We went to war to make the world safe for democracy, and we put several millions of our young men into armies, and if there were any of them who did not already know how to smoke cigarettes, they learned it under official sanction. So now we have a national tobacco bill that runs up to two billions, and will insure us a new generation of "Class C" rating. Speaking to the young radicals who are reading my books, I say: We want to make the world over, to make it a place of freedom and kindness, instead of the hell of greed and hate that it is today. For that purpose we need a new moral code, and we can never win our victory without it. I have attended radical conventions, sitting in unventilated halls amid clouds of tobacco smoke, and listening to men wrangle all through the day and a great part of the night; I have watched the fatal dissensions in the movement, the quarrelings of the right wingers and the left wingers and all stages and degrees in between, and I have wondered--not jestingly, but in pitying earnest--how much of all those personalities and factional misunderstanding had their origin in carbon dioxide and nicotine. There is no use suggesting such ideas to the older men, whose habits are fixed; but a new generation is coming on, with a new vision of the enormous task before it; and is it too much to expect of these young men and women, that they shall realize in advance the grim tasks they have to do, and shall learn to run the machine of their body so as to get out of it the maximum amount of service? Is it too much to hope for, that some day we shall have a race of young fighters for truth and justice, who are willing to live abstemious lives, and consecrate themselves to the task of delivering mankind from wage slavery and war? CHAPTER XXIII MORE ABOUT HEALTH (Discusses the subjects of breathing and ventilation, clothing, bathing and sleep.) In discussing the question of health, we have given the greater part of the space to the subject of diet, for the reason that experience has convinced us that diet is two-thirds of health, and that nearly always in disease you find errors of diet playing a part. There are, however, other important factors of health, now to be discussed.
