This gives me "who can stare at the sun the longest" vibes.

Sure this might have some practical applications, but I wonder about the long term side effects

aside from harvesting stuff from the seafloor i can't think of any situation where holding your breath for more than 5 minutes is particularly helpful

but on the flipside being able to hold my breath for 5 minutes would be real neat

I mean, for spear fishing or doing literally anything under water it's very helpful. I have a friend who regularly spear fishes and it's very important that he can spend a long time at the ocean floor without moving so he can catch fish off guard.

Wait, how is that possible? Doesn't the brain start dying from lack of oxygen after about 5 minutes?

you're thinking of like, being choked, i presume. the difference is that choking directly cuts off bloodflow to the brain, but if the bloodflow isn't disturbed then there's a decent bit of oxygen stored in the air in the lungs and in the blood itself.

this is how animals like whales can dive for hours at a time, they store oxygen in their blood.

The thing that actually makes you feel the need to take a breath is buildup of CO2, not lack of oxygen. My understanding is that holding your breath isn't really about the amount of oxygen you have but rather how long you can resist the urge to breathe, though presumably at these extremes they do have to pay attention to how they feel and abort if they start feeling tired or whatever low oxygen does to you.

Don't be fooled!

I tried to meet this guy for an autograph, stood in line for ages, and when it was my turn do you know what this record holder said, for a simple autograph???
He said, "I'm gonna need about tree fiddy."

That's when I noticed this breath holder was about 50ft tall and from the protozoic era!

I haven't seen this one in the wild for quite some time. Brings back memories.

Here's the translated Croatian article:

An incredible Guinness World Record was set in Opatija – Vitomir Maričić held his breath for an astonishing 29 minutes and 3 seconds, leaving both the audience and experts amazed. This is one of the most demanding records, lying at the intersection of sports, medicine, and science.

The record dive was performed after several minutes of preparation and breathing pure oxygen. The entire attempt was monitored by five judges and an official team to ensure the result was valid according to Guinness rules.

"Today it was really hard for me to dive; yesterday it was easier, but after the 20th minute, everything became easier – at least mentally," said Maričić.

The feat is part of the Fit for the Ocean campaign, which raises funds for the organization Sea Shepherd, known for its fight against illegal fishing. Maričić used the opportunity to highlight the importance of ocean conservation and the need for informed action from all of us.

Damn. My brother literally just met the previous record holder last week.
