You’ve likely heard that we can live weeks without food, days without water, but only minutes without oxygen—unless, of course, your brain is cold. In Argentina, when a baby born three months prematurely was pronounced dead by two doctors, her tiny coffin was placed in a morgue refrigerator. That night, with mother’s insistence, her father pried open the box of death. The baby was alive! Cold had reduced the need for oxygen and saved her life.Air without life-giving oxygen is like a tire without air—flat. Air is a gaseous ocean for life. No air, no life.
