Indeed. One of the things you learn in physical anthropology is that one of the things that separates humanity from other primates, physically speaking, is our ability to go underwater. We have an innate "shut off" valve, as it were, that stops us from inhaling water as a reflex action upon submersion. Apes and other primates don't.
Sometimes that does not work. The problem is that even a small amount of water that is inhaled into the lungs can kill you.See the following advisory:
"Infants and Toddlers at Risk of Drowning in Bathtubs, Spas and Buckets
80 percent of deaths involve children younger than two
WASHINGTON, D.C. - When pool season ends, many parents believe the risk of drowning also ends, but data from the U.S. Consumer Product Safety Commission (CPSC) released today indicates 311 reported non-pool drownings from 2002 through 2004 of children younger than five years of age. More than 80 percent of these deaths involved children younger than two years old. The pattern is much different than that observed in pool-related incidents where children younger than two accounted for 38 percent of deaths (involving children younger than five).
Bathtubs were involved in most (71 percent) of the non-pool drowning deaths from 2002-2004. Many of these incidents involved caregivers leaving the room to answer the phone/door or to retrieve an item. In some incidents, an older sibling was left to watch a younger sibling.
"Infants and toddlers need particularly close supervision," said CPSC Acting Chairman Nancy Nord. "Drowning can occur within seconds in only inches of water, so parents need think of, not just the pool, but any water anywhere as dangerous
CPSC recommends parents and caregivers follow these safety tips when children are around bathtubs, spas, buckets, or decorative ponds or fountains:
* Never leave young children alone near any water. Young children can drown in even small amounts of water.
* Always keep a young child within arm's reach in a bathtub. Never leave to answer the phone, answer the door, get a towel or for any other reason. If you must leave, take the child with you.
* Don't leave a baby or toddler in a bathtub under the care of another young child.
* Never leave a bucket containing even a small amount of liquid unattended. Toddlers can fall headfirst into buckets and drown. After using a bucket, always empty and store it where young children cannot reach it. Buckets left outside can collect rainwater and are a hazard.
* Prevent children from gaining access to spas or hot tubs when not in use; always secure with safety covers and barriers.
* Learn CPR (cardiopulmonary resuscitation). It can be a lifesaver when seconds count."
While the YouTube video is not of good enough quality, it does seem that the Priest dunked the baby headfirst three times but very quickly between the dunks. If you think about it, the first reflex after one rises up from water is to breathe; in this case, the poor baby may have been dunked again too quickly, while he was inhaling. Head first, by the way, may be the most dangerous way to dunk somebody as water naturally goes into the mouth and nasal cavity and has little chance to drain out by itself (that is why divers blow out the water and air before they inhale air). Anyway, horrible tragedy.
