The personal habits of the individual, more than any other factor, determine whether or not arteriosclerosis sets in early in his life. The man or woman who is moderate in eating and drinking, sees that the kidneys are kept in good condition, and attends strictly to regularity of the bowels, lays a good basis for the measure of health which is so essential for happiness. It has been shown that sclerosis of the splanchnic vessels may be due to constant irritation of toxic products elaborated in digesting constantly enormous meals. In obstinate constipation, many poisons, the nature of which we do not know, are absorbed and circulate in the blood. We have not sufficient data to prove that constipation favors the production of arteriosclerosis, but our impression has been that it does favor it. Constipation can often be relieved by a glass of water before breakfast, a regular time to go to stool, and abdominal massage or exercises. Some maintain that it is a bad habit only, and can be readily overcome. Whatever is done, avoid leading the patient into the drug habit, for the last state of the patient will be worse than the first. Habits of sleep are not of such great importance. Most persons get enough sleep except when under severe mental strain. Most adults need from seven to eight hours' sleep, although some can do all their work and keep in prime health on five or six hours' sleep. Tobacco has been accused of causing many ills and has been thereby much maligned. We can not see that the use of tobacco in any form in moderation is harmful to most men. Undoubtedly the blood pressure is raised when mild tobacco poisoning occurs, and individual peculiarities of reaction to the weed are multitudinous. But to condemn offhand its use is the height of folly. There is no reason why the arteriosclerotic who has always used tobacco in moderation, should not continue to use it, whether he smoke cigarettes, cigars, or pipe. His supply should be decreased, but there is no sense in depriving a man of one of the solaces of life, unless, as is sometimes the case, abstinence is easier for the patient than moderation.
