Scientific and ethical concerns regarding engineering human longevity

Abstract

The goal of biogerontological research is to elucidate the biological factors underlying adverse age-related changes in structure and function of molecules, cells, tissues, and organisms. In spite of the considerable progress achieved so far, it is still too early to predict what strategies will be both safe and effective at preventing, delaying, or reversing these changes in humans, and whether such strategies will also increase longevity.
