A Croatian freediver has achieved a seemingly impossible feat.
On June 14 of this year, Vitomir Maričić took one last gulp of pure oxygen and lay down in a pool. There he remained, cool as a sea cucumber, for 29 minutes and 3 seconds.
That's officially the longest held voluntary breath, according to Guinness World Records. Maričić beat the previous record holder by nearly 5 minutes.

To get as much oxygen into his body as it could possibly carry, Maričić inhaled pure oxygen for 10 minutes before the attempt.
