And as to the effects, they are such, and have all along been such, as to make me wonder at myself, whenever I think of it. Instead of being constantly subject to cold, and nearly dying with consumption in the spring, I am almost free from any tendency to take cold at all. During the winter of 1837-8, by neglecting to keep the temperature of my room low enough, and by neglecting also to take sufficient exercise in the open air, I became unusually tender, and suffered to some extent from colds. But I was well again during the spring, and felt as if I had recovered or nearly recovered my former hardihood.
In regard to other complaints, I may say still more. Of rheumatism, I have scarcely had a twinge in twelve or fourteen years. My eruptive complaint is, I believe, entirely gone. The weakness of my eyes has been wholly gone for many years. Indeed, the strength and perfection of my sight and of all my senses, till nearly fifty years of age—hearing perhaps excepted, in which I perceive no alteration—appeared to be constantly improving. My stomach and intestines perform their respective duties in the most appropriate, correct, and healthful manner. My appetite is constantly good, and as constantly improving;—that is, going on toward perfection. I can detect, especially by taste, almost any thing which is in the least offensive or deleterious in food or drink; and yet I can receive, without immediate apparent disturbance, and readily digest, almost any thing which ever entered a human stomach—knives, pencils, clay, chalk, etc., perhaps excepted. I can eat a full meal of cabbage, or any other very objectionable crude aliment, or even cheese or pastry—a single meal, I mean—with apparent impunity; not when fatigued, of course, or in any way debilitated, but in the morning and when in full strength. It is true, I make no experiments of this sort, except occasionally as experiments.
In my former statements I gave it as my opinion that vegetable food was less aperient than animal. My opinion now is, that if we were trained on vegetable food, and had never received substances into the stomach which were unduly stimulating, we should find the intestinal or peristaltic action quite sufficient. The apparent sluggishness of the bowels, when we first exchange an animal diet for a vegetable one, is probably owing to our former abuses. At present, I find my plain vegetable food, in moderate and reasonable quantity, quite as aperient as it ought to be, and, if I exceed a proper quantity, too much so.
I have now no remaining doubts of the vast importance that would result to mankind, from an universal training from childhood, to the exclusive use of vegetable food. I believe such a course of training, along with a due attention to air, exercise, cleanliness, etc., would be the means of improving our race, physically, intellectually, and morally, beyond any thing of which the world has yet conceived. But my reasons for this belief will be seen more fully in another place. They are founded in science and the observation of facts around me, much more than on a narrow individual experience.
There is one circumstance which I must not omit, because it is full of admonition and instruction. I have elsewhere stated that, twenty-three years ago, I had incipient phthisis. Of this fact, and of the fact that there were considerable inroads made by disease on the upper lobe of the right lung, I have not the slightest doubt. The symptoms were such at the time, and subsequently, as could not have been mistaken. Besides, what was, as I conceive, pretty fully established by the symptoms which existed, is rendered still more certain by auscultation. The sounds which are heard during respiration, in the region to which I have alluded, leave no doubt on the minds of skillful medical men, of their origin. Still I doubt whether the disease has made any considerable progress for many years.
But, during the winter of 1837-8, my employments became excessively laborious; and, for the whole winter and spring, were sufficient for at least two healthy and strong men. They were also almost wholly sedentary. At the end of May, I took a long and rather fatiguing journey through a country by no means the most healthy, and came home somewhat depressed in mind and body, especially the former. I was also unusually emaciated, and I began to have fears of a decline. Still, however, my appetite was good, and I had a good share of bodily strength. The more I directed my attention to myself, the worse I became; and I actually soon began to experience darting pains in the chest, together with other symptoms of a renewal of pulmonary disease. Perceiving my danger, however, from the state of my mind, I at length made a powerful effort to shake off the mental disturbance—which succeeded. This, together with moderate labor and rather more exercise than before, seemed gradually to set me right.
Again, in the spring of 1848, after lecturing for weeks and months—often in bad and unventilated rooms and subjecting myself, unavoidably, to many of those abuses which exist every where in society, I was attacked with a cough, followed by great debility, from which it cost me some three months or more of labor with the spade and hoe, to recover. With this and the exceptions before named, I have now, for about twenty years, been as healthy as ever I was in my life, except the slight tendency to cold during the winter of which I have already taken notice. I never was more cheerful or more happy; never saw the world in a brighter aspect; never before was it more truly "morning all day" with me. I have paid, in part, the penalty of my transgressions; and may, perhaps, go on, in life, many years longer.
I now fear nothing in the future, so far as health and disease are concerned, so much as excessive alimentation. To this evil—and it is a most serious and common one in this land of abundance and busy activity—I am much exposed, both from the keenness of my appetite, and the exceeding richness of the simple vegetables and fruits of which I partake. But, within a few years past, I seem to have gotten the victory, in a good measure, even in this respect. By eating only a few simple dishes at a time, and by measuring or weighing them with the eye—for I weigh them in no other way—I am usually able to confine myself to nearly the proper limits.
This caution, and these efforts at self-government, are not needed because their neglect involves any immediate suffering; for, as I have already stated, there was never a period in my life before, when I was so completely independent—apparently so, I mean—of external circumstances. I can eat what I please, and as much or as little as I please. I can observe set hours, or be very irregular. I can use a pretty extensive variety at the same meal, and a still greater variety at different meals, or I can live perpetually on a single article—nay, on almost any thing which could be named in the animal or vegetable kingdom—and be perfectly contented and happy in the use of it. I could in short, eat, work, think, sleep, converse, or play almost all the while; or I could abstain from any or all of these, almost all the while. Let me be understood, however. I do not mean to say that either of these courses would be best for me, in the end; but only that I have so far attained to independence of external circumstances that, for a time, I believe I should be able to do or bear all I have mentioned.
