Coleen T. Murphy, a professor at Princeton University, specializes in genomics and molecular biology and is the author of How We Age: The Science of Longevity.  In this wide-ranging interview we discuss the significance of declining cellular repair mechanisms that over time lead to visible signs of aging. Prof. Murphy has a particular interest in reproductive aging and cognitive function during aging, considering the former as an often overlooked aspect that begins midlife.  Prof. Murphy also expresses concern about the way longevity science is portrayed and criticizes some researchers for failing accurately to describe the true implications of their work. She says there is a need for honesty and realism from scientists to maintain public trust, especially in the field of aging and longevity where bold claims can often outpace reality. Researchers, she insists, should not over-promise results that science cannot yet deliver.  We also address the potential for 'exercise in a pill' while Prof. Murphy argues that without taking care of our planet and its inhabitants, the quest for longevity loses much of its significance.
