[Footnote 39: William Cullen Bryant,——a most worthy model, mentally, morally, and physically——thus explains how he had “reached a pretty advanced period of life without the usual infirmities of old age.” Next to his abstemious and mostly vegetable diet, and pure moral life, we may well agree with him in the belief that his wonderful preservation was largely due to his custom of going to bed early and early rising, and “for a full hour, immediately upon rising, with very little encumbrance of clothing, taking a series of exercises, designed to expand the chest, and at the same time call into action all the muscles and articulations of the body,” followed by a bath “from head to foot.”——_Hygiene of the Brain_: $1.50[C] New York, M. L. Holbrook.] [Footnote C: This most valuable work contains letters from a score or more of eminent men and women who have lived to advanced age, descriptive of their living habits. The similarity of their mode of life is a feature worthy of remark.] STRAINING at stool is, beyond a slight degree, abnormal, or is made necessary only by abnormal conditions, which render defecation difficult; it tends to perpetuate and increase the difficulty, and should not be practiced ordinarily. The congestion and engorgement of the blood-vessels in the region of the rectum and anus from various causes, as retained fecal matters, or irritation and congestion of the genital organs (which two causes act and react upon each other), produce hemorrhoids (piles), and this complaint is aggravated by the straining referred to. In such cases resort must be had to cool or tepid injections for a time. One effect of deep breathing, from either exercise or habit——filling the lungs in such a manner as to press the diaphragm downward——is to cause regular pressure on the bowels, which aids in exciting their vermicular motion, and facilitates the action, both of the small intestines as digesters, and of the lower bowel in its secretory and excretory functions. The “movement,” when natural, consists of _waste matters secreted from the blood_ by the glands of the colon, and not, as is popularly supposed, of food substances, at least not to any considerable degree. When it does (and I am bound to say that this is the rule, rather than the exception), it is because the person has eaten at least _that much_ more than he ought. A good rule for many who suffer tortures of mind because of constipation would be: mind your own business and let your bowels mind theirs. Strive not to _have_ movements, but rather to _deserve_ them. That is, attend to the general health by living hygienically, and the bowels will, if given _regular opportunity_, move when there is anything to move for! With infants or young children, a little excess of food will, at first, occasion a little looseness, or increased action, usually; deficiency in diet would cause constipation. The remedy in either case is plain: a little less food in the one case, a little more in the other. The
