"We hear a great deal about the 'vile body,'" said Spencer, "and many are encouraged by the phrase to transgress the laws of health. But Nature quietly suppresses those who treat thus disrespectfully one of her highest products, and leaves the world to be peopled by the descendants of those who are not so foolish."
Nature gives to him that hath. She shows him the contents of her vast storehouse, and bids him take all he wants and be welcome. But she will not let him keep for years what he does not use. Use or lose is her motto. Every atom we do not utilize this great economist snatches from us.
If you put your arm in a sling and do not use it, Nature will remove the muscle almost to the bone, and the arm will become useless, but in exact proportion to your efforts to use it again she will gradually restore what she took away. Put your mind in the sling of idleness, or inactivity, and in like manner she will remove your brain, even to imbecility. The blacksmith wants one powerful arm, and she gives it to him, but reduces the other. You can, if you will, send all the energy of your life into some one faculty, but all your other faculties will starve.
A young lady may wear tight corsets if she chooses, but Nature will remove the rose from her cheek and put pallor there. She will replace a clear complexion with muddy hues and sallow spots. She will take away the elastic step, the luster from the eye.
Don't expect to have health for nothing. Nothing in this world worth anything can be had for nothing. Health is the prize of a constant struggle.
Nature passes no act without affixing a penalty for its violation. Whenever she is outraged she will have her penalty, although it take a life.
A great surgeon stood before his class to perform a certain operation which the elaborate mechanism and minute knowledge of modern science had only recently made possible. With strong and gentle hand he did his work successfully so far as his part of the terrible business went; and then he turned to his pupils and said, "Two years ago a safe and simple operation might have cured this disease. Six years ago a wise way of life might have prevented it. We have done our best as the case now stands, but Nature will have her word to say. She does not always consent to the repeal of her capital sentences." Next day the patient died.
Apart from accidents, we hold our life largely at will. What business have seventy-five thousand physicians in the United States? It is our own fault that even one-tenth of them get a respectable living. What a commentary upon our modern American civilization that three hundred and fifty thousand people in this country die annually from absolutely preventable diseases! Seneca said, "The gods have given us a long life, but we have made it short." Few people know enough to become old. It is a rare thing for a person to die of old age. Only three or four out of a hundred die of anything like old age. But Nature evidently intended, by the wonderful mechanism of the human body, that we should live well up to a century.
Thomas Parr, of England, lived to the age of one hundred and fifty-two years. He was married when he was a hundred and twenty, and did not leave off work until he was a hundred and thirty. The great Dr. Harvey examined Parr's body, but found no cause of death except a change of living. Henry Jenkins, of Yorkshire, England, lived to be a hundred and sixty-nine, and would probably have lived longer had not the king brought him to London, where luxuries hastened his death. The court records of England show that he was a witness in a trial a hundred and forty years before his death. He swam across a rapid river when he was a hundred.
There is nothing we are more ignorant of than the physiology and chemistry of the human body. Not one person in a thousand can correctly locate important internal organs or describe their use in the animal economy.
