Just- as life is impossible without vitalized blood, so is health impossible without blood that possesses afair degree of health. And it follows just as logically that one’s vitality will be in exact ratio to the vitality of his blood.
All of the tissues of our flesh and bones are made up of infinitely small cellsso small, in fact, that hundreds of them, if massed, would be invisible across the- table. Each cell is born, lives and dies by itself. As fast as a cell diesand some of them live but a few minutes, or a few hoursa new cell is supplied to take its place.
Exercise, even of the slightest, such as opening or closing the hand, destroys a multitude of cells. Even thinking causes the death of cells, and Nature immediately supplies new cells to take the place of those that are defunct. One of the important benefits of bodily exercise is that it’ causes the destruction death-of many all but exhausted cells, which, in turn, are replaced by cells that are full of lifevitality.
But the cells die, too, in a body that is actually without motion, in a body whose brain is in a state of complete lethargy. The only difference is that in the inactive body the cells do not die as soon as they should, nor are the new cells by which they are re-placed as healthy as they should be.
All- of this repair work in the body is done by the blood. That fluid carries to all of the tissues of the body the fresh matter that is to build up new, vitalized cells in the place of those that are dying. This repair material is secreted from the food that is digested in the stomach and in the intestines. Hence the need of the most nourishing of foods. Improper food furnishes but poor repair material. That which goes into the stomach and is digested becomes the actual, living body. In this connection I cannot help but refer once more to the value of adopting, if not wholly, then partly, an uncooked or natural diet. As stated more fully in another chapter, cooking destroys to a great extent and sometimes entirely, the cell-life of the food intended to nourish the body.
It is reasonable then that this devitalized or dead cell matter will never furnish material of a suitable kind for building up or even repairing the body. WE ARE JUST WHAT WE MAKE OURSELVES THROUGH THE ACT OF EATING.
But the blood does more than this. From the air that is breathed into the lungs the blood takes oxygen, and carries it through all the parts of the body. Wherever the gas encounters dead cell-matter it burns it up, and the results of the combustion are carried by the blood to the lungs, there to be eliminated from the body.
Now, you will easily understand why the blood must be pure and rich. At the very foundation of increased vitality must come a radical improvement in the quality of the blood.
While food is the basis of the tissue-building power of the blood, a generous amount of water is needed to maintain the fluids of the body in a proper condition so that they may flow freely. Deep, full breathing of pure air must be had in order that the dead cells may be burned up as fully as is possible.
Exercise plays an important part in the bodily processes just related, also increases the powers of digestion by giving greater muscular activity to the stomach and intestines, while the heavier, more frequent breathing caused by muscular effort forces the heart into more rapid action, and sends the blood coursing through the body on its repair and purifying mission at an increased speed.
From this brief statement the reader will be able to understand fully that vitality depends upon the blood, and that the purity of the blood is contingent on the selection and digestion of the right foods, exercise, breathing, and the drinking of sufficient quantities of water.
