Deep breathing in dusty places sends the particles of dust into the upper and less used lobes of the lungs, and these become a constant irritant, until they finally excite an inflammation, which may end in consumption. All occupations in which arsenic is used shorten life.
Dr. William Ogle, who is authority upon this subject, says, "Of all the various influences that tend to produce differences of mortality in any community, none is more potent than the character of the prevailing occupations." Finding that clergymen and priests have the lowest death-rate, he represented it as one hundred, and by comparison found that the rate for inn and hotel servants was three hundred and ninety-seven; miners, three hundred and thirty-one; earthenware makers, three hundred and seventeen; file makers, three hundred; innkeepers, two hundred and seventy-four; gardeners, farmers, and agricultural laborers closely approximating the clerical standard. He gave as the causes of high mortality, first, working in a cramped or constrained attitude; second, exposure to the action of poisonous or irritating substances; third, excessive work, mental or physical; fourth, working in confined or foul air; fifth, the use of strong drink; sixth, differences in liability to fatal accidents; seventh, exposure to the inhalation of dust. The deaths of those engaged in alcoholic industries were as one thousand five hundred and twenty-one to one thousand of the average of all trades.
It is very important that occupations should be congenial. Whenever our work galls us, whenever we feel it to be a drudgery and uncongenial, the friction grinds life away at a terrible rate.
Health can be accumulated, invested, and made to yield its compound interest, and thus be doubled and redoubled. The capital of health may, indeed, be forfeited by one misdemeanor, as a rich man may sink all his property in one bad speculation; but it is as capable of being increased as any other kind of capital.
One is inclined to think with a recent writer that it looks as if the rich men kept out of the kingdom of heaven were also excluded from the kingdom of brains. In New York, Boston, Philadelphia, and Chicago are thousands of millionaires, some of them running through three or four generations of fortune; and yet, in all their ranks, there is seldom a man possessed of the higher intellectual qualities that flower in literature, eloquence, or statesmanship. Scarcely one of them has produced a book worth printing, a poem worth reading, or a speech worth listening to. They are struck with intellectual sterility. They go to college; they travel abroad; they hire the dearest masters; they keep libraries among their furniture; and some of them buy works of art. But, for all that, their brains wither under luxury, often by their own vices or tomfooleries, and mental barrenness is the result. He who violates Nature's law must suffer the penalty, though he have millions. The fruits of intellect do not grow among the indolent rich. They are usually out of the republic of brains. Work or starve is Nature's motto; starve mentally, starve morally, even if you are rich enough to prevent physical starvation.
How heavy a bill Nature collects of him in whom the sexual instinct has been permitted to taint the whole life with illicit thoughts and deeds, stultifying the intellect, deadening the sensibilities, dwarfing the soul!
"I waive the quantum of the sin,
The hazard of concealing;
But och, it hardens all within,
And petrifies the feeling."
The sense of fatigue is one of Nature's many signals of danger. All we accomplish by stimulating or crowding the body or mind when tired is worse than lost. Insomnia, and sometimes even insanity, is Nature's penalty for prolonged loss of sleep.
One of the worst tortures of the Inquisition was that of keeping victims from sleeping, often driving them to insanity or death. Melancholy follows insomnia; insanity, both. To keep us in a healthy condition, Nature takes us back to herself, puts us under the ether of sleep, and keeps us there nearly one-third of our lives, while she overhauls and repairs in secret our wonderful mechanism. She takes us back each night wasted and dusty from the day's work, broken, scarred, and injured in the great struggle of life. Each cell of the brain is reburnished and refreshened; all the ashes or waste from the combustion of the tissues is washed out into the blood stream, pumped to the lungs, and thrown out in the breath; and the body is returned in the morning as fresh and good as new. The American honey does not always pay for the sting.
Labor is the eternal condition on which the rich man gains an appetite for his dinner, and the poor man a dinner for his appetite; but the habit of constant, perpetual industry often becomes a disease.
