Select few redefine human abilities

CNN.com - Select few redefine human abilities - May 3, 2004

Very good article in CNN about people who have extraordinary physical abilities such as greater than normal lung volume or capacity and muscular strength. One woman, a champion free diver, has the ability to survive very low oxygen levels in her blood (a normal lower limit is 70%, she goes under 50%). As a result, she can old her breath for over six minutes.

I'm in awe. With training, and in my 20's, I could hold my breath for two minutes. Most couch potatoes can't manage one minute!
