Inside Edition, that bastian of hard news,  has taped a segment at the McCoy Natatorium about, get this, people who drown while holding their breath. They're interviewing Tom Griffiths, an aquatic safety expert on the subject. I can't imagine the interview not sounding exactly like this:

Inside Edition: Is it true millions of people a year drown in swimming pools?
Tom Griffiths: Well, no. Not even close to that number.
IE: But you agree that swimming pools are a lurking danger that pose a threat to every oxygen enjoying person.
TG: Yes, I would say that people underestimate the lack of oxygen that exists under water, thus contributing to many drownings in the U.S.
IE: You heard it here folks. Every pool in America is a death trap. Back to you.

Not breathing:  the deadlier side of respiration.
