1progressive accumulation of inert substances in all the tissues, and especially in the walls of the veins and arteries, which thus become sclerotic.
2If the accumulation of these substances is not halted, other tissues will later suffer the consequences — a true deterioration being produced in them which will carry them to the loss of the elasticity characteristic of youth and the establishment of the inelasticity characteristic of old age.
3To halt that accumulation, and little by little to eliminate the calcareous substances already deposited, physical exercises are needed which will be indicated in due course.
4That readers may have a clear idea of what really occurs in the arteries and veins — especially the former — let them imagine the calcareous incrustations that appear in the tubes of a boiler or steam engine after a certain time, above all if the boiling water was saturated with salts.
5If those tubes are not cleaned they are very soon obstructed and become useless; but if the incrustations are removed they recover their original efficiency.
6Exactly the same happens with the arteries — with the sole difference that, while in the example given the salts deposit on the internal surface of the tubes, in the arteries they deposit in the intercellular spaces of the walls, thus giving origin to that syndrome well known under the name of arteriosclerosis.
7This characteristic senile manifestation cannot be cured by any medicinal preparation (despite the many existing for that end, among which we mention the best known: iodine), nor by any dietetic regime.
8It is true that by following a dietetic regime relatively poor in certain salts — such as a very suitable and balanced vegetarian regime based on much fruit — arteriosclerosis can be avoided; but once it is established, the regime mentioned no longer suffices to eliminate the salts deposited.
9Once arteriosclerosis is manifest — principally by deposit of carbonates and phosphates (a deposit that may also occur, and principally, in the gall-bladder and kidneys, giving origin to the well-known calculi) — the arteries become hard, losing their normal elasticity; and in consequence the irrigation and adequate distribution of the blood through the various organic territories becomes ever more difficult, even though the great sympathetic and the vagus nerve strive to maintain an adequate vasoconstriction or vasodilation.
10Then the poor circulation gradually determines the atrophy of the various tissues, with attenuation of the organic functions and visible manifestation of all those characteristics of senility.
11That is why, for example, the brain begins to function ever less intensely — confusion of ideas, loss of memory, failure of attention, etc., thus manifesting themselves, which, as is known, are prevalently manifestations of premature senility or of very advanced old age.
