Thats Deep!

Sara Campbell, a British freediver has set a new record by diving 314ft on one breath of air.  Thats crazy.  My ears pop when I swim 10 ft under water and i really do enjoy swimming.  She is only 4 foot 11 and dives with nothing but a mermaid like fin on her legs.  over a football field deep while holding her breath with no extra weight.  Free diving seems like a very strange sport to me and very dangerous.  If you pass out you die and the goal is to push yourself as close to that as possible.  I know people like to push limits but that does seem strange to me.
