Chris Ivey sent me this video and article about Guillaume Néry, a daredevil, free-diver who descends to the bottom of the world’s deepest swimming pool without any breathing apparatus. The pool in Brussels, Belgium, is called the NEMO 33 and is 33 meters deep. It contains 2.5million litres of non-chlorinated spring water and is usually reserved for scuba drivers to train in.

For French-born Néry the dive would have been a welcome change from his usual escapades in harbours across the world. The constant-weight free-diving specialist broke the world record in 2002 by descending 87metres in the Villefranche-sur-Mer harbour, in Alpes-Maritimes, France. And in 2004, he plunged 96metres in Saint-Leu, la Réunion, before battering the record again in 2006 with a 109metre dive in Nice, France.

His feat has subsequently been beaten by two other divers, with Herbert Nitsch currently holding the title with 124metres.
