Old Age Deferred: The causes of old age and its postponement by hygienic and therapeutic measures

"Old Age Deferred" by Arnold Lorand is a scientific publication written in the early 20th century. The book explores the causes of aging and how it can be postponed through various hygienic and therapeutic measures, emphasizing the role of glands in the body and their connection to the aging process. The author aims to provide insight into practical strategies to prolong youthfulness and mitigate the effects of old age. The opening of "Old Age Deferred" sets the stage for the book's exploration of aging-related phenomena. Lorand begins by discussing the serious health implications caused by conditions like arteriosclerosis, pointing out that premature deaths could often be prevented through better understanding of hygiene and health practices. He establishes the premise that, while complete rejuvenation is unattainable, it is possible to extend one's youthful vitality by adhering to specific medical and lifestyle recommendations. The first chapter introduces the idea that symptoms of aging can manifest much earlier in life than expected, linking these to glandular degeneration and metabolism issues, particularly focusing on the thyroid and other ductless glands, which are identified as critical to maintaining a youthful state.
