One can’t maintain dismissive skepticism forever in the face of scientific and medical development communities that are ever more engaged in the development of therapies to address the mechanisms of aging. To pick one example, senolytic treatments that clear senescent cells from aged tissues are producing consistently amazing data in mice: rejuvenation, extension of healthy life, reversal of measures of many specific age-related diseases. We’ll soon know how well the more viable senolytics perform in human trials, as the preliminary data from the use of dasatinib and quercetin shows that it does selectively destroy senescent cells in humans as it does in mice. Given the serious prospect of living longer in good health, I would expect the previously doom and gloom crowd of naysayers to capitulate and admit that, yes, actually it would be pleasant to have more health, more life, and less pain, suffering, and death.
People are living longer, staying healthier longer and accomplishing things late in life that once seemed possible only at younger ages. And it’s not just superstars. The fraction of over-85s in the U.S. classified as disabled dropped by a third between 1982 and 2005, while the share who were
