Aerobic activity is essential to optimize your body's blood-oxygen supply. Every one of the 50 trillion cells in your body (assuming that you are an average-sized adult) is a complex factory that is constantly breaking down minerals and nutrients and processing them to produce heat, energy, and new cell material to replace damaged and worn out cell material. For this sophisticated process each cell needs a constant, uninterrupted supply of oxygen that can only be transported through the blood. Equally important, the blood must carry away from each cell its toxic wastes like carbon dioxide.
When you are at rest your body doesn't use up much oxygen, but when you must do some kind of vigorous activity like climbing a flight of stairs or running to catch a buss, your body may require 20 to 25 times its normal oxygen level. There must always be enough blood in your system to deliver an adequate blood supply to each cell.
God has designed your body in such a way that it will always adjust itself to what is being required of it. If the most vigorous activity you normally do is no more strenuous than picking up a TV remote, your body will adjust itself to that level of stress. Any body tissue, including blood, which is not normally active, will waste away. Why should your body work to maintain blood and other tissues that it doesn't need?
While you are relaxing everything seems fine. But what happens if you must exert yourself? You have to run to catch a plane, or you have to push a car that is stalled or you must face some emergency. Suddenly every cell in your body requires a surge of oxygen to produce extra energy for the situation at hand. Your lungs heave to absorb more oxygen, and your heart pounds to deliver it, but the oxygen supply just cannot be delivered because there is not enough blood to deliver it. In desperation the heart and lungs may overwork themselves in order to compensate for the inadequate blood supply. Eventually the heart and lungs may damage themselves, and the results could be fatal.
A normal-sized, unconditioned person will probably have about 5 quarts of blood in his system. But if you partake in regular, vigorous aerobic activity, your body will adjust to the extra demands being placed upon it. Eventually your blood volume may increase by as much as a quart or more, depending on how much you do. Since you have more blood to carry the oxygen, your heart and lungs don't have to work nearly as hard. If it becomes normal for you to run two or three miles a day, you probably will not exhaust yourself climbing a flight of stairs.
