In the aggregate, milder forms of unhealthy living interfere with industrial efficiency even more than alcoholism. Many capable men and women, even those who have had thorough technical training, fail to win promotion because their persons are not clean, their breath offensive, their clothes suggestive of disorderly, uncleanly habits. Persons of extraordinary capacity not infrequently achieve only mediocre results because they fail to cultivate habits of cleanliness and health. An employer can easily protect his business from loss due to alcoholism among his own employees; but loss through employees' constipation, headache, bad ventilation at home, irregular meals, improper diet, too many night parties, nicotinism, personal uncleanliness, is loss much harder to anticipate and avoid. Because evil results are less vivid, it is also hard to convince a clerk that intemperance in eating, sleeping, and playing will interfere with his earning capacity and his enjoyment capacity quite as surely as intemperance in the use of alcohol and nicotine. Where employees are paid by the piece, instead of by the hour, day, or week, the employer partially protects himself against uneven, sluggish, slipshod workmen; but, other things being equal, he awards promotion to those who are most regular and who are most often at their best, for he finds that the man who does not "slump" earns best profits and deserves highest pay.

Your efficiency should be measured not by some other person's advancement, but by what you yourself ought to accomplish; while the effect of abusing your physical strength is shown not only in the shortening of your industrial life and in the diminishing returns from your labor, but by the decrease of national and trade efficiency. "Sweating" injures those who buy and those in the same trade who are not "sweated" just as truly as it injures the "sweated."

What acts can we make our lower nerve centers--our subconscious selves--do for us or remind us to do? The following constitutes a daily routine that should be as involuntary as the process of digestion: 1. Throw the bedding over the foot of the bed. 2. Close the window that has been open during the night. 3. Drink a glass of water. 4. Bathe the face, neck, crotch, chest, armpits (finishing if not beginning with cold water), and particularly the eyes, ears, and nose. If time and conveniences permit, bathe all over. 5. Cleanse the finger nails.
