Video: Into the abyss
Some videos take your breath away because they are so stunning/picturesque/awesome. This one's all of the above, but it will take your breath away for an entirely different reason: just how long can this dude hold his breath?
Filmed at Dean's Blue Hole - the deepest blue hole in the world, measuring 202 metres to the bottom floor - world champion freediver Guillaume Nery jumps in and holds his breath as he makes his way to the bottom and back.
I think he must have a spare lung hidden away somewhere.
