Interesting article OP; thanks for sharing! I can remember about 15 years ago I took a college course in adaptive biology in mammals and this topic
was discussed while on the topic of aquatic mammals. Although, it was only theory at the time. Anyhow, there is another mechanism that allows the body
to go longer on less oxygen; it is called the dive reflex. Incidentally, it is also the dive reflex that allows drowning victims to be "brought back
to life" after being submerged in cold water for extended periods of time.
A fun little experiment that anyone can do at home, and is especially fun as a party trick or to get kids interested in science, is to get a large
bowl of ice water, check your heart rate (pulse rate) and then submerge your face into the ice water. Immediately upon your face touching the ice
water, your heart rate will drop significantly....if someone does not believe you, then place a friendly wager on it.
