Produktbeschreibung

Egocentricity is characteristically human. It is natural for our prime in terest to be ourselves and for one of our major concerns to be what affects us personally. Aging and death - universal and inevitable have always been of compelling concern. Mystical explanations were invented when scientific answers were lacking. and gross physiologi As scientific knowledge developed, anatomy cal processes were explained, and the roles of the endocrine glands were revealed. Since the sex hormones obviously lose some of their potency with age, it was logical to assume that they played the major role in declining general well-being. The puzzle of aging would now be solved. The Ponce de Leon quest would soon be fulfilled. Pseudoscientists and quacks rushed in where most scientists feared to tread. By the time the glowing promises of perpetual youth through gland transplants and injections had proved illusory, serious study of the aging process had been set back for years. The field had lost "respect ability," and most capable scientists shunned it. Those who did con tinue to seek answers to its tough questions deserve special recognition.
