Just read an amazing story

I had never even heard of this competition. This woman is superb -- more or less superhuman.

Site creator sorely lacking in communication skills.

Got to the whizzy-dizzy one after she submerged her dolls and finally inferred that this was just another Evel Knievel contest, where you try to get as close to dying as possible without actually croaking, and clicked out.

Y' know, Houdini damned near drowned while doing his upside-down submerged escape stunt. The best-laid plans of mice an men go oft awry.*

I would like a linear 50-word executive summary.

"I would like a linear 50-word executive summary."

Woman sad. Woman contemplate suicide. Woman dives deep and finds new purpose.

There you go. 12 words.

What the human body can do with training is really amazing. When I was diving all the time at work, I could do 3 minutes, non-exertion. I just now tried it cold after not training for years and got 1.75 minutes. I could probably still get back to 3 minutes, but not much farther.

I read that Tom Cruise got to 6.5 minutes for his role in Mission Impossible. The static apnea record is almost 12 minutes. Interestingly, with pre-dive oxygen, that goes to 24 minutes. I can't even imagine 24 minutes without breathing.

Thanks for the 12 words, K Frame.  I set 50 as a maximum.  My executive comment would be "If that's her new purpose in life she should re-examine that life anyhow sans suicidal tendencies."

I'm kind of curious what effect altitude might have on that (apart from pre-saturation with pure O₂).  If the blood is saturated with O₂) at high altitude, is that any different from saturation at low altitude?  At sea level the partial pressure of O₂) is 152 Torr, at my house near Golden CO, it's only about 132 Torr.

And how much does trained acclimation to the need to get rid of CO₂) count in all this? (As I understand it, it's the need to get rid of CO₂) which drives the need to breathe.)

As I recall, as a teeny-bopper, before I started to smoke, I could do a little over 2 minutes (sea level). Of course, that was New York City "air".

Little judgy mcjudgy face, don't you think?

When I was a kid, a couple of summers we had pool memberships.

Some of us used to go sit on the bottom and see how long it would take to get the lifeguard to come after us.

Well, aren't you all McJudgy-face now, aren't you?

[K Frame]

Well, aren't you all McJudgy-face now, aren't you?

I make absolutely NO pretense about it. I'm a busy person. I pass judgement and I move on.

[230RN]

Ah, yes, the executive comment.  Looks like we're on the same page.
