Deletion of Reliability theory of aging and longevity

Comment: Publication in the ''https://books.google.co.uk/books?id=7YS0F5dORV0C&pg=PA4 Handbook of the Biology of Aging'' seems adequate evidence of notability.  Secondary commentary appears in the ''https://books.google.co.uk/books?id=IW0t6V3Dy1IC&pg=PA48 Handbook of Gerontology''.  These are from respectable publishers and there are obvious |alternatives to deletion such as merger into Senescence#Theories_of_aging
