http://members.aol.com/Oldrope/breath.htm (excerpted from the same article by Jay Wiseman) "...The primary danger of suffocation play is that it is not a condition that gets worse over time (regarding the heart, anyway, it does get worse over time regarding the brain). Rather, what happens is that the more the play is prolonged, the greater the odds that a cardiac arrest will occur. Sometimes even one minute of suffocation can cause this; sometimes even less. ... In addition to the primary danger of cardiac arrest, there is good evidence to document that there is a very real risk of cumulative brain damage if the practice is repeated often enough. In particular, laboratory studies of repeated brief interruption of blood flow to the brains of animals and studies of people with what's called "sleep apnea syndrome" (in which they stop breathing for up to two minutes while sleeping) document that cumulative brain damage does occur in such cases. There are many documented additional dangers. These include, but are _not_ limited to: rupture of the windpipe, fracture of the larynx, damage to the blood vessels in the neck, dislodging a fatty plaque in a neck artery which then travels to the brain and causes a stroke, damage to the cervical spine, seizures, airway obstruction by the tongue, and aspiration of vomitus. Additionally, there are documented cases in which the recipient appeared to fully recover but was found dead several hours later. ..."
