"When you hear hoofbeats,
think of
horses, not zebras"
--Dr. Theodore Woodward
Description: A very highly experienced diver descends, making no evident attempt to stop the descent or any real movement of any kind, until she disappears from view in the depths.
Background facts: In the annual DAN fatality reports, the highest percentage of fatalities by far are associated with cardiac events. In most years, they are roughly 40% of all casualties.
Sudden cardiac death is the number one cause of death in the United States.
Comment: A person suffering from sudden cardiac death at the beginning of a descent wold continue to descend without movement until reaching the bottom.
I am having a hard time understanding this search for the
zebras highly unusual causes of death in this situation.
