that at that time actual abstainers were almost unknown among the students, and we classified in the alcoholic group those who consumed very large quantities of alcohol; whilst the members of the sexual group certainly also consumed alcohol, though not very much. Beyond question, the common belief that there is an association between the free use of alcohol and sexual excesses is one which lacks foundation. This view is to too great an extent based upon criminal statistics, and upon the records of the perversions to which the sexual perverts among alcoholics have been inclined. But think of the countless normal persons in whom the enjoyment of alcohol induces no tendency to sexual excesses; and, on the other hand, abstainers from alcohol have been personally known to me whom no one could venture to call moderate in their sexual relations. But although I make all these reservations with regard to the effects of the use of alcohol by adults, I am in full accord with the view that the use of alcohol should be prohibited to children. Alcohol cannot do any good to children, and the possibility that in individual instances it may stimulate the sexual imagination, is one which cannot be denied. But this fact does not justify us in advising against the moderate use of alcohol by adults.[150] Passing to consider the general mode of life, we certainly agree with Hufeland, who, in his _Makrobiotik_, recommends vigorous bodily activity. He contends that children who go to bed at night healthily tired out, will not be likely to think of masturbation. In the present age of sports and games it will not be found difficult to fulfil this indication; and we see as a matter of fact that a great deal of trouble is taken to give children every opportunity of keeping in active movement. Even in our large towns, in which, owing to the lack of a sufficiency of open spaces, great difficulties have arisen in this respect, much has of late been done to improve matters. For many years past in England special efforts have been made to provide such playgrounds for children and adults.
