"Though there are a plethora of innovations being explored to extend longevity ... it is not yet clear how many of these research endeavors will materialize as practical interventions in the foreseeable future and whether they will lead to meaningful improvements in health, rather than solely extensions of life. However, the existing literature contains evidence of the material impacts that stem from healthy lifestyle behaviors and chronic condition management. The primary purpose of this report is to review this literature to provide a resource for actuaries and others on relevant issues, and secondarily to call out areas of emerging evidence that could be further researched."
