Exophthalmic goiter is a disease characterised by enlargement of the thyroid gland, protrusion of the eyeballs, and rapid beating of the heart. The disease is confined almost entirely, though not exclusively, to women, and I should not advise any exophthalmic woman to marry; neither should I advise a man to marry an exophthalmic goiter woman. It is a very annoying disease, while sexual intercourse aggravates all the symptoms, particularly the palpitation of the heart. The children, if not affected by exophthalmic goiter, are liable to be very neurotic.
Simple goiter, that is, enlargement of the thyroid gland (chiefly occurring in certain high mountainous localities, such as Switzerland), is not so strongly dysgenic as is exophthalmic goiter. Still, goiter patients are not good matrimonial risks.
Of course, there are always exceptions. I know an exophthalmic goiter woman who brought up four children, and very good, healthy children they are. But in writing we can only speak of the average and not of exceptions.
Obesity must be considered a dysgenic factor. The obese are subject to heart disease, asthma, apoplexy, gallstones, gout, diabetes, constipation; they withstand pneumonia and acute infectious diseases poorly, and they are bad risks when they have to undergo major surgical operations. They also, as a rule, are readily fatigued by physical and mental work. (As to the latter, there are remarkable exceptions. Some very obese people can turn out a great amount of work, and are almost indefatigable in their constant activity.) Each case should be considered individually, and with reference to the respective family history. If the obese person comes from a healthy, long lived family and shows no circulatory disturbances, no strong objections can be raised to him or to her. But, as a general proposition, it must be laid down that obesity is a dysgenic factor.
But bear in mind that obesity and stoutness are not synonymous terms.
It must be borne in mind that the sexual act is, in itself, a danger to arteriosclerotics and people with high blood pressure, because it may bring about rupture of a blood-vessel. There are many cases of sudden death from this cause of which the public naturally never learns. Married persons who find that they have arteriosclerosis or high blood pressure should abstain from sexual relations altogether or indulge only at rare intervals and moderately.
We know now that gout is caused by excessive eating, excessive drinking, lack of exercise, and faulty elimination. And, since, as a general thing, children lead the same lives that their fathers did, they are likely to develop the same diseases as their fathers did. A poor man who leads an abstemious life doesn't develop gout, and if his children lead the same abstemious lives they do not develop gout. (There are some cases of gout among the poor, but they are very rare.) But if they should begin to gorge and live an improper life they would be prone to develop the disease.
The disease, therefore, cannot in any way be considered hereditary. In matrimony, gout in either of the couple is not a desirable quality, but it is not a bar to marriage; and, if the candidate individually is healthy and free from gout, the fact that there was gout in the ancestry should play no rôle.

Obesity
Obesity, or excessive stoutness, is an undue development of fat throughout the body. That it is hereditary, that it runs in families, there is no question whatsoever. And, while with great care as to the diet and by proper exercise, obesity may, as a rule, be avoided in those predisposed, it none the less often will develop in spite of all measures taken against it. Some very obese people eat only one-half or less of what many thin people do; but in the former, everything seems to run to fat.Obesity must be considered a dysgenic factor. The obese are subject to heart disease, asthma, apoplexy, gallstones, gout, diabetes, constipation; they withstand pneumonia and acute infectious diseases poorly, and they are bad risks when they have to undergo major surgical operations. They also, as a rule, are readily fatigued by physical and mental work. (As to the latter, there are remarkable exceptions.

But, as a general proposition, it must be laid down that obesity is a dysgenic factor.

Arteriosclerosis
Arteriosclerosis means hardening of the arteries. All men over fifty are beginning to develop some degree of arteriosclerosis; but, if the process is very gradual, it may be considered normal and is not a danger to life; when, however, it develops rapidly and the blood pressure is of a high degree, there is danger of apoplexy. Consequently, arteriosclerosis and high blood pressure must be considered decided bars to marriage.It must be borne in mind that the sexual act is, in itself, a danger to arteriosclerotics and people with high blood pressure, because it may bring about rupture of a blood-vessel. There are many cases of sudden death from this cause of which the public naturally never learns. Married persons who find that they have arteriosclerosis or high blood pressure should abstain from sexual relations altogether or indulge only at rare intervals and moderately.
Gout
A consideration of gout in connection with the question of heredity will show how near-sighted people can be, how they can go on believing a certain thing for centuries without analyzing, until somebody suddenly shows them the absurdity of the thing. Gout was always considered a typical hereditary disease; for it was seen in the grandfathers, fathers, children, grandchildren, and so on. So, certainly, it must be hereditary! It did not come to our doctors' minds to think that perhaps, after all, it was not heredity that was to blame, but simply that the same conditions that produced gout in the ancestors likewise produced it in their descendants.We know now that gout is caused by excessive eating, excessive drinking, lack of exercise, and faulty elimination. And, since, as a general thing, children lead the same lives that their fathers did, they are likely to develop the same diseases as their fathers did. A poor man who leads an abstemious life doesn't develop gout, and if his children lead the same abstemious lives they do not develop gout. (There are some cases of gout among the poor, but they are very rare.) But if they should begin to gorge and live an improper life they would be prone to develop the disease.
The disease, therefore, cannot in any way be considered hereditary. In matrimony, gout in either of the couple is not a desirable quality, but it is not a bar to marriage; and, if the candidate individually is healthy and free from gout, the fact that there was gout in the ancestry should play no rôle.
