THE “TWELVE COMMANDMENTS” FOR THE PRESERVATION OF 455 YOUTH, AND THE ATTAINMENT OF A GREEN OLD AGE GLOSSARY 459 INDEX 467 ------------------------------------------------------------------------ SPECIAL ANNOUNCEMENT TO THE READERS OF “OLD AGE DEFERRED.” WE have just recently received the manuscript for the following introductory pages, which are intended as a message direct to the American people by Dr. Lorand. Their importance justifies a careful reading. Although, in accordance with his duty as a citizen of Austria, Dr. Lorand has had to practically abandon his private practice, and devote his energies and his abilities to the service of his country in the time of trial, he has, nevertheless, been so situated as to have a pretty intimate knowledge of American affairs. He has been especially grieved and shocked to learn of so many sudden, untimely, and in his judgment, unnecessary deaths among prominent Americans since the great war began. Counting as he did, a great number of friends, not only among American physicians, but among American tourists, and knowing, as he does, so intimately, the peculiar physical characteristics of the high-grade American citizen, he is appalled at the wastage of valuable lives in a country teeming with prosperity and incidental home comforts. The following introduction is designed as a warning to high-pressure Americans that by a little care and the exercise of reasonable judgment a large number of these premature deaths may be prevented. Even if you were to read no further, the careful perusal of this introduction is well worth while, as it deals directly with the most important personal problems. THE PUBLISHERS. ------------------------------------------------------------------------
