The Guinness World Records reports that freediver Aleix Segura Vendrell currently (as of March 2018) holds the world record for breath holding, clocking in at a mind-numbing 24 minutes, 3:45 seconds on February 28, 2016.

That busted other previous records, such as magician David Blaine’s impressive 17 minute breath hold. Amazing details on Blaine’s feat are available in this TED Talk

All very nice. But bioengineering will allow us to push the record up—possibily, way up. Some techniques, like “lung packing,” are already being put to use by daredevils. Per Deadspin:

This [lung packing] consists of inhaling the very largest breath possible, and then, without exhaling, puffing your cheeks full of more air and attempting to force that air down into your lungs. You are literally stretching out your lungs so that they can hold more air.

More exotic ideas, like the so-called “Aquaman Crystal” are promising.

Some extreme atheletes and freedivers are no doubt experimenting and pushing the limits.

And there are documented cases on the record of people surviving without oxygen for long periods of time. As the BBC reports:

When US toddler Michelle Funk fell into an icy stream in 1986, she survived an estimated 66 minutes underwater, preserved by deep hypothermia that reduced her metabolic rate to almost nothing.

Funk’s case was a freak accident. But by 2025 will a person voluntarily hold his or her breath for more than 30 minutes? (The attempt must comply with Guinness Record standards.)
