Having too much of a “good thing” is usually not a fine thing, but excess ice cream, beer, plus extra helpings from your local buffet could come back to haunt you later, and you might believe that air is something that an abundance of could not possibly cause harm, however that is not the case with deep-sea divers. If they emerge too suddenly, they will end up with decompression sickness, known as “the bends” caused by a build-up of nitrogen in their blood. Air is about 74% nitrogen, an amount almost five times that of oxygen plus having too much oxygen also presents risks with oxygen toxicity. Ozone is an oxygen molecule with too much oxygen with the extra atom of oxygen connected to the molecule. It will disinfect, however it also can disfigure tissue. The only several things that the people I was with and I can “consume” in abundance separate from any danger are love, goodwill, plus air at sea level pressures. They all come separate from calories with care about plus goodwill available at no cost. With air, several conditions prevent it from being in the category of care about plus goodwill. The conditions are that the air must be wipe plus at the right humidity. All of us can’t control the outdoor air quality plus the only way to control it indoors is by using new Heating, Ventilation, plus A/C systems, then just having an Heating, Ventilation, plus A/C equipment is not enough on its own. The Heating, Ventilation, plus A/C idea must be kept wipe with familiar filter changes plus a rigid cleaning plus repair of the Heating, Ventilation, plus A/C idea to unfasten anything that might contaminate the air. Only after that can you rest plus have only one moderate helping of leftover lasagna, one small bowl of ice cream, plus maybe several beers. But you can breathe all that Heating, Ventilation, plus A/C conditioned air until your heart is overflowing with goodwill.
