I stumbled upon this gem of a video.
Knowing how hard it is to hold your breath and cool whilst being submerged for four minutesmakes me respect this man deeply.
There is a lot of physical training and talent involved, but in the end, this is pure willpower in action. Training your mind and body to ignore the sense of drowning and slowly push the boundary further every time you do this.
And I'm really in love with the grace (and music) at the end of the ascent, as the light filters down more and more and more other divers join him for the last leg of a truly epic dive. These things make me happy to be alive.
