senescence, aging, decay
A complete study of senescence would involve, not only a consideration of man, but of lower organisms, animal and plant, as well as institutions, races, nations, even the cosmos itself; for assuredly the phenomena of decay are as universal and intricate as those of genesis. In the present study, however, it will be attempted merely to indicate, first, the best that has already been done upon human senescence; second, to add further findings; and third, to set more definitely a number of new problems for future investigation.
