There is something noble and pioneering about the sport of freediving.
Mavericks and free spirits pushing their minds and bodies to the edge of human endurance and beyond while the rest of us stay within our comfort zones.
It is a solitary sport which requires much courage and determination to push through into dark unknown depths.
These are two qualities that former Havelock North High School student and current world-record freediver William Trubridge has in abundance and he will need them tomorrow morning when he attempts to break his own current record of 101 metres for an unassisted freedive.
Clearly the sport holds a magical appeal for Trubridge who has said: "The fact we're completely immersed in liquid; a single breath, the weightlessness, the absence of sounds, the dullness of the colours ... everything is subtracted."
