holding your breath while laying down in bed.
