To _keep_ yourself in health without medicine is what we intend to convey; and we assert that but little or no medicine is necessary to reach that condition. To have happiness without any money (in the present condition of society) is not what we claim, but that more happiness can be extracted from a competency than by more or less. To live to good old age means with us 80 to 120 years, to increase with future generations, when order, regularity, sobriety, cleanliness, and love for the whole human family, shall be paramount in the political, moral, and intellectual world. The author is living on thirty years of made land. In other words, according to medical diagnosis, he should have _died_ thirty years ago! Hence he desires to put before the unhealthy, unhappy, and short-lived human race the result of his experience of half a century. Having battled with a score of diseases, a number of which were claimed to be absolutely incurable--having freed himself entirely of them all--having been completely restored to health and happiness, he honestly believes that he has a convincing right to be heard. You can now prove for yourself. PART I. CHAPTER I. "Health is the vital principle of bliss, And exercise of health." _Health_, _Happiness_, and _Longevity_. What a talisman is here! In them is the magic that can rule all men. No seal, figure, character, engraven on a sympathetic stone, can equal their single or combined influence. Say to your fellow-man, "If you follow my direction I will confer upon you health, happiness, and longevity," and you will receive his lasting gratitude. He will always be your friend. Money is potent, but these qualities are, as it were, omnipotent. Money alone cannot bring them; they alone can make wealth. This work is _not_ a _philosophical_ treatise, difficult to read and more so to comprehend. Its ideas are simple, the result of long _experience_ and _observation_. Its propositions are easily demonstrated. Then, my reader, do not think you are perusing the hobbies of a crank, the fantasies of a dreamer, and the preachings of him who does not practice. The world has been so flooded with worthless productions of such characters that we fear we must combat severe _prejudice_. Will you lay that aside? If so we will not only interest but instruct you. Agreeing with our premises and conclusions, you will certainly reap some benefit; not agreeing, you will be tempted to further investigation, which will inevitably prove the strength of our position.
