This volume contains a miscellany of papers and the group discussions that followed them at the fifth Ciba Colloquium on Aging. Among the topics presented are the effect of parental age on the longevity of man and of racehorses; aging in bees, Drosophila, and other insects; aging in fish, both in nature and in captivity; the lifespan of and arteriosclerosis in birds; and the relation of the age of onset of degenerative disease to the lifespan of the rat and of man. It is, however, in the group discussions that the greatest interest lies. Through these discussions attention is drawn to the tremendous gaps in the knowledge of aging, which handicap man's attempts to postpone and ameliorate senescence. Important problems of the study of aging are those of time and cost; many experiments, to be conducted properly, need 30 to 100 years of research before conclusive data can be collected
