...hospital uses laughing gas for oxygen...
Conditions outside the cells in the courthouses were almost as grim. From criminal court in Brooklyn, TIME'S Paul Witteman reported: "The smell of vomit permeated the lobby. There were puddles of urine on the floor. In one corner, a Hispanic woman shrieked uncontrollably. Court officers administered oxygen to two women who had been felled by the heat and the strain of not knowing what had happened to relatives locked up in the cells. Police broke up a group of people being interviewed by a radio reporter. In the midst of the shouting and shoving, one man was arrested...
...trip wore on, Rosalynn was increasingly taxed - both mentally and physically. In Quito, the 9,350-ft.-high capital of Ecuador, she needed two doses of oxygen to get over the effects of the altitude. She calmly informed members of the ruling military triumvirate that the U.S. was not likely to lift trade restrictions imposed after Ecuador raised its oil prices along with other OPEC members...
OZONE DESTRUCTION. The layer of ozone, a highly reactive form of oxygen, in the stratosphere absorbs much of the ultraviolet radiation from the sun, protecting humans and other organisms from an overdose of these solar rays. But the layer is fragile, susceptible to a number of chemicals that convert ozone back into ordinary oxygen. According to the U.N. report, the widespread use of fluorocarbons as propellants for aerosol spray deodorants and other products may have already depleted the ozone layer by 1%, and could cut it by as much as 10% by the year 2050 unless the use of fluorocarbons...
...basis of Cooper's system is his use, as a measure of conditioning, of the amount of oxygen a circulatory system can take in and use in a given time. This he measured by positioning runners on treadmills and capturing their exhalations in plastic bags. The more oxygen used, the more work done before exhaustion, the better the subject's condition. Cooper found that he could approximate such tests by measuring the distance a runner could cover in twelve minutes over a track-1% miles for a man under 30 in excellent condition: 1.1 to 1.24 miles...
